Function Documentation

Tcp6RefreshNeighbor()

EFI_STATUS Tcp6RefreshNeighbor	(	IN TCP_CB *	Tcb,
		IN EFI_IP_ADDRESS *	Neighbor,
		IN UINT32	Timeout
	)

Refresh the remote peer's Neighbor Cache State if already exists.

Parameters

[in]	Tcb	Pointer to the TCP_CB of this TCP instance.
[in]	Neighbor	Source address of the TCP segment.
[in]	Timeout	Time in 100-ns units that this entry will remain in the neighbor cache. A value of zero means that the entry is permanent. A value of non-zero means that the entry is dynamic and will be deleted after Timeout.

Return values

EFI_SUCCESS	Successfully updated the neighbor relationship.
EFI_NOT_STARTED	The IpIo is not configured.
EFI_INVALID_PARAMETER	Any input parameter is invalid.
EFI_OUT_OF_RESOURCES	Failed to allocate some resources.
EFI_NOT_FOUND	This entry is not in the neighbor table.

TcpRxCallback()

VOID EFIAPI TcpRxCallback	(	IN EFI_STATUS	Status,
		IN UINT8	IcmpErr,
		IN EFI_NET_SESSION_DATA *	NetSession,
		IN NET_BUF *	Pkt,
		IN VOID *Context	OPTIONAL
	)

Packet receive callback function provided to IP_IO, used to call the proper function to handle the packet received by IP.

Parameters

[in]	Status	Result of the receive request.
[in]	IcmpErr	Valid when Status is EFI_ICMP_ERROR.
[in]	NetSession	The IP session for the received packet.
[in]	Pkt	Packet received.
[in]	Context	The data provided by the user for the received packet when the callback is registered in IP_IO_OPEN_DATA::RcvdContext. This is an optional parameter that may be NULL.

TcpSendIpPacket()

INTN TcpSendIpPacket	(	IN TCP_CB *	Tcb,
		IN NET_BUF *	Nbuf,
		IN EFI_IP_ADDRESS *	Src,
		IN EFI_IP_ADDRESS *	Dest,
		IN UINT8	Version
	)

Send the segment to IP via IpIo function.

Parameters

[in]	Tcb	Pointer to the TCP_CB of this TCP instance.
[in]	Nbuf	Pointer to the TCP segment to be sent.
[in]	Src	Source address of the TCP segment.
[in]	Dest	Destination address of the TCP segment.
[in]	Version	IP_VERSION_4 or IP_VERSION_6

Return values

0	The segment was sent out successfully.
-1	The segment failed to send.
