	My main problem keeping up at the moment is another demand on my
time that should run its course in a couple of weeks.  My time for
community activity is somewhat limited until then.

	As far as the features go, yes, I agree that things are getting
out of hand.  The two pending patches for special cases related to
802.3ad (Oleg's patch to permit round robining, the other to enable
spanning aggregators across switches), for example, are fine
functionality, but there really needs to be a better, generic, way to do
this sort of niche case activity without adding more knobs.

	I personally like Stephen's suggestion to hook bonding into a
netfilter gadget, similar to ebtables for bridge.  Done properly, such a
gadget should handle (or be extended to handle) the niche cases that
right now end up as new knobs in the driver.

	What did you have in mind here?
