NAME
       tcindex - traffic control index filter

SYNOPSIS
       tc  filter  ...  tcindex  [ hash SIZE ] [ mask MASK ] [ shift SHIFT ] [
               pass_on | fall_through ] [  classid  CLASSID  ]  [  action  AC-
               TION_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 be-
              fore use. If a mask has been set, masking is done before  shift-
              ing.

       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.
