When an interface is removed, all netlink events for that interface are lost, because netd will no longer be able to resolve the ifindex in the netlink event to an interface name, and it only communicates to the framework events that include an interface name. This can cause us to end up with stale IP addresses if, for example, wlan0 is removed because we switch wifi back from AP mode to STA mode when exiting tethering. The presence of stale IPv4 addresses can in turn lead us to miss a provisioning notification because we already think we have an IPv4 address. Change-Id: Ib64559a5a4fa261f483760b69fa7996314e7cc17
