Description
These bits along with port control 9, bits [7:0] form a 12-bits
field to determine how many “32Kbps” low priority blocks can
be received. (in a unit of 4K bytes in a one second period)
These bits along with port control 8, bits [7:0] form a 12-bits
field to determine how many “32Kbps” high priority blocks can
be received. (in a unit of 4K bytes in a one second period)
Description
= 1, If bit 6 is also ‘1’, this will enable receive rate control for
high
= 0, receive rate control will be based on the low priority rate
= 1, enable port’s low priority receive rate control feature
= 0, disable port’s low priority receive rate control feature
= 1, If bit 7 is also ‘1’, this will enable the
priority receive rate control feature. If bit 7 is a ‘0’ and bit 6 is
a
= 0, disable port’s high priority receive rate control feature
= 1, flow control may be asserted if the port’s low priority
= 0, flow control is not asserted if the port’s low priority receive
= 1, flow control may be asserted if the port’s high priority
= 0, flow control is not asserted if the port’s high priority
= 1, will do transmit rate control on both high and low priority
= 0, will do transmit rate control on any packets. The rate
= 1, enable the port’s low priority transmit rate control feature
= 0, disable the port’s low priority transmit rate control feature
= 1, enable the port’s high priority transmit rate control feature
= 0, disable the port’s high priority transmit rate control feature
this port on low priority packets at the low priority rate. If
bit 5 is also ‘1’, this will enable receive rate control on
for all packets on this port.
‘1’, all receive packets on this port will be rate controlled
at the low priority rate.

packets based on the rate counters defined by the high
and low priority packets respectively.
counters defined in low priority will be used.
