I still don't like it, sorry, not just for your patch, I never like
cls_bpf either, in terms of the user interface and the duplicated
functionalities: cls_bpf vs u32, act_bpf vs gact.

Ideally we should be able to implement them with the same
interface, transparent to users, I think probably because
the nature of bpf implementation somewhat enforces such
interface everywhere, it is clearly overrated.

(I have no idea about eBPF though.)
