Javier Achirica posted some patches to airo.c and libpcap to the aironet
mailing list. They work against Ben Reed's aironet driver in the pcmcia-cs
package.

An earlier version is at:

The earlier post says the patches are to be used against version 1.7 of
Ben's driver from the CVS repository. I've successfully applied the patches
and got my aironet card into monitor mode. It won't return the aironet frame
headers, but you will see all 802.11 frames with headers. The driver needs
modified further to return the aironet headers, which have information like channel,
signal strength, transmission rate, etc.
