  * RNDIS is NDIS remoted over USB.  It's a MSFT variant of CDC ACM ... of

  * for Ethernet links is "CDC Ethernet", which is significantly simpler.
+ *
+ * NOTE that Microsoft's "RNDIS 1.0" specification is incomplete.  Issues
+ * include:
+ *    - Power management in particular relies on information that's scattered
+ *      through other documentation, and which is incomplete or incorrect even
+ *      there.
+ *    - There are various undocumented protocol requirements, such as the
+ *      need to send unused garbage in control-OUT messages.
+ *    - In some cases, MS-Windows will emit undocumented requests; this
+ *      matters more to peripheral implementations than host ones.
+ *
+ * For these reasons and others, ** USE OF RNDIS IS STRONGLY DISCOURAGED ** in
+ * favor of such non-proprietary alternatives as CDC Ethernet or the newer (and
+ * currently rare) "Ethernet Emulation Model" (EEM).
