[Click] e1000-5.7.6 polling driver

[Beyers Cronje]

Hi,

I've got a working click polling driver based on Intel's latest e1000
v5.7.6 driver. Anyone interested in testing/using the driver pop me an
email.

Stability seems good. Current interface stats runnin in polling mode: 
RX packets:519393113 errors:25 dropped:0 overruns:0 frame:25
TX shows 0 errors.

(Not sure where the 25 frame errors are from, but minute in comparison
with RX packets)

I havent done much performance testing, but should theoretically have
similar performance to the click supplied polling driver.

Tested on Linux 2.4.26 with 82541GI and 82545GM controllers (both
controllers not supported on the supplied click driver).

The driver should provide polling support for the following controllers:
