IPv6 flow id hash calculation

This question is related to the hash calculation done as part of selecting
the transmit queue for IPv6 traffic.
I observed that no matter how many queues you use in the driver, the tx
traffic is always coming on queue 0.
Did anybody else observed this behaviour? and is that how it is in freebsd?

Note: IPv4 traffic is coming on all the tx queues.

Please clarify.
