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?
If I try to access it within ovpn I get the usual error:
ERROR: modpost: "inet6_stream_ops" [drivers/net/ovpn/ovpn.ko] undefined!
but mptcp compiles just fine.
Any hint?
