Merge branch 'bpf-add-offload-as-a-first-class-citizen'

Jakub Kicinski says:

====================
bpf: add offload as a first class citizen

This series is my stab at what was discussed at a recent IOvisor
bi-weekly call.  The idea is to make the device translator run at
the program load time.  This makes the offload more explicit to
the user space.  It also makes it easy for the device translator
to insert information into the original verifier log.

v2:
 - include linux/bug.h instead of asm/bug.h;
 - rebased on top of Craig's verifier fix (no changes, the last patch
   just removes more code now).  I checked the set doesn't conflict
   with Jiri's, Josef's or Roman's patches, but missed Craig's fix :(
v1:
 - rename the ifindex member on load;
 - improve commit messages;
 - split nfp patches more.
====================
