vmxnet3s MAC callbacks erroneously return DDI_ return values
Device callbacks for the MAC module are expected to return 0 for success, and a positive non-zero error code (errno) on failure. The vmxnet3s driver's MAC callbacks currently only return DDI_SUCCESS or DDI_FAILURE. The fact that DDI_SUCCESS is 0 is a happy and harmless coincidence, but the lack of error codes could be problematic for diagnostic purposes.
