Having done some experiments with the some of the UA¹s, as a developer I
would like to 1) have a feedback on whether the UA supports the setting or
not, and 2) that the UA expose the marking set for debugging up and
downstream.

Œ1¹ would imply UA has/will applied/y the setting of the Œlocal
prioritisation¹ and setting of DSCP upstream packets while Œ2¹ is useful
for the purpose of debugging downstream.

A UA that does not support Œ1¹ (for whatever reason not limited to OS
capabilities) should provide such a feedback.

This was my 5 cent, :-).

Be Well!
