====================
net: Remove UDP Fragmentation Offload support

This is a patch series, based upon some discussions with various
developers, that removes UFO offloading.

Very few devices support this operation, it's usefullness is
quesitonable at best, and it adds a non-trivial amount of
complexity to our data paths.

v2: Delete more code thanks to feedback from Willem.
