Netfilter Connection Mark Actions

modulename: act_ctinfo.ko


Linux Kernel Configuration
└─>Networking support
└─>Networking options
└─>QoS and/or fair queueing
└─>Network packet filtering framework (Netfilter)
└─>Netfilter Connection Mark Actions
In linux kernel since version 5.1 (release Date: 2019-05-05)  
Say Y here to allow transfer of a connmark stored information.
Current actions transfer connmark stored DSCP into
ipv4/v6 diffserv and/or to transfer connmark to packet
mark. Both are useful for restoring egress based marks
back onto ingress connections for qdisc priority mapping

If unsure, say N.

To compile this code as a module, choose M here: the
module will be called act_ctinfo.
