This reminds me, since we allowed native/driver and offloaded XDP
programs to coexist in a25717d2b604 ("xdp: support simultaneous
driver and hw XDP attachment") I got an internal feature request
to also allow generic and native mode. Would anyone object to that?
Apart from a touch up to test_offload.py I don't think anything
would care. netlink can already carry multiple IDs, iproute2
understands it, too..
(Obviously as a follow up after this set gets merged.)
