[dpdk-dev] [PATCH 4/8] app/testpmd: parse map actions

[Bernard Iremonger <bernard.iremonger@intel.com>]

Parse map, pctype and flowtype on testpmd command line.

In cmdline_flow.c add the following:

ACTION_MAP
ACTION_MAP_PCTYPE
ACTION_MAP_FLOWTYPE
add parse_vc_action_map()

Update testpmd user guide with map action and
sample map action rules.
