ToS-like processing of the IPv6 Traffic Class?

[Fernando Gont]

Hi, folks,

I'm told that many deployments of IPv6 use the RFC 791 ToS (Type of
Service) semantics/definitions for the IPv6 Traffic Class field, e.g.
allowing strict precedence queuing.

Can anybody confirm this?

If this is the case, does this thing have to be explicitly enabled, or
is it the "default" behavior in some implementations?

Thanks!

Kind regards,
