Bridge multicast update - 3

Added support for #dynamic max_number_of_ports parameter in #bridge #multicast #forward-unregistered configuration on ethernet module. This will enable to dynamically set the size of #member #egress #ports, #static #ports and #forbidden #ports listing for each bridge VLAN. This removes the static allocation of max size of member port listing and reduces the memory requirement for the member port list. The forward-unregistered port configuration will be either configured statically or dynamically via #MMRP protocol.
