Linux kernel source tree

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_opts() instead.
This patch adds a new "type" parameter for connect_to_fd_opts(), then
opts->type and getsockopt(SO_TYPE) can be replaced by "type" parameter in
it.
In connect_to_fd(), use getsockopt(SO_TYPE) to get "type" value and pass
it to connect_to_fd_opts().
In bpf_tcp_ca.c and cgroup_v1v2.c, "SOCK_STREAM" types are passed to
connect_to_fd_opts(), and in ip_check_defrag.c, different types "SOCK_RAW"
and "SOCK_DGRAM" are passed to it.
With these changes, the strcut member "type" of network_helper_opts can be
dropped now.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
