In particular, note both bits, as well as the comment for 
IEEE80211_RADIOTAP_RATE:

  * IEEE80211_RADIOTAP_RATE              uint8_t         500kb/s or index
  *
  *      Tx/Rx data rate.  If bit 0x80 is set then it represents an
  *      an MCS index and not an IEEE rate.

The BADFCS bit, and the comment for IEEE80211_RADIOTAP_RATE, but not the 
SHORTGI bit, are also in the NetBSD header:

OpenBSD has none of them.
