Change Details

This reverts commit fa03d37432caf17d56a931a9e6f5d9b06f102c5b. This commit caused us to not send IGMP leave messages if the inpcb went away. In other words: we freed pending packets whenever the socket closed rather than when the interface (or address) goes away. mcast: fix leaked igmp packets on multicast cleanup When we release a multicast address (e.g. on interface shutdown) we may still have packets queued in inm_scq. We have to free those, or we'll leak memory.

The commits below have not been added to stable/14. They have been known to break IGMP leave messages both on 14.0 and 14.1.
