This directory contains generic network interface device drivers that
do not contain any hardware or architecture specific code. The files
are:
etharp.c
Implements the ARP (Address Resolution Protocol) over
Ethernet. The code in this file should be used together with
Ethernet device drivers. Note that this module has been
largely made Ethernet independent so you should be able to
adapt this for other link layers (such as Firewire).
ethernetif.c
An example of how an Ethernet device driver could look. This
file can be used as a "skeleton" for developing new Ethernet
network device drivers. It uses the etharp.c ARP code.
loopif.c
A "loopback" network interface driver. It requires configuration
through the define LWIP_LOOPIF_MULTITHREADING (see opt.h).
slipif.c
A generic implementation of the SLIP (Serial Line IP)
protocol. It requires a sio (serial I/O) module to work.
ppp/ Point-to-Point Protocol stack
