Hi.
I've made a software to inject packets on Wi-Fi, like packet spammer, and
created a packet with RadioTap Header + eth frame + FCS and wrote it to
mon0 interface, created from wlan0 (Ad-Hoc at 5 GHz with PSK2), in order
to send that packet with a specific bitrate, overriding auto or fixed
bitrate mechanisms from mac80211 / minstrel_ht.
At transmiter, capturing packet with tcpdump+wireshark, the field "MCS
index" of "MCS information" show value of 8, which is the value that I did
set in the packet before sending. Although, at receiving station, the same
capture show that that value as been overridden to 5 and the packet was
received at bitrate different that it was supposed to.
The wireless card that I'm using supports packet injection and this was
supposed to work.
Also, when do command line 'iw dev wlan0 set noack_map 0x0009', the packet
is received at basic rate, not at MCS 8 (using 2 streams).
Tested at r43000, ath9k, ar9220.
Thanks.
