* LWIP_VLAN_PCP==1: Enable outgoing VLAN taggning of frames on a per-PCB basis
* for QoS purposes. With this feature enabled, each PCB has a new variable: "tci".
* (Tag Control Identifier). The TCI contains three fields: VID, CFI and PCP.
* VID is the VLAN ID, which should be set to zero.
* The "CFI" bit is used to enable or disable VLAN tags for the PCB.
* PCP (Priority Code Point) is a 3 bit field used for Ethernet level QoS.
