+.SH DESCRIPTION
|
|
|
049c96 |
+This filter allows to match packets based on their
|
|
|
049c96 |
+.B tcindex
|
|
|
049c96 |
+field value, i.e. the combination of the DSCP and ECN fields as present in IPv4
|
|
|
049c96 |
+and IPv6 headers.
|
|
|
049c96 |
+.SH OPTIONS
|
|
|
049c96 |
+.TP
|
|
|
049c96 |
+.BI action " ACTION_SPEC"
|
|
|
049c96 |
+Apply an action from the generic actions framework on matching packets.
|
|
|
049c96 |
+.TP
|
|
|
049c96 |
+.BI classid " CLASSID"
|
|
|
049c96 |
+Push matching packets into the class identified by
|
|
|
049c96 |
+.IR CLASSID .
|
|
|
049c96 |
+.TP
|
|
|
049c96 |
+.BI hash " SIZE"
|
|
|
049c96 |
+Hash table size in entries to use. Defaults to 64.
|
|
|
049c96 |
+.TP
|
|
|
049c96 |
+.BI mask " MASK"
|
|
|
049c96 |
+An optional bitmask to binary
|
|
|
049c96 |
+.BR AND " to the packet's " tcindex
|
|
|
049c96 |
+field before use.
|
|
|
049c96 |
+.TP
|
|
|
049c96 |
+.BI shift " SHIFT"
|
|
|
049c96 |
+The number of bits to right-shift a packet's
|
|
|
049c96 |
+.B tcindex
|
|
|
049c96 |
+value before use. If a
|
|
|
049c96 |
+.B mask
|
|
|
049c96 |
+has been set, masking is done before shifting.
|
|
|
049c96 |
+.TP
|
|
|
049c96 |
+.B pass_on
|
|
|
049c96 |
+If this flag is set, failure to find a class for the resulting ID will make the
|
|
|
049c96 |
+filter fail and lead to the next filter being consulted.
|
|
|
049c96 |
+.TP
|
|
|
049c96 |
+.B fall_through
|
|
|
049c96 |
+This is the opposite of
|
|
|
049c96 |
+.B pass_on
|
|
|
049c96 |
+and the default. The filter will classify the packet even if there is no class
|
|
|
049c96 |
+present for the resulting class ID.
