Hi,
if I got the point, you are rewriting IPv6 addresses in the IPv6 header, 
by using set_field actions in the rules. I had the same problem in the 
past and what I understood after investigating that problem is that OVS 
does not properly compute the IPv6 checksum due to IP addresses rewrite 
operations. I suppose it is an OVS misbehavior (or bug), completely 
unrelated to the Ryu framework, since it correctly installs rules and 
those rules properly act on the packets.

My feeling is that Ryu framework is not involved in such a problem.
