EFI_VLAN_CONFIG_FIND

typedef EFI_STATUS(EFIAPI * EFI_VLAN_CONFIG_FIND) (IN EFI_VLAN_CONFIG_PROTOCOL *This, IN UINT16 *VlanId OPTIONAL, OUT UINT16 *NumberOfVlan, OUT EFI_VLAN_FIND_DATA **Entries)

Find configuration information for specified VLAN or all configured VLANs.

The Find() function is used to find the configuration information for matching VLAN and allocate a buffer into which those entries are copied.

Parameters

[in]	This	Points to the EFI_VLAN_CONFIG_PROTOCOL.
[in]	VlanId	Pointer to VLAN identifier. Set to NULL to find all configured VLANs.
[out]	NumberOfVlan	The number of VLANs which is found by the specified criteria.
[out]	Entries	The buffer which receive the VLAN configuration.

Return values

EFI_SUCCESS	The VLAN is successfully found.
EFI_INVALID_PARAMETER	One or more of following conditions is TRUE: This is NULL. Specified VlanId is invalid.
EFI_NOT_FOUND	No matching VLAN is found.

EFI_VLAN_CONFIG_REMOVE

typedef EFI_STATUS(EFIAPI * EFI_VLAN_CONFIG_REMOVE) (IN EFI_VLAN_CONFIG_PROTOCOL *This, IN UINT16 VlanId)

Remove the configured VLAN device.

The Remove() function is used to remove the specified VLAN device. If the VlanId is out of the scope of (0-4094), EFI_INVALID_PARAMETER is returned. If specified VLAN hasn't been previously configured, EFI_NOT_FOUND is returned.

Parameters

[in]	This	Points to the EFI_VLAN_CONFIG_PROTOCOL.
[in]	VlanId	Identifier (0-4094) of the VLAN to be removed.

Return values

EFI_SUCCESS	The VLAN is successfully removed.
EFI_INVALID_PARAMETER	One or more of following conditions is TRUE: This is NULL. VlanId is an invalid parameter.
EFI_NOT_FOUND	The to-be-removed VLAN does not exist.

EFI_VLAN_CONFIG_SET

typedef EFI_STATUS(EFIAPI * EFI_VLAN_CONFIG_SET) (IN EFI_VLAN_CONFIG_PROTOCOL *This, IN UINT16 VlanId, IN UINT8 Priority)

Create a VLAN device or modify the configuration parameter of an already-configured VLAN.

The Set() function is used to create a new VLAN device or change the VLAN configuration parameters. If the VlanId hasn't been configured in the physical Ethernet device, a new VLAN device will be created. If a VLAN with this VlanId is already configured, then related configuration will be updated as the input parameters.

If VlanId is zero, the VLAN device will send and receive untagged frames. Otherwise, the VLAN device will send and receive VLAN-tagged frames containing the VlanId. If VlanId is out of scope of (0-4094), EFI_INVALID_PARAMETER is returned. If Priority is out of the scope of (0-7), then EFI_INVALID_PARAMETER is returned. If there is not enough system memory to perform the registration, then EFI_OUT_OF_RESOURCES is returned.

Parameters

[in]	This	Points to the EFI_VLAN_CONFIG_PROTOCOL.
[in]	VlanId	A unique identifier (1-4094) of the VLAN which is being created or modified, or zero (0).
[in]	Priority	3 bit priority in VLAN header. Priority 0 is default value. If VlanId is zero (0), Priority is ignored.

Return values

EFI_SUCCESS	The VLAN is successfully configured.
EFI_INVALID_PARAMETER	One or more of following conditions is TRUE: This is NULL. VlanId is an invalid VLAN Identifier. Priority is invalid.
EFI_OUT_OF_RESOURCES	There is not enough system memory to perform the registration.
