The ingress DSCP is composed of ingress-dscp10 (most significant digit in the left
column) and ingress-dscp1 (least significant digit in the top row (in other words,
ingress-dscp = ingress-dscp10 * 10 + ingress-dscp1); and the corresponding internal-
dscp is shown at the intersecting cell in the table.
The ingress DSCP is bitwise ANDed with the binary value 11 to determine the drop
precedence. If the resulting value is 10 binary, then the drop precedence is set to 0.
