Priority Enable Vector
When the Remove FCS bit in the GMAC Network Configuration register (GMAC_NCFGR.RFCS) is written to '1', the priority enable vector of the PFC priority-based pause frame is set to the value stored in this bit field.
Pause Quantum
When the Remove FCS bit in the GMAC Network Configuration register (GMAC_NCFGR.RFCS) is written to '1', and one or more bits in this bit field are written to '0', the associated PFC pause frame's pause quantum field value is taken from the Transmit Pause Quantum register (GMAC_TPQ).
For each entry equal to '1' in this bit field, the pause quantum associated with that entry will be zero.
