[etherlab-dev] Module ec_e1000 for kernel version 2.6.22 (not working)

[Erwin Burgstaller]

Hi, 

I've got two Intel Gigabit Controller:

«Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05)»

and I'd like to run them. In best case as a pair, the second as backup
device, just for to see how that works.

I've tried to port the source from 2.6.20 to 2.6.22. Again I extracted a
patch from the 2.6.20 orig- and ethercat files and applied them to the
2.6.22-code. Except for e1000_main-2.6.22-ethercat.c, there was not much
to do.

It compiles fine and loads:

# lsmod

uhci_hcd               29592  0 


But it does not put out any datagrams to the ring:

Does anybody have a working Module for kernel 2.6.22?

I've attached my port to that posting.

Almost forgot: If I switch the cable to the rtl-8139 card and have the
changes in /etc/sysconfig/ethercat done, it works. 


Another thing: When I leave both devices configured:

DEVICE_MODULES="e1000 8139too"

apart from not working, stopping ethercat results in flashing caps- and
num-lock on the keyboard, and as usual with that signs, a frozen machine.

Best regards,
Erwin
