If SK is unable to help you, I don't think posting to the list will add much to this.
Also, please do not start asking random people whose email addresses you have. The issue will have to circle back to the appropriate AEs for disposition.

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. ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
