I was not sure about adding this to message.c, because of the USB_CDC_GET_NET_ADDRESS. I had found references to SET_ADDRESS in the USB protocol at https://wiki.osdev.org/Universal_Serial_Bus#USB_Protocol. If one wanted a generic USB function for SET_ADDRESS, to be used for both sending a MAC address and receiving one, how would you suggest this be implemented? This is a legit question because I am curious. Your feedback led to moving the functionality into cdc_ncm.c for today's testing, and removing all changes from messages.c, usb.h, usbnet.c, and usbnet.h. This may be where I end up long term, but I would like to learn if there is a possible solution that could live in message.c and be callable from other USB-to-Ethernet aware drivers. Thank you again, Charles Hyde
