[dpdk-dev] [PATCH 1/2] net/sfc: fix RSS hash flag when offload is disabled

[Andrew Rybchenko]

From: Igor Romanov <igor.romanov at oktetlabs.ru>

Do not set RSS hash flag in the received mbufs when RSS hash
offload is not enabled, which means that RSS hash value is invalid.

Fixes: 5d308972954c ("ethdev: add mbuf RSS update as an offload")
