VLAN1 Tag Identifier (VTI1)
This field contains the VLAN Tag used to identify VLAN1 frames. This field
is compared with the 13th and 14th bytes of the incoming frames for VLAN1
frame detection.
Note:
Host MAC VLAN1 Tag Register (HMAC_VLAN1)
This read/write register contains the VLAN tag field to identify VLAN1 frames. When a VLAN1 frame
is detected, the legal frame length is increased from 1518 bytes to 1522 bytes. Refer to
"Virtual Local Area Network (VLAN) Support," on page 114
If used, this register is typically set to the standard VLAN value of
8100h.
