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
