R/W
= 1, flow control may be asserted if the port’s
high priority receive rate is exceeded.
(To use this, differential receive rate control must
be on.)
= 0, flow control is not asserted if the port’s high
priority receive rate is exceeded.

R/W
= 1, will do transmit rate control on both high and
low priority packets based on the rate counters
defined by the high and low priority packets
respectively.
= 0, will do transmit rate control on any packets.
The rate counters defined in low priority will be
used.
