I'm not sure which fix is correct though. Should we have software QoS

Or we could change the enable code path. Hmm.

That patch does prevent the oops. I was not able to make a connection with the
device, but I just acquired it, and I'm not sure of its quality, or that of the
driver.

I don't think that device works today -- IIRC it requires the BSSID
before authentication and that wasn't possible before the auth redesign.

It does scan OK, and I think the patch is OK. I'll do more tests with
b43legacy later as the machine with that iface is busy. I will also test b43 on
the PPC using the open-source firmware.

Although you may want to change the enable code path, some patch will be needed
to prevent a regression in 3.5. If this is the one, you may add a "Tested-by"
for me.

Thanks. Could you try this patch instead? I think it makes more sense.

That one fails and gives the oops in __netif_schedule.
