[PATCH net-next] net/mlx5e: Allow setting MAC address of representors

[PATCH net-next] net/mlx5e: Allow setting MAC address of representors

[Tariq Toukan]

From: Mark Bloch <mbloch@nvidia.com>

A representor netdev does not correspond to real hardware that needs to
be updated when setting the MAC address. The default eth_mac_addr() is
sufficient for simply updating the netdev's MAC address with validation.

Thanks.

I note that this is consistent with at least nfp_repr_netdev_ops.
