Currently, if a user wants to run pmtu.sh and cover all the provided test

Until recently, the ovs-dpctl utility was used with a limited actions set

Hi Barry,
Thanks for the wonderful test program.
I have also used other swap test programs as well. A lot of those
tests are harder to setup up and run.
This test is very quick and simple to run. It can test some hard to
hit corner cases for me.
I am able to reproduce the warning and the kernel

v6:
- update ASSERT strings in patch 4 as Eduard suggested. (thanks)
v5:
- update patch 1, add getsockopt(SO_PROTOCOL) in connect_to_fd() to
fix errors reported by CI.
v4:
- fix errors reported by CI.
v3:
- rename start_client to client_socket
- Use connect_to_addr in c

The opts.{type, noconnect} is at least a bit non intuitive or unnecessary.
The only use case now is in test_bpf_ip_check_defrag_ok which ends up
bypassing most (or at least some) of the connect_to_fd_opts() logic. It's
much better that test should have its own connect_to_fd_opt
From: Geliang Tang
This patch moves "post_socket_cb" and "noconnect" into connect_to_addr(),
then connect_to_fd_opts() can be implemented by getsockname() and
connect_to_addr(). This change makes connect_to_* interfaces more unified.

This patch extracts a new helper client_socket() from connect_to_fd_opts()
to create the client socket, but don't connect to the server. Then
connect_to_fd_opts() can be implemented using client_socket() and
connect_fd_to_addr(). This helper can be used in connect_to_addr() too
From: Geliang Tang
In test_bpf_ip_check_defrag_ok(), the new helper client_socket() can be
used to replace connect_to_fd_opts() with "noconnect" opts, and the strcut
member "noconnect" of network_helper_opts can be dropped now, always
connect to server in connect_to_fd_opts().

Since start_server_str() is added now, it can be used in mptcp.c in
start_mptcp_server() instead of using helpers make_sockaddr() and
start_server_addr() to simplify the code.
