The build header functions are not used by any other code.
net/ipv6/fou6.c:36:5: warning: no previous prototype for ‘fou6_build_header’ [-Wmissing-prototypes]
net/ipv6/fou6.c:54:5: warning: no previous prototype for ‘gue6_build_header’ [-Wmissing-prototypes]Need to do some code rearranging to satisfy different Kconfig possiblities.

A previous patch added the fou6.ko module, but that failed to link
in a couple of configurations:net/built-in.o: In function `ip6_tnl_encap_add_fou_ops':
net/ipv6/fou6.c:88: undefined reference to `ip6_tnl_encap_add_ops'
net/ipv6/fou6.c:94: undefined reference to `ip6_tnl_encap_add_ops'
net/ipv6/fou6.c:97: undefined reference to `ip6_tnl_encap_del_ops'
net/built-in.o: In function `ip6_tnl_encap_del_fou_ops':
net/ipv6/fou6.c:106: undefined reference to `ip6_tnl_encap_del_ops'
net/ipv6/fou6.c:107: undefined reference to `ip6_tnl_encap_del_ops'If CONFIG_IPV6=m, ip6_tnl_encap_add_ops/ip6_tnl_encap_del_ops
are in a module, but fou6.c can still be built-in, and that
obviously fails to link.Also, if CONFIG_IPV6=y, but CONFIG_IPV6_TUNNEL=m or
CONFIG_IPV6_TUNNEL=n, the same problem happens for a different
reason.This adds two new silent Kconfig symbols to work around both
problems:- CONFIG_IPV6_FOU is now always set to 'm' if either CONFIG_NET_FOU=m
or CONFIG_IPV6=m
- CONFIG_IPV6_FOU_TUNNEL is set implicitly when IPV6_FOU is enabled
and NET_FOU_IP_TUNNELS is also turned out, and it will ensure
that CONFIG_IPV6_TUNNEL is also available.The options could be made user-visible as well, to give additional
room for configuration, but it seems easier not to bother users
with more choice here.Signed-off-by: Arnd Bergmann
