-.SH NAME
-tcindex \- traffic control index filter
-.SH SYNOPSIS
-.in +8
-.ti -8
-.BR tc " " filter " ... " tcindex " [ " hash
-.IR SIZE " ] [ "
-.B mask
-.IR MASK " ] [ "
-.B shift
-.IR SHIFT " ] [ "
-.BR pass_on " | " fall_through " ] [ " classid
-.IR CLASSID " ] [ "
-.B action
-.BR ACTION_SPEC " ]"
-.SH DESCRIPTION
-This filter allows one to match packets based on their
-.B tcindex
-field value, i.e. the combination of the DSCP and ECN fields as present in IPv4
-and IPv6 headers.
-.SH OPTIONS
-.TP
-.BI action " ACTION_SPEC"
-Apply an action from the generic actions framework on matching packets.
-.TP
-.BI classid " CLASSID"
-Push matching packets into the class identified by
-.IR CLASSID .
-.TP
-.BI hash " SIZE"
-Hash table size in entries to use. Defaults to 64.
-.TP
-.BI mask " MASK"
-An optional bitmask to binary
-.BR AND " to the packet's " tcindex
-field before use.
-.TP
-.BI shift " SHIFT"
-The number of bits to right-shift a packet's
-.B tcindex
-value before use. If a
-.B mask
-has been set, masking is done before shifting.
-.TP
-.B 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.
-.TP
-.B fall_through
-This is the opposite of
-.B pass_on
-and the default. The filter will classify the packet even if there is no class
-present for the resulting class ID.
