sys/net if_vlan.c
Log:
Workaround a locking problem in vlan(4). vlan_setmulti() may be called
with sleepable locks held from further up in the network stack, and
attempts to allocate memory to hold multicast group membership information
with M_WAITOK.
This panic was triggered specifically when an exiting routing daemon
process closes its raw sockets after joining multicast groups on them.
While we're here, comment some possible locking badness.
