3.2.82-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Yishai Hadas <yishaih@xxxxxxxxxxxx>
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")
