Ethernet driver for STM32 CL

Hello Ilija,

Thank you. I've just copied it into cdf file. I hope it's ok and it was your
intention to use your code.

To test ethernet driver I used a simple HTTP server from test module of lwIP
stack and several concurrent ping command with different payload sizes and
intervals

>         - lwIP HW checksum disabled (should use lwIP checksum)
and in both cases eCos works stable and fine.

Due to small amount of RAM >64k and no memory bus to connect external memory I
skipped RedBoot.

Exactly. 

Best regards,
jerzy
