Subject: [PATCH net-next-2.6 0/2] bonding: ARP monitor changes

	Two patches for bonding; these apply to net-next-2.6.  I'm
particularly interested in comments and test reports on #1.

	1- Refactor ARP monitor for active-backup mode.  Split the current
monolithic function into three: inspection, commit, and probe.  Done
primarily to get RTNL semantics right for next patch.  That could have
been done via conditional locking (as miimon was), but this feels like a
cleaner solution.

	2- Add a "follow" option to fail_over_mac.  This causes the
bonding master to take the MAC of the first slave, but not program the
other slaves with that MAC address.  During failover, the MAC moves to the
new currently active slave.  For multiport devices that can't handle
having all ports set to the same MAC (but still want the benefits of the
bond's MAC not changing during failover).

	-J
