invalid length of webkey that would/should be handled in mac80211?

Yes, it looks like.
Ummm, what has a wep key to do with me trying to access a WPA2-Personal
encrypted net ?
Not sure yet, but mac is trying to assign default/static wep key.
The output of wpa_supplicant with "-dddt" would be quite useful in
figuring this out.
The supplicant does always _clear_ static WEP keys when it starts the
interface, when a connection drops, and when it quits. Maybe that's
where it's coming from? But it should just be setting the "disabled"
bit in the WEXT structure and sending a key of all zeros.
