Subject: [net 4/6] net/mlx5e: Fix return value from timeout recover function
Date: Thu, 11 Jul 2019 18:54:16 +0000	[thread overview]
Message-ID: <20190711185353.5715-5-saeedm@mellanox.com> (raw)
In-Reply-To: <20190711185353.5715-1-saeedm@mellanox.com>

From: Aya Levin <ayal@mellanox.com>

Fix timeout recover function to return a meaningful return value.
When an interrupt was not sent by the FW, return IO error instead of
'true'.

Fixes: c7981bea48fb ("net/mlx5e: Fix return status of TX reporter timeout recover")
