I did some work in the not-too-distant past on this and can probably
dig-up the patches and port them to the latest upstream.  Would you be
able to test a patch?

It's a bit unclear to me why Jeff's patches were never accepted, but I
suspect if there were many that didn't like them before, they won't be
well received now, but it sure would be nice to use kgdb and use
netconsole on bonding interfaces, wouldn't it? :-)
