[RFC PATCH] virtio_net: XDP support for adjust_head
Add support for XDP adjust head by allocating a 256B header region
that XDP programs can grow into. This is only enabled when a XDP
program is loaded.
In order to ensure that we do not have to unwind queue headroom push
queue setup below bpf_prog_add. It reads better to do a prog ref
unwind vs another queue setup call.
TBD merge with Jason Wang's fixes, do a bit more testing, note
big_packet support is removed by Jason as well.
