Uses the ARP protocol to resolve a MAC address.
This function uses the ARP protocol to resolve a MAC address. The UsingIpv6 field of the EFI_PXE_BASE_CODE_MODE structure is used to determine if IPv4 or IPv6 addresses are being used. The IP address specified by IpAddr is used to resolve a MAC address. If the ARP protocol succeeds in resolving the specified address, then the ArpCacheEntries and ArpCache fields of the EFI_PXE_BASE_CODE_MODE structure are updated, and EFI_SUCCESS is returned. If MacAddr is not NULL, the resolved MAC address is placed there as well. If the PXE Base Code protocol is in the stopped state, then EFI_NOT_STARTED is returned. If the ARP protocol encounters a timeout condition while attempting to resolve an address, then EFI_TIMEOUT is returned. If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then EFI_ABORTED is returned.
| This | The pointer to the EFI_PXE_BASE_CODE_PROTOCOL instance. |
| IpAddr | The pointer to the IP address that is used to resolve a MAC address. |
| MacAddr | If not NULL, a pointer to the MAC address that was resolved with the ARP protocol. |
| EFI_SUCCESS | The IP or MAC address was resolved. |
| EFI_NOT_STARTED | The PXE Base Code Protocol is in the stopped state. |
| EFI_INVALID_PARAMETER | One or more parameters are invalid. |
| EFI_DEVICE_ERROR | The network device encountered an error during this operation. |
| EFI_ABORTED | The callback function aborted the ARP Protocol. |
| EFI_TIMEOUT | The ARP Protocol encountered a timeout condition. |

| typedef EFI_STATUS(EFIAPI * EFI_PXE_BASE_CODE_DHCP) (IN EFI_PXE_BASE_CODE_PROTOCOL *This, IN BOOLEAN SortOffers) |
Attempts to complete a DHCPv4 D.O.R.A. (discover / offer / request / acknowledge) or DHCPv6 S.A.R.R (solicit / advertise / request / reply) sequence.
This function attempts to complete the DHCP sequence. If this sequence is completed, then EFI_SUCCESS is returned, and the DhcpCompleted, ProxyOfferReceived, StationIp, SubnetMask, DhcpDiscover, DhcpAck, and ProxyOffer fields of the EFI_PXE_BASE_CODE_MODE structure are filled in. If SortOffers is TRUE, then the cached DHCP offer packets will be sorted before they are tried. If SortOffers is FALSE, then the cached DHCP offer packets will be tried in the order in which they are received. Please see the Preboot Execution Environment (PXE) Specification for additional details on the implementation of DHCP. This function can take at least 31 seconds to timeout and return control to the caller. If the DHCP sequence does not complete, then EFI_TIMEOUT will be returned. If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then the DHCP sequence will be stopped and EFI_ABORTED will be returned.
| This | The pointer to the EFI_PXE_BASE_CODE_PROTOCOL instance. |
| SortOffers | TRUE if the offers received should be sorted. Set to FALSE to try the offers in the order that they are received. |
| EFI_SUCCESS | Valid DHCP has completed. |

Attempts to complete the PXE Boot Server and/or boot image discovery sequence.
This function attempts to complete the PXE Boot Server and/or boot image discovery sequence. If this sequence is completed, then EFI_SUCCESS is returned, and the PxeDiscoverValid, PxeDiscover, PxeReplyReceived, and PxeReply fields of the EFI_PXE_BASE_CODE_MODE structure are filled in. If UseBis is TRUE, then the PxeBisReplyReceived and PxeBisReply fields of the EFI_PXE_BASE_CODE_MODE structure will also be filled in. If UseBis is FALSE, then PxeBisReplyValid will be set to FALSE. In the structure referenced by parameter Info, the PXE Boot Server list, SrvList[], has two uses: It is the Boot Server IP address list used for unicast discovery (if the UseUCast field is TRUE), and it is the list used for Boot Server verification (if the MustUseList field is TRUE). Also, if the MustUseList field in that structure is TRUE and the AcceptAnyResponse field in the SrvList[] array is TRUE, any Boot Server reply of that type will be accepted. If the AcceptAnyResponse field is FALSE, only responses from Boot Servers with matching IP addresses will be accepted. This function can take at least 10 seconds to timeout and return control to the caller. If the Discovery sequence does not complete, then EFI_TIMEOUT will be returned. Please see the Preboot Execution Environment (PXE) Specification for additional details on the implementation of the Discovery sequence. If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then the Discovery sequence is stopped and EFI_ABORTED will be returned.
| This | The pointer to the EFI_PXE_BASE_CODE_PROTOCOL instance. |
| Type | The type of bootstrap to perform. |
| Layer | The pointer to the boot server layer number to discover, which must be PXE_BOOT_LAYER_INITIAL when a new server type is being discovered. |

