Ian Dowse eadf519a78 Replace the static "qdat" structure with a per-instance softc field
in all USB ethernet drivers. The qdat structure contains a pointer
to the interface's struct ifnet and is used to process incoming
packets, so simultaneous use of two similar devices caused crashes
and confusion.

The if_udav driver appeared in the tree since Daan's PR, so I made
similar changes to that driver too.

* Register definitions for ADMtek Pegasus AN986 USB to Ethernet
* chip. The Pegasus uses a total of four USB endpoints: the control
* endpoint (0), a bulk read endpoint for receiving packets (1),
* a bulk write endpoint for sending packets (2) and an interrupt
* endpoint for passing RX and TX status (3). Endpoint 0 is used
* to read and write the ethernet module's registers. All registers
* are 8 bits wide.
*
* Packet transfer is done in 64 byte chunks. The last chunk in a
* transfer is denoted by having a length less that 64 bytes. For
* the RX case, the data includes an optional RX status word.

* Note that while the ADMtek technically has four
* endpoints, the control endpoint (endpoint 0) is
* regarded as special by the USB code and drivers
* don't have direct access to it. (We access it
* using usbd_do_request() when reading/writing
* registers.) Consequently, our endpoint indexes
* don't match those in the ADMtek Pegasus manual:
* we consider the RX data endpoint to be index 0
* and work up from there.
