Subject: [PATCH net-next v2 6/7] net/mlx5e: Move devlink port register and unregister calls
Date:   Fri,  3 Jul 2020 06:27:37 +0300
Message-Id: <1593746858-6548-7-git-send-email-moshe@mellanox.com>
In-Reply-To: <1593746858-6548-1-git-send-email-moshe@mellanox.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Vladyslav Tarasiuk <vladyslavt@mellanox.com>

Register devlink ports upon NIC init. TX and RX health reporters handle
errors which may occur early on at driver initialization. And because
these reporters are to be moved to port context, they require devlink
ports to be already registered.
