Bernard, a v3 is on the way.  I included only things that are fixes,
but the patch set doesn't quite match the set of patch numbers you listed
above.  1/6 (bond: use existing enslaved device queues) is an improvement,
but doesn't really fix anything that was broken, so I left that out.
2/6 (bond mode 4: copy entire config structure) and 3/6 (bond mode 4:
do not ignore multicast) fix bugs and are included.
