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.
