Bit [7:4] :
Broadcast Rate Control. Number of broadcast packets allowed within the
time defined in bits 6 to 4 of the Flooding Control Register (FCR).
(Default
0)

0
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/bank or h08 for 1 MB/bank)

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

Buffer low threshold
SP Buffer reservation
Bit [3:0]:
Per source port buffer reservation.
Define the space in the FDB reserved for each 10/100 port and CPU.
Expressed in multiples of 4 packets. For each packet 1536 bytes are
reserved in the memory.
