Hi Kuba.

I'm looking into cls_bpf code and nfp_net_bpf_offload function in your
driver. Why do you need TC_CLSBPF_ADD? Seems like TC_CLSBPF_REPLACE
should be enough. It would make the cls_bpf code easier.

Note that other cls just have replace/destroy (u32 too, as drivers
handle NEW/REPLACE in one switch-case - will patch this).

Thanks!

Jiri
