Bill Paul 20ea6dd580 In the device attach routine, don't depend on uaa->iface being
populated. Apparently, if you use an ehci controller, it's not.
Use usbd_device2interface_handle() to retrieve the interface handle.
NOTE: uaa->iface is populated in the probe routine, so I suspect the
fact that it's NULL in the attach routine is a bug in the ehci driver.

Also, don't depend on the PHY addresses returned by the AXE_CMD_READ_PHYID
command. The address is correct for my LinkSys NIC, but a user has
reported that with a D-Link NIC, the PHYID command returns address 4
while the attached Broadcom PHY is in fact strapped for address 0.
Instead, latch onto the first PHY address that returns valid data
during a readreg operation.

* Vendor specific commands
* ASIX conveniently doesn't document the 'set NODEID' command in their
* datasheet (thanks a lot guys).
* To make handling these commands easier, I added some extra data
* which is decided by the axe_cmd() routine. Commands are encoded
* in 16 bites, with the format: LDCC. L and D are both nibbles in
* the high byte. L represents the data length (0 to 15) and D
* represents the direction (0 for vendor read, 1 for vendor write).
* CC is the command byte, as specified in the manual.
