+.SH PPPOE OPTIONS
+To establish PPP link over Ethernet (PPPoE) it is needed to load pppd's
+\fBplugin pppoe.so\fR and then specify option \fBnic-\fIinterface\fR
+instead of modem options \fIttyname\fR and \fIspeed\fR.
+Recognized pppd's PPPoE options are:
+.TP
+.B nic-\fIinterface
+Use the ethernet device \fIinterface\fR to communicate with the peer.
+For example, establishing PPPoE link on \fIeth0\fR interface is done
+by specifying ppp'd option \fBnic-eth0\fR. Prefix \fBnic-\fR for this
+option may be avoided if interface name is unambiguous and does not
+look like any other pppd's option.

+.B pppoe-service \fIname
+Connect to specified PPPoE service name. For backward compatibility also
+\fBrp_pppoe_service\fP option name is supported.

+compatibility also \fBrp_pppoe_ac\fP option name is supported.

+.TP
+.B pppoe-host-uniq \fIstring
+Set the PPPoE Host-Uniq tag to the supplied hex string.
