RE: [lwip-users] How to use Lwip with ethernet in Linux

[Taranowski, Thomas \(SWCOE\)]

There are only a few points in which you have to integrate, all of which
are covered in the ethernetif.c code template.

Basically,
1.) Implement a link_output(), which sends a chunk of data to the driver
to be sent.  
2.) Add in a call to ip_input() in your receive ISR, or hardware polling
process.

There are also a number of other additional points that need to be taken
care of, but I believe the code template pretty much takes care of
those.
