Subject: [dpdk-dev] [PATCH 3/4] net/mlx5: fix Tx stats error counter logic
Date: Wed, 13 Sep 2017 13:47:55 +0300 [thread overview]
Message-ID: <20170913104756.129102-3-shahafs@mellanox.com> (raw)
Tx error counter lacks the logic of incrementation, making it useless for
applications.
Fixes: 87011737b715 ("mlx5: add software counters")
