rndis_host: support Hytera digital radios
commit 29262e1f773b4b6a43711120be564c57fca07cfb upstream. Hytera makes a range of digital (DMR) radios. These radios can be programmed to a allow a computer to control them over Ethernet over USB, either using NCM or RNDIS. This commit adds support for RNDIS for Hytera radios. I tested with a Hytera PD785 and a Hytera MD785G. When these radios are programmed to set up a Radio to PC Network using RNDIS, an USB interface will be added with class 2 (Communications), subclass 2 (Abstract Modem Control) and an interface protocol of 255 ("vendor specific" - lsusb even hints "MSFT RNDIS?"). This patch is similar to the solution of this StackOverflow user, but that only works for the Hytera MD785: https://stackoverflow.com/a/53550858 To use the "Radio to PC Network" functionality of Hytera DMR radios, the radios need to be programmed correctly in CPS (Hytera's Customer Programming Software). "Forward to PC" should be checked in "Network" (under "General Setting" in "Conventional") and the "USB Network Communication Protocol" should be set to RNDIS.
