Hi all,

After merging the netfilter-next tree, today's linux-next build
(arm imx_v4_v5_defconfig and several others) failed like this:

In file included from net/netfilter/core.c:19:0:
include/linux/netfilter_ipv6.h: In function 'nf_ipv6_cookie_init_sequence':
include/linux/netfilter_ipv6.h:174:2: error: implicit declaration of function '__cookie_v6_init_sequence' [-Werror=implicit-function-declaration]
include/linux/netfilter_ipv6.h: In function 'nf_cookie_v6_check':
include/linux/netfilter_ipv6.h:189:2: error: implicit declaration of function '__cookie_v6_check' [-Werror=implicit-function-declaration]

Caused by commit

  3006a5224f15 ("netfilter: synproxy: remove module dependency on IPv6 SYNPROXY")

This has been happening for a few days, sorry.

# CONFIG_IPV6 is not set
