Drop Probability
These bits specify the discard probability of a packet that has been colored
Yellow by the ingress metering. The probability is given in 1/1024’s. For
example, a setting of 1 is one in 1024, or approximately 0.1%. A setting of
all ones (1023) is 1023 in 1024, or approximately 99.9%.
There are a total of 16 probability entries. Each entry corresponds to a range
of the number of buffers used by the ingress port, as specified in
13.3.4.10, "Buffer Manager Random Discard Table Command Register
(BM_RNDM_DSCRD_TBL_CMD)".
Buffer Manager Random Discard Table Read Data Register (BM_RNDM_DSCRD_TBL_RDATA)
This register is used to read the Random Discard Weight table.
