Looks like CI failed here:
[...] progs/test_bpf_nf.c:178:11: error: no member named 'mark' in 'struct nf_conn' if (ct->mark == 42) ~~ ^ 1 error generated. make: *** [Makefile:521: /tmp/runner/work/bpf/bpf/tools/testing/selftests/bpf/test_bpf_nf.o] Error 1 make: *** Waiting for unfinished jobs.... Error: Process completed with exit code 2.
Likely due to missing CONFIG_NF_CONNTRACK_MARK for the CI instance.
