What platform and software? I'm not sure all platforms supports marking
on egress.

The 802.1p bits are carried in the 802.1Q tag, so you would have to mark
on the physical interface, not the subinterface.

Depending on the platform you might be able to use DSCP marking on the
subinterface and the a CoS-to-DSPC map that acts on the physical
interface.
