	If I'm reading the above correctly, then this type selection is
only needed for Red Hat 4 (or, really, versions of bonding prior to when
the bonding master started to set its carrier state based upon the state
of the slaves), correct?

	If that's the case, then is this patch is fixing a problem that
doesn't exist in the mainline?  If this isn't a problem with the current
driver (where "current" here seems to be bonding 3.0.3 and later, which
is about two years old), I don't see why it should go into the mainline.

	Am I misunderstanding something?
