Subject: [net 04/10] net/mlx5: E-Switch, Fix double allocation of acl flow counter
Date: Thu, 30 Sep 2021 16:14:55 -0700	[thread overview]
Message-ID: <20210930231501.39062-5-saeed@kernel.org> (raw)
In-Reply-To: <20210930231501.39062-1-saeed@kernel.org>

From: Moshe Shemesh <moshe@nvidia.com>

Flow counter is allocated in eswitch legacy acl setting functions
without checking if already allocated by previous setting. Add a check
to avoid such double allocation.

Fixes: 07bab9502641 ("net/mlx5: E-Switch, Refactor eswitch ingress acl codes")
Fixes: ea651a86d468 ("net/mlx5: E-Switch, Refactor eswitch egress acl codes")
