Subject: [PATCH net-next 2/6] net/mlx5: Return ready to use ASO WQE
Date: Sun, 23 Oct 2022 20:22:54 +0300	[thread overview]
Message-ID: <081372b10853d727085470e1f389dd29ca29479f.1666545480.git.leonro@nvidia.com> (raw)
In-Reply-To: <cover.1666545480.git.leonro@nvidia.com>

From: Leon Romanovsky <leonro@nvidia.com>

There is no need in hiding returned ASO WQE type by providing void*,
use the real type instead. Do it together with zeroing that memory,
so ASO WQE will be ready to use immediately.