| typedef EFI_STATUS(EFIAPI * EFI_PXE_BASE_CODE_MTFTP) (IN EFI_PXE_BASE_CODE_PROTOCOL *This, IN EFI_PXE_BASE_CODE_TFTP_OPCODE Operation, IN OUT VOID *BufferPtr OPTIONAL, IN BOOLEAN Overwrite, IN OUT UINT64 *BufferSize, IN UINTN *BlockSize OPTIONAL, IN EFI_IP_ADDRESS *ServerIp, IN UINT8 *Filename OPTIONAL, IN EFI_PXE_BASE_CODE_MTFTP_INFO *Info OPTIONAL, IN BOOLEAN DontUseBuffer) |
Used to perform TFTP and MTFTP services.
This function is used to perform TFTP and MTFTP services. This includes the TFTP operations to get the size of a file, read a directory, read a file, and write a file. It also includes the MTFTP operations to get the size of a file, read a directory, and read a file. The type of operation is specified by Operation. If the callback function that is invoked during the TFTP/MTFTP operation does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then EFI_ABORTED will be returned. For read operations, the return data will be placed in the buffer specified by BufferPtr. If BufferSize is too small to contain the entire downloaded file, then EFI_BUFFER_TOO_SMALL will be returned and BufferSize will be set to zero or the size of the requested file (the size of the requested file is only returned if the TFTP server supports TFTP options). If BufferSize is large enough for the read operation, then BufferSize will be set to the size of the downloaded file, and EFI_SUCCESS will be returned. Applications using the PxeBc.Mtftp() services should use the get-file-size operations to determine the size of the downloaded file prior to using the read-file operations–especially when downloading large (greater than 64 MB) files–instead of making two calls to the read-file operation. Following this recommendation will save time if the file is larger than expected and the TFTP server does not support TFTP option extensions. Without TFTP option extension support, the client has to download the entire file, counting and discarding the received packets, to determine the file size. For write operations, the data to be sent is in the buffer specified by BufferPtr. BufferSize specifies the number of bytes to send. If the write operation completes successfully, then EFI_SUCCESS will be returned. For TFTP "get file size" operations, the size of the requested file or directory is returned in BufferSize, and EFI_SUCCESS will be returned. If the TFTP server does not support options, the file will be downloaded into a bit bucket and the length of the downloaded file will be returned. For MTFTP "get file size" operations, if the MTFTP server does not support the "get file size" option, EFI_UNSUPPORTED will be returned. This function can take up to 10 seconds to timeout and return control to the caller. If the TFTP sequence does not complete, EFI_TIMEOUT will be returned. If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then the TFTP sequence is stopped and EFI_ABORTED will be returned. The format of the data returned from a TFTP read directory operation is a null-terminated filename followed by a null-terminated information string, of the form "size year-month-day hour:minute:second" (i.e. d d-d-d d:d:f - note that the seconds field can be a decimal number), where the date and time are UTC. For an MTFTP read directory command, there is additionally a null-terminated multicast IP address preceding the filename of the form d.d.d.d for IP v4. The final entry is itself null-terminated, so that the final information string is terminated with two null octets.
| This | The pointer to the EFI_PXE_BASE_CODE_PROTOCOL instance. |
| Operation | The type of operation to perform. |
| BufferPtr | A pointer to the data buffer. |
| Overwrite | Only used on write file operations. TRUE if a file on a remote server can be overwritten. |
| BufferSize | For get-file-size operations, *BufferSize returns the size of the requested file. |
| BlockSize | The requested block size to be used during a TFTP transfer. |
| ServerIp | The TFTP / MTFTP server IP address. |
| Filename | A Null-terminated ASCII string that specifies a directory name or a file name. |
| Info | The pointer to the MTFTP information. |
| DontUseBuffer | Set to FALSE for normal TFTP and MTFTP read file operation. |
| EFI_SUCCESS | The TFTP/MTFTP operation was completed. |
| EFI_NOT_STARTED | The PXE Base Code Protocol is in the stopped state. |
| EFI_INVALID_PARAMETER | One or more parameters are invalid. |
| EFI_DEVICE_ERROR | The network device encountered an error during this operation. |
| EFI_BUFFER_TOO_SMALL | The buffer is not large enough to complete the read operation. |
| EFI_ABORTED | The callback function aborted the TFTP/MTFTP operation. |
| EFI_TIMEOUT | The TFTP/MTFTP operation timed out. |
| EFI_ICMP_ERROR | An ICMP error packet was received during the MTFTP session. |
| EFI_TFTP_ERROR | A TFTP error packet was received during the MTFTP session. |

