This series tries to fixes several issues for virtio-net XDP which
could be categorized into several parts:

- fix several issues during XDP linearizing
- allow csumed packet to work for XDP_PASS
- make EWMA rxbuf size estimation works for XDP
- forbid XDP when GUEST_UFO is support
- remove big packet XDP support
- add XDP support or small buffer

Please see individual patches for details.

Thanks a lot Jason. The last piece that is needed is support to
complete XDP support is to get the adjust_head part correct. I'll
send out a patch in a bit but will need to merge it on top of this
set.
