+ 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.
+
+ @retval EFI_SUCCESS The VLAN is successfully configured.

+ - This is NULL.
+ - VlanId is an invalid VLAN Identifier.
+ - Priority is invalid.
+ @retval EFI_OUT_OF_RESOURCES There is not enough system memory to perform the registration.
