[dpdk-dev] [PATCH v5 1/2] app/testpmd: add commands to test new Rx offload API

[Wei Dai <wei.dai@intel.com>]

Add following testpmd run-time commands to support test of
new Rx offload API:
rx_offload get capability <port_id>
rx_offload get configuration <port_id>
rx_offload enable|disable per_port <offload> <port_id>
rx_offload enable|disable per_queue <offload> <port_id> <queue_id>

Above last 2 commands should be run when the port is stopped.
And <offload> can be one of "vlan_strip", "ipv4_cksum", ...
