commit 472caa69183f("netfilter: nat: un-export nf_nat_used_tuple") introduce NF_NAT_MANIP_SRC/DST enum in include/net/netfilter/nf_nat.h, and commit b06b45e82b59("selftests/bpf: add tests for bpf_ct_set_nat_info kfunc") use NF_NAT_MANIP_SRC/DST in test_bpf_nf.c.
In bpf kself-test config (tools/testing/selftests/bpf/config) nf_nat is compiled as built-in, this issue occurs just if it is compiled as module. we just hardcode 1/0 here.
How to reproduce the error:
$ make -C tools/testing/selftests/bpf/ ... CLNG-BPF [test_maps] test_bpf_nf.bpf.o error: use of undeclared identifier 'NF_NAT_MANIP_SRC' bpf_ct_set_nat_info(ct, &saddr, sport, NF_NAT_MANIP_SRC); ^ error: use of undeclared identifier 'NF_NAT_MANIP_DST' bpf_ct_set_nat_info(ct, &daddr, dport, NF_NAT_MANIP_DST); ^ 2 errors generated.

This will fix the compilation, but the selftest won't actually work when nf_nat is compiled as a module (see [0]). Would be better to fix the test properly instead of just papering over the compilation issue like this. That requires a bit more surgery to the selftests, though...
