This patch adds a base for MPTCP specific tests.
It is currently limited to the is_mptcp field in case of plain TCP
connection because there is no easy way to get the subflow sk from a msk
in userspace. This implies that we cannot lookup the sk_storage attached
to the subflow sk in the sockops program.
v4:
- add copyright 2022 (Andrii)
- use ASSERT_* instead of CHECK_FAIL (Andrii)
- drop SEC("version") (Andrii)
- use is_mptcp in tcp_sock, instead of bpf_tcp_sock (Martin & Andrii)
v5:
- Drop connect_to_mptcp_fd (Martin)
- Use BPF test skeleton (Andrii)
- Use ASSERT_EQ (Andrii)
- Drop the 'msg' parameter of verify_sk
