Subject: [net-next 15/15] net/mlx5: Enable 4 ports multiport E-switch
Date: Tue, 19 Sep 2023 23:35:52 -0700 [thread overview]
Message-ID: <20230920063552.296978-16-saeed@kernel.org> (raw)
In-Reply-To: <20230920063552.296978-1-saeed@kernel.org>
From: Shay Drory <shayd@nvidia.com>
enable_mpesw() assumed only 2 ports are available, fix this by removing
that assumption and looping through the existing lag ports to enable multi-port
E-switch for cards with more than 2 ports.
