Subject: [PATCH AUTOSEL 4.14 36/36] qed: Consider TX tcs while deriving the max num_queues for PF.
Date: Thu, 28 Feb 2019 10:13:37 -0500 [thread overview]
Message-ID: <20190228151337.12176-36-sashal@kernel.org> (raw)
In-Reply-To: <20190228151337.12176-1-sashal@kernel.org>
From: Sudarsana Reddy Kalluru <skalluru@marvell.com>
[ Upstream commit fb1faab74ddef9ec2d841d54e5d0912a097b3abe ]
Max supported queues is derived incorrectly in the case of multi-CoS.
Need to consider TCs while calculating num_queues for PF.
