bpf: Test BPF_PROG_TYPE_SK_REUSEPORT
This patch add tests for the new BPF_PROG_TYPE_SK_REUSEPORT.
The tests cover:
- IPv4/IPv6 + TCP/UDP
- TCP syncookie
- TCP fastopen
- Cases when the bpf_sk_select_reuseport() returning errors
- Cases when the bpf prog returns SK_DROP
- Values from sk_reuseport_md
- outer_map => reuseport_array
The test depends on
commit 3eee1f75f2b9 ("bpf: fix bpf_skb_load_bytes_relative pkt length check")
