This is probably not the best forum (being related to kernel dev) - hit
me up on personal email or on the kismet forum for Kismet-specific
stuff...

This mirrors my own experience with many of the mac80211 drivers in
their development status, which is that they typically return only
mgmt (or sometimes only beacon) frames.

I've held off complaining since I know the drivers are in a pretty heavy
dev state right now, however if it's useful I'll start throwing cards
into rfmon and reporting what happens. Kismet and tcpdump use the same
data, so anyone who doesn't feel like getting Kismet going for rfmon
testing can obviously just throw the card into rfmon and tcpdump it, if
mgmt and data frames show up, I'll be happy :)
I can currently say that iwl4965, 2.6.24.3, rfmon returns no packets at
all. In wireless-testing head as of 2 days ago, rfmon threw the card
into sw-rfkill, then got into a thrash where it couldn't find the
firmware anymore, and then kernel paniced the system. Maybe tonight
I'll try again and post more logs, I'll include the errors at the time but
readily admit that since they're not from the wireless-test head they're
probably not incredibly useful.
