Subject: [net-next 01/15] net/mlx5e: Enforce minimum value check for ICOSQ size
Date: Wed, 24 Mar 2021 22:04:24 -0700 [thread overview]
Message-ID: <20210325050438.261511-2-saeed@kernel.org> (raw)
In-Reply-To: <20210325050438.261511-1-saeed@kernel.org>
From: Tariq Toukan <tariqt@nvidia•com>
The ICOSQ size should not go below MLX5E_PARAMS_MINIMUM_LOG_SQ_SIZE.
Enforce this where it's missing.
