-/*
- *	Linux NET3:	Multicast List maintenance.
- *
- *	Authors:
- *		Tim Kordas <tjk@nostromo.eeap.cwru.edu>
- *		Richard Underwood <richard@wuzz.demon.co.uk>
- *
- *	Stir fried together from the IP multicast and CAP patches above
- *		Alan Cox <alan@lxorguk.ukuu.org.uk>
- *
- *	Fixes:
- *		Alan Cox	:	Update the device on a real delete
- *					rather than any time but...
- *		Alan Cox	:	IFF_ALLMULTI support.
- *		Alan Cox	: 	New format set_multicast_list() calls.
- *		Gleb Natapov    :       Remove dev_mc_lock.

- *	Device multicast list maintenance.
- *
- *	This is used both by IP and by the user level maintenance functions.
- *	Unlike BSD we maintain a usage count on a given multicast address so
- *	that a casual user application can add/delete multicasts used by
- *	protocols without doing damage to the protocols when it deletes the
- *	entries. It also helps IP as it tracks overlapping maps.
- *
- *	Device mc lists are changed by bh at least if IPv6 is enabled,
- *	so that it must be bh protected.
- *
- *	We block accesses to device mc filters with netif_tx_lock.
