Traffic control index filter(8)(<2/1a>Oct 2T0r1a5f)fic control index filter(8)

     NAME
          tcindex - traffic control index filter

     SYNOPSIS
          tc filter ... tcindex [ SIZE ] [  mask MASK ] [  shift SHIFT
                  ] [  pass_on | fall_through ] [ classid CLASSID ] [
                  action ACTION_SPEC ]

     DESCRIPTION
          This filter allows to match packets based on their tcindex
          field value, i.e. the combination of the DSCP and ECN fields
          as present in IPv4 and IPv6 headers.

     OPTIONS
          action ACTION_SPEC
               Apply an action from the generic actions framework on
               matching packets.

          classid CLASSID
               Push matching packets into the class identified by
               CLASSID.

          hash SIZE
               Hash table size in entries to use. Defaults to 64.

          mask MASK
               An optional bitmask to binary AND to the packet's
               tcindex field before use.

          shift SHIFT
               The number of bits to right-shift a packet's tcindex
               value before use. If a mask has been set, masking is
               done before shifting.

          pass_on
               If this flag is set, failure to find a class for the
               resulting ID will make the filter fail and lead to the
               next filter being consulted.

          fall_through
               This is the opposite of pass_on and the default. The
               filter will classify the packet even if there is no
               class present for the resulting class ID.
