I didn't want to sign off for you b/c I reworded
the log.  I was trying to credit you for the patch
by stating you Authored it.  My apologies if that was
incorrect.

Yes, but didn't see it in Linus' git tree.
Should I have used one of Bjorn's tree/branch with
this patch in it as master of these patches ?

if bjorn could give Acked-by, those pci change patches go together
with ixgbe changes via Dave's Net-next tree.

or bjorn add one branch in pci next tree to have the first 4 patches,
and let Dave to pull it and use as base for ixgbe change.

or just first 4 patches go into 3.7 directly...
