I have an ioctl that tells the card how frequently to send out a
probe request, and I have an ioctl to fetch the last poll results
from the card.

That's the SSID, which is common for a service group. It's
transmitted in the beacon packet.
The access point name itself is a different beast, and has to be
probed for, so of course one can only probe for access points you
have the WEP key for, or which have WEP disabled.

I'd like to have a device (/dev/wi0 or something) that can be used as
a method to pass data into and out of the kernel. I'd use this as a
way to pass along packets that perhaps I don't want to send to the
IP stack (management, encrypted or undecryptable frames, etc) as
well as a general purpose async notification pipe for monitoring
AP associations, signal strengths, etc.
Does this make sense perhaps?
