ehea: IBM eHEA Ethernet Device Driver

Hi,

this is the latest version of the IBM eHEA Ethernet Device Driver. We got a lot of very helpful comments and modified our driver as we said in our replies.

Thanks for your efforts so far!

Things we are still working on:
- Debug output rework (EDEB, remove unimportant debug information, using standard kernel mechanisms where possible)
- performance improvements on SMP systems
- error recovery

Thanks,
Jan-Bernd
