+This module matches the 8-bit Type of Service field in the IPv4 header (i.e.
+including the "Precedence" bits) or the (also 8-bit) Priority field in the IPv6
+header.
+.TP
+[\fB!\fP] \fB--tos\fR \fIvalue\fR[\fB/\fR\fImask\fR]
+Matches packets with the given TOS mark value. If a mask is specified, it is
+logically ANDed with the TOS mark before the comparison.
+.TP
+[\fB!\fP] \fB--tos\fR \fIsymbol\fR
+You can specify a symbolic name when using the tos match for IPv4. The list of
+recognized TOS names can be obtained by calling iptables with \fB-m tos -h\fR.
+Note that this implies a mask of 0x3F, i.e. all but the ECN bits.
