Add-ons/drivers/applications

DHCP client

Leon Woestenberg from Axon Digital Design B.V. has written a CS8900a network interface driver and is currently developing a DHCP client for lwIP. They can both be found here. The plan is to eventually integrate Leon's DHCP client in the main lwIP distribution.

IGMPv2 implementation

Steve Reynolds of Citel Technologies Ltd. has donated his IGMPv2 implementation for lwIP to the community. It is avaliable for download here (note that the copyright and license differs slightly from lwIP - read the license in the igmp.c file). The plan is to integrate his code into the main lwIP distribution.

Alternative BSD socket layer

Paul Sheer has incorporated lwIP into his PaulOS system and has written an alternative BSD socket layer. It is avaliable for download here. It is copyright Paul Sheer and licensed under the GNU GPL.
