It may be better to split the series and send this patch to net,
the netdev CI has a netdevsim test for the prog offload, would be
good to run that.  

Though for now bpf_xdp_link_update() already does:

     if (old_prog->type != new_prog->type ||
         old_prog->expected_attach_type != new_prog->expected_attach_type) {
         err = -EINVAL;
         goto out_unlock;
     }

so the other checks can't be triggered on the update path even without 
them in dev_xdp_install().

So I'm thinking this patch works as a standalone fix (good for 
backport), and the cleanup goes as a followup (if necessary)?

Just do it right please. Feels like we are promised a follow up to
every single patch these days :/
