[PATCH V3 net-next 05/14] net/ena: fix RSS default hash configuration

From: Netanel Belgazal
Date: Thu Jan 26 2017 - 17:21:44 EST


ENA default hash configures IPv4_frag hash twice instead of
configure non-IP packets.

The bug caused IPv4 fragmented packets to be calculated based on
L2 source and destination address instead of L3 source and destination.
IPv4 packets can reach to the wrong Rx queue.
