This register indicates the legal egress ports. Example: A “1” on bit 3 means that packets arriving on port 0 can be
sent to port 3. A “0” on bit 3 means that any packet destined to port 3 will be discarded.

All packets transmitted from this port are untagged. This register is used when this port is
connected to legacy equipment that does not support VLAN tagging.
Bit [5:3]:
Fixed Transmit priority. Used when bit[7] = 1

(Default 0)
- 0 - Discard Priority Level 0 (Lowest)
- 1 - Discard Priority Level 7(Highest)
Bit [7]:
Enable Fix Priority
(Default 0)
- 0 Disable fix priority. All frames are analysed. Transmit Priority and Drop Priority are based on
VLAN Tag, TOS or Logical Port.
- 1 Transmit Priority and Discard Priority are based on values programmed in bit [6:3]
