udp: advertise ipv6 udp support for msghdr::ubuf_info
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(), but d38afeec26ed4 ("tcp/udp: Call inet6_destroy_sock() in IPv6 ...") removed it and so ipv6 udp misses the flag. Cc: <stable@vger.kernel.org> # 6.0 Fixes: e993ffe3da4bc ("net: flag sockets supporting msghdr originated zerocopy") Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
