I suspected the problem was in libnm-glib/nm-
device.c::nm_device_update_description() where it walks up the udev
chain trying to find the vendor and device ID.
The devices are:
$ lspci -nn | grep Ethernet
02:00.0 Ethernet controller [0200]: Intel Corporation 82573L Gigabit Ethernet
Controller [8086:109a]
0a:08.0 Ethernet controller [0200]: Intel Corporation PRO/100 VE Network
Connection [8086:1092] (rev 02)
I then investigated the udev database and discovered that it appears to
be incorrect:
ls -al /dev/.udev/db/net*
-rw-r--r-- 1 root root 155 2010-04-02 02:53 /dev/.udev/db/net:eth0
-rw-r--r-- 1 root root 173 2010-04-02 02:53 /dev/.udev/db/net:wlan0
cat /dev/.udev/db/net:eth0
E:ID_VENDOR_FROM_DATABASE=Intel Corporation
E:ID_MODEL_FROM_DATABASE=PRO/100 VE Network Connection
E:ID_BUS=pci
E:ID_VENDOR_ID=0x8086
E:ID_MODEL_ID=0x1092
There is no entry for eth1, and the entry for eth0 is the "Pro/100 VE"
as reported by nmapplet.
Looking at the udev log I see the interface renaming operations:
KERNEL[1270173183.421930] add

Notice at this point eth1 is 02:00.0 (82573L Gigabit) and eth1 is
0a:08.0 ( PRO/100 VE).

At this point the Pro/100 VE is eth1 and the 82573L Gigabit is
eth1_rename.

Now the 82573L Gigabit is eth0.

Not too sure what those too events were up to.
After the shuffling it looks like udev got itself confused; certainly
the udev database doesn't reflect the state of the system. I'm assuming
it should but I think we need additional input on this from Scott.
