4.14-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 5ed9dc99107144f83b6c1bb52a69b58875baf540 ]
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().
