There is no standard API or kernel programming interface in Windows by
which an 802.11 driver can be asked to go into monitor mode; there
aren't even, as far as I know, documented driver-proprietary interfaces
to do that.

I'm not sure to which patch you're referring, but if you're referring to
Solomon Peachy's patch to handle the ARPHRD_IEEE80211_PRISM type in
Linux for the linux-wlan-ng Prism II driver, that patch is in 0.7.2.

What it does is, well, add support for the ARPHRD_ type that the
linux-wlan-ng driver for cards using the "Prism II" chipset uses for
monitor-mode captures.
