I think it works already with the plain hex/decimal values given,
though we're missing OpenBSD's parser support for special DSCP
options with its funky naming:

"This rule applies to packets with the specified TOS bits set. string
may be one of critical, inetcontrol, lowdelay, netcontrol,throughput,
reliability, or one of the DiffServ Code Points: ef, af11 ... af43,
cs0 ... cs7; number may be either a hex or decimal number."

Looks like pfctl(8) is the only thing to "fix" here.  I'll take a look.


Cheers,
