└─>"DSCP" and "TOS" target support
In linux kernel since version 2.6.19 (release Date: 2006-11-29)  
This option adds a `DSCP' target, which allows you to manipulate
the IPv4/IPv6 header DSCP field (differentiated services codepoint).

The DSCP field can have any value between 0x0 and 0x3f inclusive.

It also adds the "TOS" target, which allows you to create rules in
the "mangle" table which alter the Type Of Service field of an IPv4
or the Priority field of an IPv6 packet, prior to routing.

To compile it as a module, choose M here. If unsure, say N.
