#1410235 — [PATCH 5/5] ethernet: Use pci_(request|release)_mem_regions

Now that we do have pci_request_mem_regions() and pci_release_mem_regions() at
hand, use it in the ethernet drivers.

This should probably be one patch per driver.

I though if I do one patch per subsystem it'll be less a hassle for the
individual maintainers, but if the netdev people want it as split up, I'll be
doing it of cause.

Since almost all the changes are to Intel wired LAN drivers, if you just
split off the atheros change into a separate patch, I would be happy.  Then
you could keep just one patch to change all the Intel drivers.

That should be doable. I'll send a v2 with all requested changes tomorrow.
