Thanks for doing this! The patches look good to me.

A few minor nit picks I registered, IDK how hard we want to press 
on these:

 - it seems in couple places you remove the last user of DRV_RELDATE,
   but not the define. In case of bonding maybe we can remove the date
   too. IDK what value it brings in the description, other than perhaps
   humoring people;
 - we should probably give people a heads up by CCing maintainers
   (regardless of how dumb we find not bothering to read the ML as
   a maintainer);
 - one on the FW below..

These seem reasonable to me, although in abundance of caution it could
be a good idea to have them as separate commits so we can revert more
easily. Worse come to worst.
