I hope someone will commit it. DSCP/TOS feature in ipfw is pretty useful
if you're doing VOIP or QoS in generell.

The days where ISPs don't do QoS because they do erything with
"over-provesioning" are over. Most do MPLS QoS but thats more for the
backbone.

I would like to see this patch in the main tree. Of course the DF
modification would be nice too.

Cheers,
Thomas
