Roland:

Thanks for the patch. Based on some feedback from the community we had
developed a patch several weeks ago. We just submitted the patch. Please
let me know if you see any issues with it.

Thanks,
Ganesh.

Subject: [PATCH][resend] Update e1000 to use module_param()

(resending because this seems to have been lost; e1000 still has mixed
MODULE_PARM and module_param use)

The change to e1000_main.c in

    ChangeSet@xxxxxxxxxxx, 2004-05-27 13:44:06-04:00,
ganesh.venkatesan@xxxxxxxxx
      [PATCH] e1000 7/7: Support for ethtool msglevel based error

added module_param(debug, ...) to e1000_main.c.  Since e1000_param.c
still uses MODULE_PARM(), this means that one gets

    e1000: Ignoring new-style parameters in presence of obsolete ones

when e1000 is loaded, so the debug parameter cannot even be set.

The patch below fixes this by updating e1000_param.c to use
module_param() as well.  Since module_param might make the parameters
visible in sysfs, I removed the __devinitdata notation from the
parameter arrays as well, just to be safe.

Thanks,
  Roland
