NAME
       tcindex - traffic control index filter

SYNOPSIS
       tc  filter  ...	tcindex	 [ hash SIZE ] [ mask MASK ] [ shift SHIFT ] [
	       pas_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.
