I understand the theory and testing will need to bear that out. There is
a bit of distance (code wise) between where the program is run now and
where you want to put it - the conversion from xdp_buff
to xdp_frame, the enqueue, and what it means to do a redirect to another
device in bq_xmit_all.
More importantly though for a redirect is the current xdp_ok_fwd_dev
check in __xdp_enqueue which for a redirect could be doing the wrong
checks for the wrong device.
