Subject: [PATCH net-next 4/6] net/mlx5: Lag, Enable Multiport E-Switch offloads on 8 ports LAG

From: Amir Tzin <amirtz@...dia.com>

Patch [1] added mlx5 driver support for 8 ports HCAs which are available
since ConnectX-8. Now that Multiport E-Switch is tested, we can enable
it by removing flag MLX5_LAG_MPESW_OFFLOADS_SUPPORTED_PORTS.
