This port is built for ecos 3.0, or better said, for CVS head. I'm not 
sure if it would run for ecos 2.0 too.

The easiest way to integrate this with your code base is to just remove 
the old packages/net/lwip_tcpip folder and replace it with the new 
lwip_tcpip folder. The package also needs to be registered in the 
packages/ecos.db file, but nothing has changed here from the old lwip 
port to the new one, so don't have to change that.

Once this is integrated you can just add lwip to your project as with 
the earlier port.

ecosconfig add lwip

Or you can use the configtool to add the package. Configuration has 
changed considerably from the earlier port, but it's much better 
organized now and should be relatively easy to do.

For a few examples of how to use the port see the examples!

There are two supported modes for running lwip. I called them 
"sequential" and "simple" modes. In the simple mode you run lwip in a 
single thread, making it very resource friendly. But you need to use the 
RAW APIs in this mode. In the sequential mode, lwip is run in multiple 
threads and you can use all the advanced APIs like netconn and sockets.

Best regards
