Though the spec defines these as one bit value, they are usually referred
as combined value. So I'd prefer to treat two bit value as follows:
#define IEEE80211_FC1_DIR_MASK 0x03
#define IEEE80211_FC1_DIR_NODS 0x00 /* STA -> STA */
#define IEEE80211_FC1_DIR_TODS 0x01 /* STA -> AP */
#define IEEE80211_FC1_DIR_FROMDS 0x02 /* AP -> STA */
#define IEEE80211_FC1_DIR_DSTODS 0x03 /* AP -> AP */
If there are no objections, I (or perhaps enami-san) will commit the
changes above with some additional definitions of management frame,
which are necessary for awi (PCnetMOBILE) driver.

It will be fixed with the modifications, while I (no one?) cannot
