matching (and handling) a whole device and those which match an interface only. This will allow to enforce some rules, eg that the former don't use interface information for matching or that the latter don't modify global device state. The previous way left too much freedom do the drivers which led to inconsistencies and abuse. For now, I've not changed locators and submatch rules, this will happen later. There should not be any change in behaviour, except in the case of some drivers which did behave inconsistently: if_atu, if_axe, uep: matched the configured device in the interface stage, but did configuration again. I've converted them to match in the device stage. ustir, utoppy: matched in the interface stage, but only against vendor/device information, and used any configuration/interface without checking. Changed to match in device stage, and added some simple code to configure and use the first interface. If you have one of those devices, please test!

* The Pegasus chip uses four USB "endpoints" to provide 10/100 ethernet
|
|
* support: the control endpoint for reading/writing registers, burst
|
|
* read endpoint for packet reception, burst write for packet transmission
|
|
* and one for "interrupts." The chip uses the same RX filter scheme
|
|
* as the other ADMtek ethernet parts: one perfect filter entry for the
|
|
* the station address and a 64-bit multicast hash table. The chip supports
|
|
* both MII and HomePNA attachments.
|
|
*
|
|
* Since the maximum data transfer speed of USB is supposed to be 12Mbps,
|
|
* you're never really going to get 100Mbps speeds from this device. I
|
|
* think the idea is to allow the device to connect to 10 or 100Mbps
|
|
* networks, not necessarily to provide 100Mbps performance. Also, since
|
|
* the controller uses an external PHY chip, it's possible that board
|
|
* designers might simply choose a 10Mbps PHY.
|
|
*
|
|
* Registers are accessed using usbd_do_request(). Packet transfers are
|
|
* done using usbd_transfer() and friends.
