First I apologize as I forgot to mention I am putting the channel into
HT40 mode and the frames coming in are non-HT as that is the stated that
the issue was reported to me. I have not ran test yet to see if it
occurs with the channel in HT20 and non-ht mode. Also I have one more
test to run on compat-wireless-3.0-2 but it looks like I am not seeing
any issue with it.
For reference here is the patch from my change, very similar to yours
except that I didn't dump signal or noise.
@@ -1015,6 +1015,8 @@ static int ath9k_rx_skb_preprocess(struct
ath_common *common,
rx_status->snr = rx_stats->rs_rssi;
rx_status->antenna = rx_stats->rs_antenna;
rx_status->flag |= RX_FLAG_MACTIME_MPDU;
+ if (rx_stats->rs_rssi > 95 || rx_stats->rs_rssi < 0)
+ printk("[ath9k]: RSSI %hhd\n", rx_stats->rs_rssi);
return 0;
}
I will rerun it with your additions so you can see those values as well.
Yes I can also test it with a nightly package to see if it has been
resolved.
Thanks for the Help!
