 I've replicated this issue as well, on 10.0-RELEASE, amd64. With jails
 running on a cloned lo1, outbound IPv6 works fine, but pf redirect
 traffic gets results in incorrect checksums and traffic being dropped.
 Loopback interfaces no longer seem to support the -txcsum6 or -rxcsum6
 flags. Would love to have a fix for this, as it kind of breaks the
 "service jail" model for IPv6.
 
 Cheers,
 David
