NAME # ppp - Point-to-Point Protocol network interface
SYNOPSIS # pseudo-device ppp
DESCRIPTION # The ppp interface allows serial lines to be used as network interfaces using the Point-to-Point Protocol (PPP).
A ppp interface can be created at runtime using the ifconfig ppp‌N create command or by setting up a hostname.if(5) configuration file for netstart(8).

NAME # pppoe - PPP Over Ethernet protocol network interface
SYNOPSIS # pseudo-device pppoe
DESCRIPTION # The pppoe interface encapsulates Point-to-Point Protocol (PPP) packets inside Ethernet frames as defined by RFC 2516.
This is often used to connect a router via a DSL modem to an access concentrator. The pppoe interface does not by itself transmit or receive frames, but needs an Ethernet interface to do so.

NAME # sppp - PPP and Link Control Protocol
SYNOPSIS # pseudo-device sppp [count]
DESCRIPTION # The sppp network layer implements the state machine and Link Control Protocol (LCP) of the Point-to-Point Protocol (PPP) as described in RFC 1661. Note that this layer does not provide network interfaces of its own, it is rather intended to be layered on top of drivers providing a point-to-point connection that wish to run a PPP stack over it.
