VID bits
Host Port default tag bits [11-0] for VID
Note: P3VIDCR serve two purposes:
(1) Associated with the ingress untagged packets, and used for egress tagging.
(2) Default VID for the ingress untagged or null-VID-tagged packets, and used for address look up.

Ingress Limit Mode
These bits determine what kinds of frames are limited and
counted against Ingress limiting as follows:
00 = Limit and count all frames
01 = Limit and count Broadcast, Multicast, and flooded
unicast frames
10 = Limit and count Broadcast and Multicast frames only
11 = Limit and count Broadcast frames only

RW
Count IFG bytes
1 = each frame’s minimum inter frame gap (IFG) bytes (12
per frame) are included in Ingress and Egress rate limiting
calculations.
0 = IFG bytes are not counted
0
RW
Count Preamble bytes
1 = each frame’s preamble bytes (8 per frame) are included
in Ingress and Egress rate limiting calculations.
0 = preamble bytes are not counted
