Chapter 5. Interfaces: SLIP and Loopback
In Chapter 4 we looked at the Ethernet interface. In this chapter we describe the SLIP and loopback interfaces, as well as the
ioctl commands used to configure all network interfaces. The TCP compression algorithm used by the SLIP driver is described in Section 29.13. The loopback driver is straightforward and we discuss it here in its entirety.
