Subject: [PATCH AUTOSEL 5.0 055/317] scsi: qedi: Abort ep termination if offload not scheduled
Date: Wed, 22 May 2019 15:19:16 -0400	[thread overview]
Message-ID: <20190522192338.23715-55-sashal@kernel.org> (raw)
In-Reply-To: <20190522192338.23715-1-sashal@kernel.org>

From: Manish Rangankar <mrangankar@marvell.com>

[ Upstream commit f848bfd8e167210a29374e8a678892bed591684f ]

Sometimes during connection recovery when there is a failure to resolve
ARP, and offload connection was not issued, driver tries to flush pending
offload connection work which was not queued up.
