net/mlx4_core: Use both physical ports to dispatch link state events to VF
Under HA mode, the link down event should be sent to VFs only if both ports are down. Signed-off-by: Moni Shoua <monis@mellanox.com> Reviewed-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
