Unicast congest threshold
Bit [7:0] :
Number of frame count. Used for best effort dropping at B% when
destination port’s best effort queue reaches UCC threshold and shared
pool is all in use. Granularity 1 frame. (Default: h10 for 2 MB or h08 for
1 MB)

0
FC reaction prd
Multicast congest threshold
Bit [4:0]:
In multiples of two. Used for triggering MC flow control when
destination multicast port’s best effort queue reaches MCC threshold.
(Default 0x10)
Bit [7:5]:
Flow control reaction period (Default 2) Granularity 4 uSec.

0
Buffer low thd
SP Buffer reservation
Bit [3:0]:
Per port buffer reservation.
Define the space in the FDB reserved for each 10/100 port. Expressed
in multiples of 4 packets. For each packet 1536 bytes are reserved in
the memory.
Bits [7:4]:
Expressed in multiples of 4 packets. Threshold for dropping all best
effort frames when destination port best efforts queues reach UCC
threshold and shared pool all used and source port reservation is at or
below the PR100[7:4] level. Also the threshold for initiating UC flow
control.
Default:
h58 for configuration with 2 MB;
h35 for configuration with 1 MB;
