4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eran Ben Elisha <era...@mellanox.com>
commit 0bb9fc4f5429ac970181c073aa32e521e20f7b73 upstream.
The field res_free indicates the total number of counters which are
available for allocation (reserved and unreserved). Fixed a bug where
the reserved counters were subtracted from res_free before any
allocation was performed.
Before this fix, free counters which were not reserved could not be
allocated.
Fixes: 9de92c60beaa ("net/mlx4_core: Adjust counter grant policy in the
resource tracker")