| typedef EFI_STATUS(EFIAPI * EFI_PXE_BASE_CODE_SET_IP_FILTER) (IN EFI_PXE_BASE_CODE_PROTOCOL *This, IN EFI_PXE_BASE_CODE_IP_FILTER *NewFilter) |
Updates the IP receive filters of a network device and enables software filtering.
The NewFilter field is used to modify the network device's current IP receive filter settings and to enable a software filter. This function updates the IpFilter field of the EFI_PXE_BASE_CODE_MODE structure with the contents of NewIpFilter. The software filter is used when the USE_FILTER in OpFlags is set to UdpRead(). The current hardware filter remains in effect no matter what the settings of OpFlags are, so that the meaning of ANY_DEST_IP set in OpFlags to UdpRead() is from those packets whose reception is enabled in hardware - physical NIC address (unicast), broadcast address, logical address or addresses (multicast), or all (promiscuous). UdpRead() does not modify the IP filter settings. Dhcp(), Discover(), and Mtftp() set the IP filter, and return with the IP receive filter list emptied and the filter set to EFI_PXE_BASE_CODE_IP_FILTER_STATION_IP. If an application or driver wishes to preserve the IP receive filter settings, it will have to preserve the IP receive filter settings before these calls, and use SetIpFilter() to restore them after the calls. If incompatible filtering is requested (for example, PROMISCUOUS with anything else), or if the device does not support a requested filter setting and it cannot be accommodated in software (for example, PROMISCUOUS not supported), EFI_INVALID_PARAMETER will be returned. The IPlist field is used to enable IPs other than the StationIP. They may be multicast or unicast. If IPcnt is set as well as EFI_PXE_BASE_CODE_IP_FILTER_STATION_IP, then both the StationIP and the IPs from the IPlist will be used.
| This | The pointer to the EFI_PXE_BASE_CODE_PROTOCOL instance. |
| NewFilter | The pointer to the new set of IP receive filters. |
| EFI_SUCCESS | The IP receive filter settings were updated. |
| EFI_NOT_STARTED | The PXE Base Code Protocol is in the stopped state. |
| EFI_INVALID_PARAMETER | One or more parameters are invalid. |

Updates the parameters that affect the operation of the PXE Base Code Protocol.
This function sets parameters that affect the operation of the PXE Base Code Protocol. The parameter specified by NewAutoArp is used to control the generation of ARP protocol packets. If NewAutoArp is TRUE, then ARP Protocol packets will be generated as required by the PXE Base Code Protocol. If NewAutoArp is FALSE, then no ARP Protocol packets will be generated. In this case, the only mappings that are available are those stored in the ArpCache of the EFI_PXE_BASE_CODE_MODE structure. If there are not enough mappings in the ArpCache to perform a PXE Base Code Protocol service, then the service will fail. This function updates the AutoArp field of the EFI_PXE_BASE_CODE_MODE structure to NewAutoArp. The SetParameters() call must be invoked after a Callback Protocol is installed to enable the use of callbacks.

