The driver cannot allocate sufficient memory for resources. These messages
occur when attempting to load the driver. You will be unable to load the driver
until sufficient memory becomes free. Terminating unnecessary processes or

condition should be transitory.
The driver could not allocate enough receive buffers for the interface. The
interface will not be usable.
