Subject: ethdev: add generic MAC address rewrite actions
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=15dbcdaada77;p=dpdk.git

ethdev: add generic MAC address rewrite actions

rte_flow actions:
- RTE_FLOW_ACTION_TYPE_SET_MAC_SRC
- RTE_FLOW_ACTION_TYPE_SET_MAC_DST
added in order to offload to NIC

The rte_flow_itme_eth must be present in rte_flow pattern
