After some discussion, it sounds like the problem here is that this patch 
fixes a bug in a workaround for other serious problems -- i.e., that when 
you reset the interface to deal with the fact that the interface has 
wedged, it isn't being properly reset.  So this patch is useful, in that 
it helps work around one or more other serious bugs better, but still 
leaves serious underlying problems.  That said, I think it would be good 
to MFC the fix.
