802.1p tag, VLAN/802.1p tag - Interesting....
Unfortunately I do not think that ip/ebtables are capable of doing that.
However, if someone knows a way to trigger those fields of the ethernet frame

As it concerns the DSCP field of the IP packet - iptables can do the job.

DSCP target options
  --set-dscp value        Set DSCP field in packet header to value
                          This value can be in decimal (ex: 32)
                       or in hex (ex: 0x20)
  --set-dscp-class class    Set the DSCP field in packet header to the
                value represented by the DiffServ class value.
                This class may be EF,BE or any of the CSxx
                or AFxx classes.

                These two options are mutually exclusive !

dscp match options
[!] --dscp value        Match DSCP codepoint with numerical value
                          This value can be in decimal (ex: 32)
                       or in hex (ex: 0x20)
[!] --dscp-class name        Match the DiffServ class. This value may
                be any of the BE,EF, AFxx or CSx classes

                These two options are mutually exclusive !

Looks like a spam preparation post - wouldn't surprise me if a signature link occurs within the next 24 hours.

The discussion might have continued from here.
