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.
