Hi, I am using ath10k driver with qca988x hw2.0 and trying to limit it to use VHT MCS0-7 (iw set bitrates vht-mcs-5 2:0-7). But the command it causing a FW crash, if it disable HW_HAS_RATE_CONTROL no crash is observed but it still uses MCS9. tree: wireless-drivers-next: commit#535633a5ba4ea2504fa6c33176633becf0e59339 1) If i disable HW_RATE_CONTROL, will ath10k honor the mac80211 rates? 2) Please find below the dmesg after the crash.
