Subject: [dpdk-dev] [PATCH 2/2] net/mlx5: avoid unbind step to enable switchdev mode
Date: Mon, 15 Mar 2021 15:33:58 +0000
Message-ID: <1615822438-10082-2-git-send-email-iviktorin@fit.vutbr.cz> (raw)
In-Reply-To: <1615822438-10082-1-git-send-email-iviktorin@fit.vutbr.cz>

From: Jan Viktorin <viktorin@cesnet.cz>

The step 4 is a contradiction. It advices to unbind the device from the
mlx5_core which removes the associated system network interface (e.g.
eth0). In the step 5, the same system network interface (e.g. eth0) is
required to exist.
