-Subject: ipv4: Don't do expensive useless work during inetdev destroy.
-Origin: https://git.kernel.org/linus/fbd40ea0180a2d328c5adc61414dc8bab9335ce2
-
-When an inetdev is destroyed, every address assigned to the interface
-is removed.  And in this scenerio we do two pointless things which can
-be very expensive if the number of assigned interfaces is large:
-
-1) Address promotion.  We are deleting all addresses, so there is no
-   point in doing this.
-
-2) A full nf conntrack table purge for every address.  We only need to
-   do this once, as is already caught by the existing
-   masq_dev_notifier so masq_inet_event() can skip this.
