Subject: [PATCH AUTOSEL 5.6 42/47] net/mlx5e: Update netdev txq on completions during closure
Date: Thu, 28 May 2020 07:55:55 -0400	[thread overview]
Message-ID: <20200528115600.1405808-42-sashal@kernel.org> (raw)
In-Reply-To: <20200528115600.1405808-1-sashal@kernel.org>

From: Moshe Shemesh <moshe@mellanox.com>

[ Upstream commit 5e911e2c06bd8c17df29147a5e2d4b17fafda024 ]

On sq closure when we free its descriptors, we should also update netdev
txq on completions which would not arrive. Otherwise if we reopen sqs
and attach them back, for example on fw fatal recovery flow, we may get
tx timeout.

Fixes: 29429f3300a3 ("net/mlx5e: Timeout if SQ doesn't flush during close")
