+\fB\-\-set\-tos\fP \fIvalue\fP[\fB/\fP\fImask\fP]
Zeroes out the bits given by \fImask\fR and XORs \fIvalue\fR into the
TOS/Priority field. If \fImask\fR is omitted, 0xFF is assumed.

-\fB--set-tos\fR \fIsymbol\fR
+\fB\-\-set\-tos\fP \fIsymbol\fP
You can specify a symbolic name when using the TOS target for IPv4. It implies
a mask of 0xFF. The list of recognized TOS names can be obtained by calling
-iptables with \fB-j TOS -h\fR.