Updates the station IP address and/or subnet mask values of a network device.
This function updates the station IP address and/or subnet mask values of a network device. The NewStationIp field is used to modify the network device's current IP address. If NewStationIP is NULL, then the current IP address will not be modified. Otherwise, this function updates the StationIp field of the EFI_PXE_BASE_CODE_MODE structure with NewStationIp. The NewSubnetMask field is used to modify the network device's current subnet mask. If NewSubnetMask is NULL, then the current subnet mask will not be modified. Otherwise, this function updates the SubnetMask field of the EFI_PXE_BASE_CODE_MODE structure with NewSubnetMask.
| This | The pointer to the EFI_PXE_BASE_CODE_PROTOCOL instance. |
| NewStationIp | The pointer to the new IP address to be used by the network device. |

Enables the use of the PXE Base Code Protocol functions.
This function enables the use of the PXE Base Code Protocol functions. If the Started field of the EFI_PXE_BASE_CODE_MODE structure is already TRUE, then EFI_ALREADY_STARTED will be returned. If UseIpv6 is TRUE, then IPv6 formatted addresses will be used in this session. If UseIpv6 is FALSE, then IPv4 formatted addresses will be used in this session. If UseIpv6 is TRUE, and the Ipv6Supported field of the EFI_PXE_BASE_CODE_MODE structure is FALSE, then EFI_UNSUPPORTED will be returned. If there is not enough memory or other resources to start the PXE Base Code Protocol, then EFI_OUT_OF_RESOURCES will be returned. Otherwise, the PXE Base Code Protocol will be started, and all of the fields of the EFI_PXE_BASE_CODE_MODE structure will be initialized as follows: StartedSet to TRUE. Ipv6SupportedUnchanged. Ipv6AvailableUnchanged. UsingIpv6Set to UseIpv6. BisSupportedUnchanged. BisDetectedUnchanged. AutoArpSet to TRUE. SendGUIDSet to FALSE. TTLSet to DEFAULT_TTL. ToSSet to DEFAULT_ToS.

Disables the use of the PXE Base Code Protocol functions.
This function stops all activity on the network device. All the resources allocated in Start() are released, the Started field of the EFI_PXE_BASE_CODE_MODE structure is set to FALSE and EFI_SUCCESS is returned. If the Started field of the EFI_PXE_BASE_CODE_MODE structure is already FALSE, then EFI_NOT_STARTED will be returned.

Reads a UDP packet from the network interface.
This function reads a UDP packet from a network interface. The data contents are returned in (the optional HeaderPtr and) BufferPtr, and the size of the buffer received is returned in BufferSize. If the input BufferSize is smaller than the UDP packet received (less optional HeaderSize), it will be set to the required size, and EFI_BUFFER_TOO_SMALL will be returned. In this case, the contents of BufferPtr are undefined, and the packet is lost. If a UDP packet is successfully received, then EFI_SUCCESS will be returned, and the information from the UDP header will be returned in DestIp, DestPort, SrcIp, and SrcPort if they are not NULL. Depending on the values of OpFlags and the DestIp, DestPort, SrcIp, and SrcPort input values, different types of UDP packet receive filtering will be performed. The following tables summarize these receive filter operations.

Writes a UDP packet to the network interface.
This function writes a UDP packet specified by the (optional HeaderPtr and) BufferPtr parameters to the network interface. The UDP header is automatically built by this routine. It uses the parameters OpFlags, DestIp, DestPort, GatewayIp, SrcIp, and SrcPort to build this header. If the packet is successfully built and transmitted through the network interface, then EFI_SUCCESS will be returned. If a timeout occurs during the transmission of the packet, then EFI_TIMEOUT will be returned. If an ICMP error occurs during the transmission of the packet, then the IcmpErrorReceived field is set to TRUE, the IcmpError field is filled in and EFI_ICMP_ERROR will be returned. If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then EFI_ABORTED will be returned.
