Ok, will do.  What do you want to do with the current series of patches
(mainly the ixgbe LER patches) on my tree?  I know that there is a
thread going on between Joe Perches and Mark, but it sounded like Mark
is working on a follow-on patch to address Joe's concerns.

Guess I want to know if I leave my tree alone for you to pull or toss
the current pull request series and get the i40e series applied.

Cheers,
Jeff
