Subject: [net-next 10/13] net/mlx5: Allow co-enablement of uplink LAG and SRIOV

From: Rabie Loulou <rabiel@...lanox.com>

Enable setting uplink LAG if sriov is enabled on both ports in switchdev
mode.

Once the sriov mode is changed from switchdev for any of the ports, the
LAG instance is disabled.
