Hi Eddie, Giorgio,

Attached e1000 v5.2.16 with polling support. It turned out not much had to be changed. I've saved the original 5.2.16 files to *.c.orig . 

This driver hasn't been tested extensively, so I recommend to first try it out in a test environment. I've only tested a couple of days with an Intel Pro/1000MT 82545GM controller, and so far havent experienced any problems in polling mode. Let me know if you pick up any problems, any feedback/testing help is welcome. Small plus, driver now supports mii-tool :) 

Below overview of major changes to original 5.2.16 driver:

In e1000_main.c:
Changed e1000_watchdog timer interrupt to skip polling
enabled adapters and for non-polling adapters to call the
new e1000_watchdog_1 timer interrupt (which is basically
the original e1000_watchdog).

Changed main interrupt handler e1000_intr to only process
non-polling adapters. Polling extensions process modified
e1000_clean_tx__irq in polling code.

In e1000_probe added Polling variables initialization.

Regards

Beyers Cronje

Hi Beyers,

This is great news!  We'd love to accept the code, if you're willing.
