Log Message:
eqos(4): Fix locking around multicast filter updates.
- Can't touch if_flags without IFNET_LOCK.
- Can't take IFNET_LOCK in SIOCADDMULTI/SIOCDELMULTI path.
Instead, cache IFF_PROMISC and IFF_ALLMULTI on if_init under a lock we
can take in this path.
XXX Is IFF_ALLMULTI relevant any more? Hasn't it been moved to
ethercom flags?
XXX Should not take sc_lock around if_init/stop -- IFNET_LOCK is
enough. Should narrow scope of sc_lock to be just tick/mii/multi
stuff.
