[lwip-devel] Please comment on suggested development of the cs8900 driver

[Mike Kleshov]

As the new maintainer of the cs8900 driver, I would like to suggest a course of 
action.
First, a little background info would be appropriate. I am currently in the 
process of adding an ethernet interface to an embedded system. The system is 
built around an ARM-based microcontroller with the CS8900A chip attached to it 
via external memory interface. There is no OS, I am planning to use raw API. It 
is planned that the system will run a TELNET-like server to implement a simple 
remote control protocol ('command message'->'response message'.) It will also 
run a simple HTTP server featuring GET, POST and HTTP digest authentication. I 
am using the IAR EWARM software for development.
My suggestion is to create an 'arm_nosys' port containing the cs8900 driver. 
I'll try to avoid using any compiler-specific contructs (except packed 
structure modifier), so the port should be fairly compiler-independent. Also I 
would like to do a rewrite of the driver using lwip/src/netif/ethernetif.c as a 
template and reusing the old driver as much as possible. Hopefully, this would 
bring the driver in line with the latest developments in lwip in terms of API 
and coding/commenting style. Naturally, I'll test the code on my target board 
before submitting.
As soon as I'm satisfied with the quality of my raw API-based HTTP server, I'd 
like to contribute it as well.
All of this will probably take a few weeks.

Does it sound reasonable? All comments are welcome.
