(Linux kernels are trying to stick to a release-every-3-months schedule).
RHEL/CentOS 5 is using a 2.6.18 kernel. The needed support for stateful IPv6
landed in 2.6.21 or so (so almost a year after RHEL 5 did its feature freeze).
RHEL 6 is apparently a 2.6.32 kernel so it should be there. Cutting edge kernel
is currently 2.6.38-rc2.
