    fou: fix IPv6 Kconfig options · 95e4daa8
    Arnd Bergmann authored
    The Kconfig options I added to work around broken compilation ended
    up screwing up things more, as I used the wrong symbol to control
    compilation of the file, resulting in IPv6 fou support to never be built
    into the kernel.
    
    Changing CONFIG_NET_FOU_IPV6_TUNNELS to CONFIG_IPV6_FOU fixes that
    problem, I had renamed the symbol in one location but not the other,
    and as the file is never being used by other kernel code, this did not
    lead to a build failure that I would have caught.
    
    After that fix, another issue with the same patch becomes obvious, as we
    'select INET6_TUNNEL', which is related to IPV6_TUNNEL, but not the same,
    and this can still cause the original build failure when IPV6_TUNNEL is
    not built-in but IPV6_FOU is. The fix is equally trivial, we just need
    to select the right symbol.
    
    I have successfully build 350 randconfig kernels with this patch
    and verified that the driver is now being built.
