[0x0000000e]:

      In theory, that would be an indication that there's a radiotap "presence bit" that tcpdump doesn't know about, 
except that 0x0000000e has 3 bits set.

That's a bit number, not a bit, so it's a radiotap field with a bit number of 14.

It's the RX flags field:

        http://www.radiotap.org/defined-fields/RX%20flags

The value isn't fetched or printed, as tcpdump doesn't include any support for that bit.
