 * Functions to manage the set of filtered Multicast MAC addresses.

 * A pool of filtered multicast MAC addresses is associated with each port.
 * The pool is allocated in chunks of MCAST_POOL_INC multicast addresses.
 * The address of the pool and the number of valid multicast MAC addresses
 * recorded in the pool are stored in the fields "mc_addr_pool" and
 * "mc_addr_nb" of the "rte_port" data structure.
 *
 * The function "rte_eth_dev_set_mc_addr_list" of the PMDs API imposes
 * to be supplied a contiguous array of multicast MAC addresses.
 * To comply with this constraint, the set of multicast addresses recorded
 * into the pool are systematically compacted at the beginning of the pool.
 * Hence, when a multicast address is removed from the pool, all following
 * addresses, if any, are copied back to keep the set contiguous.
