NM 0.8.997 - instance size for type `NMDeviceWimax' is smaller than the parent type's `NMDevice' instance size

[Lukasz Kies <kiesiu kiesiu com>]

Hi,

I've recently switched from 0.8.2 version to 0.8.997 version and it
stops working with my ethernet card. It's strange as it looks like
some problem with WiMAX.
Here is what I gets when I run NetworkManager as no-daemon:

Killed

It stops responding on "NetworkManager[5127]: <debug>
[1300661846.259277] [nm-device.c:3778] nm_device_state_changed():
(eth0): device not yet available for transition to DISCONNECTED" and
hangs. I cannot close it sending signal 2 or 15, nm-tool is unable to
connect to service. I could only kill it with signal 9.

Rebuilding NetworkManager without WiMAX support resolves problem, but
I don't understand why it's trying to do anything with WiMAX on wired
netrwork adapter.

Best regards,
Lukasz
