Sorry, but I don't understand why this rename is needed.

Are you going to add another type than BPF_PROG_TYPE_XDP?

I'm adding commands which can be used for cls_bpf programs as well:

+	/* BPF program for offload callbacks, invoked at program load time. */
+	BPF_OFFLOAD_VERIFIER_PREP,
+	BPF_OFFLOAD_TRANSLATE,
+	BPF_OFFLOAD_DESTROY,
