This looks like an hack to avoid a build dependency on IPV6, I think the explicit
I happily copied this approach from espintcp.c:espintcp_init_sk() :-D
#if IS_ENABLED(CONFIG_IPV6)
at init time should be preferable
To get this done at init time I need inet6_stream_ops to be accessible, but it seems there is no EXPORT_SYMBOL() for this object.
However, I see that mptcp/protocol.c is happily accessing it. Any clue how this is possible?
I answer myself: mptcp is not tristate and it can only be compiled as built-in.
Indeed, that's why.
Talking about MPTCP, by chance, do you plan to support it later on? :)
Cheers, Matt
