[PATCH 3.16 080/178] net/mlx5: Increase number of max QPs in default profile

From: Ben Hutchings
Date: Sun Jul 16 2017 - 10:04:45 EST


3.16.46-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Maor Gottlieb <maorg@xxxxxxxxxxxx>

commit 5f40b4ed975c26016cf41953b7510fe90718e21c upstream.

With ConnectX-4 sharing SRQs from the same space as QPs, we hit a
limit preventing some applications to allocate needed QPs amount.
Double the size to 256K.

Fixes: e126ba97dba9e ('mlx5: Add driver for Mellanox Connect-IB adapters')
