Hi everyone.
When using frame injection over monitor interface, with handmade
packet with Radiotap header + QoS + Data, at sender I capture the
packet with tcpdump and it is equal to the one I sent.
Although, at receiver station, the packet is diferent, FCS was
recalculated or forced to active and calculated, MCS is not the one I
supplied, sequence number (QoS field) is not the same, amongst other
things.
Also, QoS Ack policy was "No Ack" at sender (QoS Control = 0x0020), a
Ack frame was transmitted to sender and the received packet arrived
with QoS Control = 0x0000.
Tested with Microtik R52n-M (AR9220) on following operating systems:
- AP-STA using Ubuntu Ubuntu 14.04.1 LTS;
- AdHoc using OpenWRT r43000, with kmod-ath9k version
3.10.49+2014-11-04-1 and kmod-mac80211 version 3.10.49+2014-11-04-1.
Regarding to OpenWRT, this malfunction was reported here:

Thanks.
