Subject: [PATCH net 3/6] qed: Consider TX tcs while deriving the max num_queues for PF.
Date: Wed, 6 Feb 2019 14:43:44 -0800 [thread overview]
Message-ID: <20190206224347.17054-4-manishc@marvell.com> (raw)
In-Reply-To: <20190206224347.17054-1-manishc@marvell.com>
From: Sudarsana Reddy Kalluru <skalluru@marvell.com>
Max supported queues is derived incorrectly in the case of multi-CoS.
Need to consider TCs while calculating num_queues for PF.
