    team: no need to do team_notify_peers or team_mcast_rejoin when disabling port · 5ed9dc99
    Hangbin Liu authored
    team_notify_peers() will send ARP and NA to notify peers. team_mcast_rejoin()
    will send multicast join group message to notify peers. We should do this when
    enabling/changed to a new port. But it doesn't make sense to do it when a port
    is disabled.
    
    On the other hand, when we set mcast_rejoin_count to 2, and do a failover,
    team_port_disable() will increase mcast_rejoin.count_pending to 2 and then
    team_port_enable() will increase mcast_rejoin.count_pending to 4. We will send
    4 mcast rejoin messages at latest, which will make user confused. The same
    with notify_peers.count.
    
    Fix it by deleting team_notify_peers() and team_mcast_rejoin() in
    team_port_disable().
