kernel test robot reported the warning below:
>> net/core/filter.c:11842:13: warning: declaration of 'struct bpf_tcp_req_attrs' will not be visible outside of this function [-Wvisibility]
11842 | struct bpf_tcp_req_attrs *attrs, int attrs__sz)
| ^
1 warning generated.
struct bpf_tcp_req_attrs is defined under CONFIG_SYN_COOKIES
but used in kfunc without the config.
Let's move struct bpf_tcp_req_attrs definition outside of
CONFIG_SYN_COOKIES guard.
Fixes: e472f88891ab ("bpf: tcp: Support arbitrary SYN Cookie.")

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 Restructured Text 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.
