Subject: examples/eventdev: add new Rx RSS hash offload
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=4c634d7392fa7f330896544e2ca88a93b0d06d80;p=dpdk.git

examples/eventdev: add new Rx RSS hash offload

Since pipeline_generic uses `rte_mbuf::hash::rss` add the new Rx offload
flag `DEV_RX_OFFLOAD_RSS_HASH` to inform PMD to copy the RSS hash result
into the mbuf.
