__team_port_change_send() calls __ethtool_get_link_ksettings() on the port, which will soon take the port's ops lock. The notifier caller already holds it while the slave-add/del callers do not, so the function would either deadlock or run unprotected depending on the path. Make __team_port_change_send() expect the port's ops lock held and switch to netif_get_link_ksettings(). team_device_event()'s NETDEV_UP / NETDEV_CHANGE already arrive with the port's ops lock held. team_port_add() now take it explicitly. Note that NETDEV_DOWN and team_port_del() will pass false as @linkup so they will not execute netif_get_link_ksettings(). This is fortunate as NETDEV_DOWN has somewhat mixed locking right now.
