Subject: [PATCH AUTOSEL 4.14 06/13] qede: fix offload for IPIP tunnel packets
From: Manish Chopra <manishc@...vell.com>
[ Upstream commit 5d5647dad259bb416fd5d3d87012760386d97530 ]
IPIP tunnels packets are unknown to device,
hence these packets are incorrectly parsed and
caused the packet corruption, so disable offlods
for such packets at run time.
