I think patch 2 and 3 are way too large since igb and e1000e can be totally ioport
free at all times. There is no need to keep compatibility code for ioport in those
drivers as it's unlikely that this will ever be needed.

So, perhaps you can remove the ioport code from those 2 drivers (e1000e/igb)
completely and resubmit to Jeff Kirsher?

Cheers,

Auke
