Subject: [PATCH 3.14 37/46] IB/mlx4: Fix the SQ size of an RC QP
Date: Thu, 18 Aug 2016 15:54:59 +0200 [thread overview]
Message-ID: <20160818135447.917683792@linuxfoundation.org> (raw)
In-Reply-To: <20160818135442.457400364@linuxfoundation.org>
3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yishai Hadas <yishaih@mellanox.com>
commit f2940e2c76bb554a7fbdd28ca5b90904117a9e96 upstream.
When calculating the required size of an RC QP send queue, leave
enough space for masked atomic operations, which require more space than
"regular" atomic operation.
Fixes: 6fa8f719844b ("IB/mlx4: Add support for masked atomic operations")
