	If the patch actually fixed your problem, then your problem in
the first place had to do with the aggregation not forming correctly
(i.e., the links coming up individually, not as a set).  

	I think this is unlikely.  I think this because the 2.4 bonding
driver should already inspect the speed / duplex on each mii check (the
rate of which depends upon the miimon parameter value).  All the patch
does is additionally check the speed and duplex again when the system
notifies bonding that a slave's state has changed.

	Could you check a failing configuration again, and see if the
/proc/net/bonding/bond* shows that all of the slaves have the same
"aggregator ID," and that there is an active aggregator, and its
"partner MAC address" is not all zeroes?

	If the failing system shows all slaves with the same agg ID and
an active partner MAC, then I don't think this patch really fixed
anything, and something else changed that resolved the problem.

	I would appreciate it if you could check this, since if there is
an actual issue, I'll want to submit that patch to the stable 2.4
release (if it fixes an actual bug).
