| .SH DESCRIPTION |
| This filter allows 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. |
