This patch changes bpf_getsockopt(SOL_IPV6) to reuse do_ipv6_getsockopt(). It removes the duplicated code from bpf_getsockopt(SOL_IPV6). This also makes bpf_getsockopt(SOL_IPV6) supporting the same set of optnames as in bpf_setsockopt(SOL_IPV6). In particular, this adds IPV6_AUTOFLOWLABEL support to bpf_getsockopt(SOL_IPV6). ipv6 could be compiled as a module. Like how other code solved it with stubs in ipv6_stubs.h, this patch adds the do_ipv6_getsockopt to the ipv6_bpf_stub.

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.
