These size requirements may be a challenge. I wish you luck.

I guess you're talking about these functions:
ovs_be32 stream_get_remote_ip(const struct stream *);
ovs_be16 stream_get_remote_port(const struct stream *);
ovs_be32 stream_get_local_ip(const struct stream *);
ovs_be16 stream_get_local_port(const struct stream *);
Those are only important for implementing in-band control. There
would be no need to tie adding support for IPv6 controllers to adding
*in-band* support for IPv6 controllers. You could ignore them and
just return 0.
