Rx jumbograms have nothing to do with IPv6. OpenAFS has no IPv6 support at present. See "-jumbo" option on the UNIX CM and servers and the equivalent registry value for Windows that is documented in Appendix A of the OpenAFS for Windows Release Notes. >> [...] >> On Windows, there is one type of cache.
