Following steps are taken in the driver to offload an XDP program:
XDP_SETUP_PROG:
* prepare:
- allocate program state;
- run verifier (bpf_analyzer());
- run translation;
* load:
- stop old program if needed;
- load program;
- enable BPF if not enabled;
* clean up:
- free program image.
With new infrastructure the flow will look like this:
BPF_OFFLOAD_VERIFIER_PREP:
- allocate program state;
BPF_OFFLOAD_TRANSLATE:
- run translation;
XDP_SETUP_PROG:
- stop old program if needed;
- load program;
- enable BPF if not enabled;
BPF_OFFLOAD_DESTROY:
- free program image.
Take advantage of the new infrastructure. Allocation of driver
metadata has to be moved from jit.c to offload.c since it's now
done at a different stage. Since there is no separate driver
private data for verification step, move temporary nfp_meta
pointer into nfp_prog. We will now use user space context
offsets.
