Bits [7:4]:
Expressed in multiples of 4 packets. Threshold for dropping all best effort
frames when destination port best efforts queues reaches UCC threshold,
shared pool is all used and source port reservation is at or below the
PR100[7:4] level. Also the threshold for initiating UC flow control.
Default:
- h36 for 24+2 configuration with memory 2 MB/bank;
- h24 for 24+2 configuration with 1MB/bank;

Buffer low threshold
SP buffer reservation
Bit [3:0]:
Per source port buffer reservation.
Define the space in the FDB reserved for each Gigabit port. Expressed in
multiples of 16 packets. For each packet 1536 bytes are reserved in the
memory.
