mptcp: Fix undefined mptcp_handle_ipv6_mapped for modular IPV6
If CONFIG_MPTCP=y, CONFIG_MPTCP_IPV6=n, and CONFIG_IPV6=m: ERROR: "mptcp_handle_ipv6_mapped" [net/ipv6/ipv6.ko] undefined! This does not happen if CONFIG_MPTCP_IPV6=y, as CONFIG_MPTCP_IPV6 selects CONFIG_IPV6, and thus forces CONFIG_IPV6 builtin. As exporting a symbol for an empty function would be a bit wasteful, fix this by providing a dummy version of mptcp_handle_ipv6_mapped() for the CONFIG_MPTCP_IPV6=n case. Rename mptcp_handle_ipv6_mapped() to mptcpv6_handle_mapped(), to make it clear this is a pure-IPV6 function, just like mptcpv6_init(). Fixes: cec37a6e41aae7bf ("mptcp: Handle MP_CAPABLE options for outgoing connections") Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: David S. Miller <davem@davemloft.net>
