Subject[PATCH 4.14 313/496] qede: Do not drop rx-checksum invalidated packets.
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Manish Chopra <manish.chopra@cavium.com>

[ Upstream commit 58f101bf87e32753342a6924772c6ebb0fbde24a ]

Today, driver drops received packets which are indicated as
invalid checksum by the device. Instead of dropping such packets,
pass them to the stack with CHECKSUM_NONE indication in skb.
