IIUC, MODULE_FIRMWARE is only necessary for devices that need firmware
to operate.  vxge hardware has an image in flash on the nic, and the
modified code is used to update the firmware image on the adapter.
So, this change isn't doing what you want it to do.

Also, wasn't this already discussed (https://lkml.org/lkml/2012/4/12/401)?

Thanks,
Jon
