Registers AVPML, AVPMM, and AVPMH allow the eight VLAN Tag priorities to map into eight Internal level transmit
priorities. Under the Internal transmit priority, seven is the highest priority where as zero is the lowest. This feature
allows the user the flexibility of redefining the VLAN priority field. For example, programming a value of 7 into bit 2:0
of the AVPML register would map packet VLAN priority 0 into Internal transmit priority 7. The new priority is used
inside the ZL50418. When the packet goes out it carries the original priority.
