IPv6 reserves 20-bit field in IPv6 header for QoS use. Actual
QoS control needs special queueing of traffic, packet tagging, and
some other things. The queueing/tagging things are separately defined
from IPv6 specification itself (IETF diffserv/intserv working groups),
and are not included in NetBSD-current.
You may want to look at ALTQ suite (alternate queueing framework)
ALTQ is now distributed in KAME IPv6 stack kit (NetBSD-current IPv6
code is based on KAME kit), so you can enjoy tight integration of
KAME IPv6 and ALTQ.
