BITS
DESCRIPTION
2 Use Precedence
When the priority is taken from an IPV4 packet (enabled via the Use IP bit),
this bit selects between precedence bits in the TOS octet or the DIFFSERV
table.
When set, IPv4 packets will use the precedence bits in the TOS octet to
select the transmit priority queue. When cleared, IPv4 packets will use the
DIFFSERV table to select the transmit priority queue.
1 VL Higher Priority
When this bit is set and VLAN priority is enabled (via the Use Tag bit), the
priority from the VLAN tag has higher priority than the IP TOS/SC field.
0 VLAN Enable
When set, VLAN ingress rules are enabled.
