Subject: [PATCH 5.10 14/29] qed: Fix the VF msix vectors flow
Date: Mon, 6 Sep 2021 14:55:29 +0200 [thread overview]
Message-ID: <20210906125450.263629480@linuxfoundation.org> (raw)
In-Reply-To: <20210906125449.756437409@linuxfoundation.org>
From: Shai Malin <smalin@marvell.com>
[ Upstream commit b0cd08537db8d2fbb227cdb2e5835209db295a24 ]
For VFs we should return with an error in case we didn't get the exact
number of msix vectors as we requested.
Not doing that will lead to a crash when starting queues for this VF.
