| 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. |
