Subject: [PATCH for-next] IB/mlx5: Fix port counter ID association to QP offset
Date: Wed, 13 Jul 2016 16:25:11 +0300	[thread overview]
Message-ID: <1468416311-25643-1-git-send-email-leon@kernel.org> (raw)

From: Alex Vesker <valex-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

The q-counter-id is given in modify-QP command associates
the QP with the counter. The offset to which the counter
ID was set is incorrect, causing IB port counters not to
count on QP.

Fixes: 0837e86a7a34 ('IB/mlx5: Add per port counters')
