machine but leave your KLSI adapter plugged into your USB port, it
may stay powered on and retain its firmware in memory. Trying to load
the firmware again in this case will wedge the chip. Try to detect this
in the kue_load_fw() routine and bail if the firmware is already
loaded and running.
Also, in the probe/match routine, force the revision code to the
hardware default and force a rescan of the quirk database. This is
necessary because the adapter will return a different revision code
if the firmware has been loaded. Without the firmware, the revision
code is 0x002. With the firmware, the revision code is 0x202. This
confuses the quirk mechanism, which won't match a quirk to a device
unless the revision code agrees with the quirk table entry.
This makes probe/attach of these devices somewhat more reliable.
Also add a few comments about the device's operation.
Kawasaki LSI KL5KUSB101B chip, including the LinkSys USB10T, the
Entrega NET-USB-E45, the Peracom USB Ethernet Adapter, the 3Com
3c19250 and the ADS Technologies USB-10BT. This device is 10mbs
half-duplex only, so there's miibus or ifmedia support. This device
also requires firmware to be loaded into it, however KLSI allows
redistribution of the firmware images (I specifically asked about
this; they said it was ok).
Special thanks to Annelise Anderson for getting me in touch with
KLSI (eventually) and thanks to KLSI for providing the necessary
programming info.
Highlights:
- Add driver files to /sys/dev/usb
- update usbdevs and regenerate attendate files
- update usb_quirks.c
- Update HARDWARE.TXT and RELNOTES.TXT for i386 and alpha
- Update LINT, GENERIC and others for i386, alpha and pc98
- Add man page
- Add module
- Update sysinstall and userconfig.c
