* RNDIS is NDIS remoted over USB. It's a MSFT variant of CDC ACM ... of
* course ACM was intended for modems, not Ethernet links! USB's standard
* 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).
