Thanks a million for taking a look at these, Tony!

These driver patches are all independent and have no dependency on the
1/9 PCI/AER patch.  What's your opinion on merging these?  Should they
go via netdev?  Should they be squashed into a single patch that does
all the Intel drivers at once?

I'm happy to squash them and/or merge them via the PCI tree, whatever
is easiest.
