No, I mean all 802.11 frames are encapsulated in 802.3 frames by our firmware. We use this to pass these frames up in Windows with winpcap (or any other OS).

...and presumably the only packets that are captured are data packets,
so there's not much information lost by using the fake 802.3 headers.
If he wants to see more than just data packets, such as management
packets, he'll have to capture in monitor mode; the Ethereal FAQ entry I
sent him earlier discusses how to do so in Linux.
