Subject: [PATCH 3.12 063/142] net/mlx5: Increase number of max QPs in default profile

From: Maor Gottlieb <maorg@...lanox.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

[ Upstream commit 5f40b4ed975c26016cf41953b7510fe90718e21c ]

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.

[js] this is in another file in 3.12
