Mark udp ipv6 as supporting msghdr::ubuf_info. In the original commit SOCK_SUPPORT_ZC was supposed to be set by a udp_init_sock() call from udp6_init_sock(), butd38afeec26("tcp/udp: Call inet6_destroy_sock() in IPv6 ...") removed it and so ipv6 udp misses the flag.

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.
