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.

@param[in] This Points to the EFI_VLAN_CONFIG_PROTOCOL.
|
|
@param[in] VlanId A unique identifier (1-4094) of the VLAN which is being created

|
or modified, or zero (0).
|

@param[in] Priority 3 bit priority in VLAN header. Priority 0 is default value. If
|
|
VlanId is zero (0), Priority is ignored.
