Committed By:   knakahara
Date:           Thu Dec  1 02:30:54 UTC 2016

Modified Files:
        src/sys/net: if_spppsubr.c if_spppvar.h

Log Message:
fix two races between set_ip_addrs and clear_ip_addrs race.

    (1) if set_ip_addrs and clear_ip_addrs run parallel, they can parallel call
        IN_ADDRHASH_WRITER_REMOVE to the same ifa.
    (2) if set_ip_addrs's workqueue is separated from clear_ip_addrs's one,
        the workers can run in reverse order of enqueued.
