Linville" Subject: [RFC 0/3] cfg80211, mac80211: Introduce radiotap flags for finer userspace control of injection Cc: "Johannes Berg" , linux-wireless MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-wireless-owner@vger.kernel.org List-ID: Userspace packet injector applications might want to transmit packets that are, by design, not supposed to be acked. In other cases, an injector application may need to control the sequence number of the packets it transmits. Introduce 2 new flags in the "TX flags" Radiotap fields, controlling these 2 behaviors. The new fields are as follows: * IEEE80211_RADIOTAP_TX_FLAGS IEEE80211_RADIOTAP_F_TX_NO_ACK: Transmit the packet once with no wai= ting for an ACK and no retrying if no ACK received IEEE80211_RADIOTAP_F_TX_NO_SEQ: Use the sequence number already pres= ent in the 802.11 header, do not generate a new one in the driver/stack. Useful when injecting fragments with the same sequence number.
