Matt Macy b6f6f88018 r333175 introduced deferred deletion of multicast addresses in order to permit the driver ioctl ... to sleep on commands to the NIC when updating multicast filters. More generally this permitted driver's to use an sx as a softc lock. Unfortunately this change introduced a race whereby a a multicast update would still be queued for deletion when ifconfig deleted the interface thus calling down in to _purgemaddrs and synchronously deleting _all_ of the multicast addresses on the interface. Synchronously remove all external references to a multicast address before enqueueing for delete. Reported by: lwhsu Approved by: sbruno		2018-05-06 20:34:13 +00:00
