In different changes of my /S/L/E I got different rezults about my Marvell 8040

And sometimes

    | |   |     |   "IOPCIExpressASPMDefault" = 3
    | |   |     | }
    | |   |     | 

In both cases adapter works fine.

Rather old post but I just saw it.
That device ID is just an hardcoded string telling the model name, which is not necessarily the right one but just what the driver "believes". So maybe each kext detects it as a different subversion with minor changes of the device, both working the same way.

The kext is the same in both cases. I found that when LAN is connected then DeviceID=435a, if not connected then DeviceID=4354. It is strange but not terrible.
