Subject: [net 03/11] net/mlx5: DR, Fix wrong allocation of modify hdr pattern
Date: Mon, 7 Aug 2023 14:25:59 -0700 [thread overview]
Message-ID: <20230807212607.50883-4-saeed@kernel.org> (raw)
In-Reply-To: <20230807212607.50883-1-saeed@kernel.org>
From: Yevgeny Kliteynik <kliteyn@nvidia.com>
Fixing wrong calculation of the modify hdr pattern size,
where the previously calculated number would not be enough
to accommodate the required number of actions.
Fixes: da5d0027d666 ("net/mlx5: DR, Add cache for modify header pattern")
