This broadcast and multicast rate defines for each port, the number of packets allowed to be forwarded within a
specified time. Once the packet rate is reached, packets will be dropped. To turn off the rate limit, program the field
to 0. Time base is based on register FCR [6:4]

Multicast Rate Control. Number of multicast packets allowed within the time
defined in bits 6 to 4 of the Flooding Control Register (FCR). (Default 0) .
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)
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)
