Description
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.
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.
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.
Description
1, disable auto-negotiation, speed and duplex are
decided by bit 6 and 5 of the same register.
0, auto-negotiation is on.
1, forced 100BT if AN is disabled (bit 7).
0, forced 10BT if AN is disabled (bit 7).
1, forced full-duplex if (1) AN is disabled or (2) AN is
enabled but failed.
0, forced half-duplex if (1) AN is disabled or (2) AN is
enabled but failed.
1, advertise flow control capability.
0, suppress flow control capability from transmission
to link partner.
1, advertise 100BT full-duplex capability.
0, suppress 100BT full-duplex capability from
transmission to link partner.
1, advertise 100BT half-duplex capability.
0, suppress 100BT half-duplex capability from
transmission to link partner.
1, advertise 10BT full-duplex capability.
0, suppress 10BT full-duplex capability from
transmission to link partner.
