Statistics

The dscpmk module exports the following statistics available through kstat:

Global statistics:

module: dscpmk                     instance: <action id>
  name: dscpmk stats               class <action name>
        crtime
        snaptime
        npackets                    <number of packets>
        epackets                    <number of packets in error>
        ipackets                    <number of packets not processed>
        dscp_unchanged              <number of packets with DSCP unchanged>
        dscp_changed                <number of packets with DSCP changed>

Also, for each DSCP the following is exported:
     module: dscpmk                         instance: <action id>        
     name: dscpmk_dscp0x<DSCP> value class:  <action name>
     dscp                                   <DSCP value>
