U2MR: Unicast to Multicast Rate. Units in terms of time base defined in bits
[6:4]. This is used to limit the amount of flooding traffic from Port n. The value
in U2MR specifies how many packets are allowed to flood within the time
specified by bit [6:4]. To disable this function, program U2MR to 0.
