Subject: [PATCH AUTOSEL 5.7 28/53] ibmvnic: continue to init in CRQ reset returns H_CLOSED
Date: Wed, 1 Jul 2020 21:21:37 -0400 [thread overview]
Message-ID: <20200702012202.2700645-28-sashal@kernel.org> (raw)
In-Reply-To: <20200702012202.2700645-1-sashal@kernel.org>
From: Dany Madden <drt@linux.ibm.com>
[ Upstream commit 8b40eb73509f5704a0e8cd25de0163876299f1a7 ]
Continue the reset path when partner adapter is not ready or H_CLOSED is
returned from reset crq. This patch allows the CRQ init to proceed to
establish a valid CRQ for traffic to flow after reset.
