Ethernet MAC VLAN Tag (EMACVLANTG)
The Ethernet MAC VLAN Tag (MACVLANTG) register contains the IEEE 802.1Q VLAN Tag to identify the VLAN frames. The MAC compares the 13th and 14th bytes of the receiving frame (Length/Type) with the value 0x8100, and the following two bytes are compared with the VLAN tag. If a match occurs, the MAC sets the received VLAN bit in the receive frame status. The legal length of the frame is increased from 1518 bytes to 1522 bytes.
EMACVLANTG is shown in Figure 15-23 and described in Table 15-32.
