Subject: [net-next 01/15] net/mlx5e: Free drop RQ in a dedicated function
Date: Tue, 1 Dec 2020 14:41:54 -0800 [thread overview]
Message-ID: <20201201224208.73295-2-saeedm@nvidia.com> (raw)
In-Reply-To: <20201201224208.73295-1-saeedm@nvidia.com>
From: Tariq Toukan <tariqt@nvidia.com>
The drop RQ has very limited objects to be freed, and differs
from regular RQs in the context that it is freed from.
Add a dedicated function for it, use it where needed, and remove
the drop_rq-specific checks in the generic function.
