[PATCH bpf-next v4 0/6] use network helpers, part 5

[Geliang Tang <geliang@kernel.org>]

From: Geliang Tang <tanggeliang@kylinos.cn>

This patchset uses post_socket_cb and post_connect_cb callbacks of struct
network_helper_opts to refactor do_test() in bpf_tcp_ca.c to move dctcp
test dedicated code out of do_test() into test_dctcp().

v4:
 - address Martin's comments in v3 (thanks).
 - drop 2 patches, keep "type" as the individual arg to start_server_addr,
   connect_to_addr and start_server_str.

v3:
 - Add 4 new patches, 1-3 are cleanups. 4 adds a new helper.
 - address Martin's comments in v2.

v2:
 - rebased on commit "selftests/bpf: Add test for the use of new args in
 cong_control"
