This patchset adds more bpf_*_ct_lookup() selftests. The goal is to test interaction with netfilter subsystem as well as reading from `struct nf_conn`. The first is important when migrating legacy systems towards bpf. The latter is important in general to take full advantage of connection tracking. I'll follow this patchset up with support for writing to `struct nf_conn`.
