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)
- 000 Transmit Priority Level 0 (Lowest)
- 001 Transmit Priority Level 1
- 010 Transmit Priority Level 2
- 011 Transmit Priority Level 3

Fixed Discard priority (Default 0)
- 0 - Discard Priority Level 0 (Lowest)
- 1 - Discard Priority Level 7(Highest)
Enable Fix Priority (Default 0)
- 0 Disable fix priority. All frames are analysed. Transmit Priority and Drop Priority are based on
