xdp: propagate extended ack to XDP setup
Drivers usually have a number of restrictions for running XDP - most common being buffer sizes, LRO and number of rings. Even though some drivers try to be helpful and print error messages experience shows that users don't often consult kernel logs on netlink errors. Try to use the new extended ack mechanism to carry the message back to user space. Signed-off-by:Jakub Kicinski <jakub.kicinski@netronome.com> Acked-by:
