This patchset adds support for passing an xdp_md via ctx_in/ctx_out in bpf_attr for BPF_PROG_TEST_RUN of XDP programs. Patch 1 adds initial support for passing XDP meta data in addition to packet data. Patch 2 adds support for also specifying the ingress interface and rx queue. Patch 3 adds selftests to ensure functionality is correct.
