Dekel Peled 4a72909224 app/testpmd: set maximum LRO packet size 
This patch implements use of the API for LRO aggregated packet
max size.
It adds command-line and runtime commands to configure this value,
and adds option to show the supported value.
Documentation is updated accordingly.

* 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.

* To comply with this constraint, the set of multicast addresses recorded
