Subject: [net-next V2 09/13] net/mlx5e: Generalize close RQ
Date: Thu, 25 Mar 2021 19:53:41 -0700 [thread overview]
Message-ID: <20210326025345.456475-10-saeed@kernel.org> (raw)
In-Reply-To: <20210326025345.456475-1-saeed@kernel.org>
From: Aya Levin <ayal@nvidia.com>
Allow different flavours of RQ to use the same close flow. Add validity
checks to support different RQ types which not necessarily initialize
all the RQ's functionality.
