[dpdk-dev] [PATCH 02/15] net/softnic: rte flow attr mapping to pipeline

[Reshma Pattan <reshma.pattan@intel.com>]

Added mapping support from rte flow attributes
to softnic pipeline and table.

So added flow attribute map set and get functions
definition to new file rte_eth_sofnic_flow.c.

Added pmd flow internals with ingress and egress
flow attribute maps.
