SKELETONS = rss.bpf.skeleton.h
ebpf: Added eBPF RSS program. RSS program and Makefile to build it. The bpftool used to generate '.h' file. The data in that file may be loaded by libbpf. EBPF compilation is not required for building qemu. You can use Makefile if you need to regenerate rss.bpf.skeleton.h.

ebpf: fix compatibility with libbpf 1.0+ The current implementation fails to load on a system with libbpf 1.0 and reports that legacy map definitions in 'maps' section are not supported by libbpf v1.0+. This commit updates the Makefile to add BTF (-g flag) and appropriately updates the maps in rss.bpf.c and update the skeleton file in repo.
