 Log Message:
 urndis(4): Match more interface ids.
 
 There are some others we should consider too, based on what OpenBSD,
 FreeBSD, and Linux match, but I haven't tested with these devices:
 
    class           subclass                        protocol
 1. 0x02 (CDC)      0x02 (abstract control model)   0xff (? rndis?)
 2. 0xef (misc)     0x01 (sync)                     0x01 (active)
 3. 0xef (misc)     0x04 (rndis)                    0x03 (wimax)
 4. 0xef (misc)     0x04 (rndis)                    0x04 (wwan)
 
 Note: FreeBSD uses `UIPROTO_RNDIS' for (3) even though the USB-IF
 registry lists class 0xef, subclass 0x04, protocol 0x04 as `RNDIS
 over WiMAX'; likewise `UIPROTO_ACTIVESYNC' for (4) even though it's
 listed as `RNDIS over WWAN'.  My guess is that for class 0xef
 subclass 0x04, _any_ protocol will really be RNDIS, and it was a
 mistake for FreeBSD to use those protocol numbers (which context
 suggests were supposed to apply to different subclasses).
