 .IP \fBtun_id=\fItunnel-id\fR[\fB/\fImask\fR]
 Matches tunnel identifier \fItunnel-id\fR.  Only packets that arrive
 over a tunnel that carries a key (e.g. GRE with the RFC 2890 key
-extension) will have a nonzero tunnel ID.  If \fImask\fR is omitted,
-\fItunnel-id\fR is the exact tunnel ID to match; if \fImask\fR is
-specified, then a 1-bit in \fImask\fR indicates that the corresponding
-bit in \fItunnel-id\fR must match exactly, and a 0-bit wildcards that
-bit.
