For the umpity-umpth time: existing Windows NDIS drivers are implemented
using the 802.3 (ethernet) link type. They don't support monitor mode or
raw 802.11 frame formats, so it is not possible to implement radiotap
with them.

Any vendor that claims to let you read/send raw 802.11 frames with
their device has implemented a non-standard interface that falls outside
the NDIS API.
