Please CC e1000-devel and intel-wired-lan mailing lists, so that all the appropriate developers have a chance to review/respond. Especially if the person you are emailing is out or on vacation, you can get a quicker response by CC'ing the mailing lists as well. I have gone ahead and CC'd the appropriate mailing lists for you.
