Subject: [PATCH v4 1/7] net/mlx5/hws: fix bug in matcher disconnect error flow
Date: Thu, 6 Jun 2024 12:55:09 +0300 [thread overview]
Message-ID: <20240606095515.171170-2-mkashani@nvidia.com> (raw)
In-Reply-To: <20240606095515.171170-1-mkashani@nvidia.com>
From: Yevgeny Kliteynik <kliteyn@nvidia.com>
If error happens during disconnect of the first matcher in the
list, the matcher should be reconnected back as the first matcher.
