You should probably ask the WinPcap developers about this, as it's 
probably some low-level issue with NDIS or WinPcap (perhaps the NDIS 
stack can't handle the Prism header, as NDIS and the networking stack 
might be expecting Ethernet headers).

Note also that there's no way in NDIS to specify that a networking 
device has Prism headers, so there's no way for WinPcap to know that 
merely by using information from NDIS - assuming you can even arrange 
that Prism headers (or AVS headers, or radiotap headers) be present in 
the packet (which might not be the case, as per my parenthetical note in 
the previous paragraph), you'd have to modify WinPcap to somehow know 
that the driver is supplying them, so it can return the right DLT_ value.
