/**\r
  Create a VLAN device or modify the configuration parameter of an\r

\r
  The Set() function is used to create a new VLAN device or change the VLAN\r
  configuration parameters. If the VlanId hasn't been configured in the\r
  physical Ethernet device, a new VLAN device will be created. If a VLAN with\r
  this VlanId is already configured, then related configuration will be updated\r
  as the input parameters.\r
\r
  If VlanId is zero, the VLAN device will send and receive untagged frames.\r
  Otherwise, the VLAN device will send and receive VLAN-tagged frames containing the VlanId.\r
  If VlanId is out of scope of (0-4094), EFI_INVALID_PARAMETER is returned.\r
  If Priority is out of the scope of (0-7), then EFI_INVALID_PARAMETER is returned.\r
  If there is not enough system memory to perform the registration, then\r
  EFI_OUT_OF_RESOURCES is returned.\r
