Subject: [net-next 05/16] net/mlx5: DR, Add check for flex parser ID value
Date: Tue, 28 Dec 2021 22:24:51 -0800 [thread overview]
Message-ID: <20211229062502.24111-6-saeed@kernel.org> (raw)
In-Reply-To: <20211229062502.24111-1-saeed@kernel.org>
From: Yevgeny Kliteynik <kliteyn@nvidia.com>
Allow only legal values for flex parser ID - values from 0 to 7.
For other values skip the parser, and as a result the matcher creation
will fail for using invalid flex parser ID.
