32 * RNDIS is NDIS remoted over USB. It's a MSFT variant of CDC ACM ... of
33 * course ACM was intended for modems, not Ethernet links! USB's standard
34 * for Ethernet links is "CDC Ethernet", which is significantly simpler.
36 * NOTE that Microsoft's "RNDIS 1.0" specification is incomplete. Issues
38 * - Power management in particular relies on information that's scattered
39 * through other documentation, and which is incomplete or incorrect even
41 * - There are various undocumented protocol requirements, such as the
42 * need to send unused garbage in control-OUT messages.
43 * - In some cases, MS-Windows will emit undocumented requests; this
44 * matters more to peripheral implementations than host ones.
46 * Moreover there's a no-open-specs variant of RNDIS called "ActiveSync".
48 * For these reasons and others, ** USE OF RNDIS IS STRONGLY DISCOURAGED ** in
49 * favor of such non-proprietary alternatives as CDC Ethernet or the newer (and
50 * currently rare) "Ethernet Emulation Model" (EEM).
54 * RNDIS notifications from device: command completion; "reverse"
