Subject: forcedeth: fix MAC address detection on network card (regression in 2.6.23)
From: Michael Pyne <michael.pyne@xxxxxxxxxxx>
Partially revert a change to mac address detection introduced to the forcedeth
driver. The change was intended to correct mac address detection for newer
nVidia chipsets where the mac address was stored in reverse order. One of
those chipsets appears to still have the mac address in reverse order (or at
least, it does on my system).
The change that broke mac address detection for my card was commit
ef756b3e56c68a4d76d9d7b9a73fa8f4f739180f "forcedeth: mac address correct"
My network card is an nVidia built-in Ethernet card, output from lspci as
follows (with text and numeric ids):
$ lspci | grep Ethernet
00:07.0 Bridge: nVidia Corporation MCP61 Ethernet (rev a2)
$ lspci -n | grep 07.0
00:07.0 0680: 10de:03ef (rev a2)
The vendor id is, of course, nVidia. The device id corresponds to the
NVIDIA_NVENET_19 entry.
The included patch fixes the MAC address detection on my system.
Interestingly, the MAC address appears to be in the range reserved for my
motherboard manufacturer (Gigabyte) and not nVidia.
