1) I find this kind of patches a real pain, frankly.

When I have to look around code and commits to find bugs and bugs
origins, I'll have to fully check this kind of patch, and this slow down
the process a _lot_, because I have no idea if "Joe Perches" actually
tested the patch, or if its yet another "code beautifier" process in the
wild.

You should have shooted when/before commit bfd5f4a3 (packet: Add
GSO/csum offload support) was accepted.

2) You did not CCed Sridhar Samudrala <sri@...ibm.com>, the author of
above commit. I dont think David will take the time to test your patch.

3) You add some non codingstyle artifacts. I am afraid it makes me
nervous for patches bringing no real values but shuffling the code and
making maintainers life more difficult.
