Technical Notes

  • VMWare has created a native Fling driver for ESXi that is compatible with the Sonnet Solo5G (which is based on the Marvell Aquantia AQC111U).  The VMWare Fling driver is called USB Network Native Driver for ESXi.  While this driver is not ready for production environments, it is very useful for home labs and other technology investigations.
