[Click] Intel Pro/1000MT - 82545GM Controller

[Andy Van Maele]

Hello,

last year we have experienced the same problem with the "Dual" version 
of the Intel Pro/1000MT card. When searching for the differences, we 
then found a product change notification (Intel PCN 103728-01 - see 
attachment) on the intel website stating that the only features that 
have been added to the new controller is Wake-on-LAN. And some less 
power consumption for the single interface version of the series. When 
looking on the Intel website, this PCN is no longer avialable so I've 
added it in attachment.

We solved the problem (thx to Brecht Vermeulen) in the same way, by 
simple adding the device ID 1079 and 1179 to the existing driver as you 
did for the device ID 1026, as you can see in the diff below. We then 
added the necessary lines in the driver for the 82546GB controller 
everywhere we found a piece of code for the 82546EB controller, so the 
driver would work for both versions of the cards.

As I've read in another post 
(https://amsterdam.lcs.mit.edu/pipermail/click/2004-October/003292.html) 
that you've adapted version 5.2.16 of the driver to support polling, it 
seems more interesting to further work with the newer version of the driver.

regards,
Andy Van Maele

PS: the diff in case someone wants to adapt his own driver:

I've managed to get it working by adding the necesary device IDs to the e1000_pci_tbl[] table and changing the existing "#define E1000_DEV_ID_82545EM_COPPER 0x100F" in e1000_hw.h to "#define E1000_DEV_ID_82545EM_COPPER 0x1026" to reflect the new device ID. This workaround seems to work alright, but I'm wondering what functionality/performance I'm loosing.
