Hmm, I'm not sure how that got past our testing even after I asked to check for
redundant instances of "e1000e".  This patch can be dropped and I will submit an
updated one but it will still have the "must follow this format for user tools" comment
since the user tools key off of "e1000e: <iface> NIC Link is ..." text.

Thanks,
Bruce.
