>Description:
Connecting a Buffalo WLI-U2-KG54L USB WLAN dongle to a
NetBSD-current/i386 machine, it successfully attaches as "zyd0",
but attempting to ifconfig the interface consistently leads
to a kernel trap. Even the command "ifconfig zyd0" (with no
further arguments) causes a crash.
Screenshot of trap message and backtrace:

The screenshot is from a -current as of a couple of weeks ago,
but I have also reproduced the problem with a -current built
from 2010.04.04.23.38.55 sources.

FUKAUMI Naoki suggested on tech-kern@ to introduce aftermountroothook()
to handle deferred initialization that should be done after mountroot():
http://mail-index.NetBSD.org/tech-kern/2010/05/27/msg008261.html
But as I wrote in the thread, I think it's rather better to handle
such device initializations in the autoconf(9) layer as we do
in config_interrupt(9) than adding a common hook because
such MI hooks seem deprecated like shutdownhook_establish(9) etc.
How about this patch that introduces config_mountroot(9)?
(zyd diff is based on FUKAUMI-san's one)

upgt(4) (which requires firmware to get MAC address) on hpcarm
works fine with this patch.

zyd loads the firmware when the interface is put in UP state, but
you may call ioctl on the interface before this. The ioctl may end
in net80211 code that relies on initialized hardware.
So my patch just initializes the hardware on the first ioctl too.
Unfortunately this doesn't make zyd work on my network, there
seem to be other issues as I also see USB errors.
My assumption was that the deferred initialization was to avoid
consuming firmware ressources until the device is actually used
and not about availability of the firmware. It also lets you
load and unload the firmware by just putting the interface up
and down.
Moving initialization into a config_mountroot() looks interesting,
but it looks a bit like it may only happen once and leaves out
the possibility to reload the firmware. Or can you control this
with drvctl?
If drvctl lets you detach and rescan USB devices, then maybe
a solution would be to not even attach the devices before the
firmware is available but to defer all this to an rc script?
Greetings,

Hmm, probably we should ask a person who implemented it,
but my assumption is that it was just a hack since
we didn't have proper hooks to defer initialization
after mountroot(9).

IMO we should have firmware in root file system as kernel modules
and we don't have to defer it to an rc script.
Anyway, your suggestion looks beyond the scope of this PR.

I finally got around to trying it, using NetBSD-current as of source
date 2010.08.01.12.42.45 and a GENERIC kernel. When I connect the
device, I now get the following kernel messages:
zyd0: Buffalo USB2.0 WLAN, rev 2.00/48.10, addr 2
zyd0: sorry, radio "PV2000" is not supported yet
zyd0: could not attach RF
and ifconfig now fails with "Device not configured" rather than a
kernel panic.

One more thing... When I unplug the Buffalo WLI-U2-KG54L after it has
failed to attach with the message "zyd0: could not attach RF",
the kernel panics with "fatal page fault in supervisor mode".
The last line of output before the ddb prompt is:

I just tried a kernel built from today's -current
(2011.02.02.05.10.55), and I was now able to successfully configure
the WLI-U2-KG54L with a WEP key, obtain an address with DHCP, and
transfer some data using ssh. Many thanks to tsutsui for the fix.

Regrettably, I have to retract my report of the Buffalo WLI-U2-KG54L
working. I have two almost identical-looking WLAN sticks, one older
WLI-U2-KG54 (without the -L suffix) and the newer Buffalo WLI-U2-KG54L,
and I accidentally tested the wrong one. So, the WLI-U2-KG54
works, but the WLI-U2-KG54L still doesn't.
The current symptoms (with the 2011.02.02.05.10.55 kernel) are that
setting a WEP key with ifconfig works, but when I run dhclient,
the console starts logging the following message several times a
second:
zyd0: xfer too short (length = 8)
An "ifconfig zyd0 down" stops the messages, and an "ifconfig zyd0 up"
restarts them.

Similar to the SMC device, it complains about too short
transfers with (length = 22).
