Update Documentation/networking/mac80211-injection.txt to include the following 2 new flags: * IEEE80211_RADIOTAP_TX_FLAGS IEEE80211_RADIOTAP_F_TX_NO_ACK: Transmit the packet once with no waiting for an ACK and no retrying if no ACK received IEEE80211_RADIOTAP_F_TX_NO_SEQ: Use the sequence number already present in the 802.11 header, do not generate a new one in the driver/stack. Useful when injecting fragments with the same sequence number. In addition, update the language somewhat to stop refering to "three parameters" (there are more than 3, even without this patch).
