Hiroshi, I tried to apply your patches to my queue but they do not apply
cleanly and they are in a DOS file format, not UNIX.  I also noted
several checkpatch.pl issues with your patches, so please fix those up
as well.

Can you please fix up your patches based on my tree:
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/queue.git

This my queue of all community patches against the Intel LAN drivers and
will be where I queue up your patches while they are under review and
testing.
