Since there were no objections, we have adopted the following radiotap
changes:

 1) Add the "bad FCS" flag to the flags field (field 1) with the bit
    number 6, i.e. mask 0x40. [1]
 2) Define the new RX flags field at field number 14, with the following
    definition:
     - field contents: a single 16-bit integer
     - field alignment: 2
     - define bit 0 (mask 0x0001) to be reserved (it was defined by some
       implementations as "bad FCS" which is in the flags field)
     - define bit 1 (mask 0x0002) of this field to mean "frame has bad
       PLCP"
     - all other bits (mask 0xfffc) shall be reserved for future
       assignment


I will take care to update the Linux implementation, any pointers on
where to send the wireshark patch would be appreciated.
