As previously mentioned in the msdu thread, I was seeing funky rates
at high speed when using my modified firmware and driver.
But, on my AP system, which is using standard firmware and standard
ath10k driver, I also see the rates show up improperly:
[root@ath10k-2220 lanforge]# cat /debug/ieee80211/wiphy1/netdev\:vap1/stations/04\:f0\:21\:0e\:38\:41/last_rx_rate
6.0 MBit/s
[root@ath10k-2220 lanforge]# cat /debug/ieee80211/wiphy1/netdev\:vap1/stations/04\:f0\:21\:0e\:38\:41/last_rx_rate
6.0 MBit/s
[root@ath10k-2220 lanforge]# cat /debug/ieee80211/wiphy1/netdev\:vap1/stations/04\:f0\:21\:0e\:38\:41/last_rx_rate
6.0 MBit/s
[root@ath10k-2220 lanforge]# cat /debug/ieee80211/wiphy1/netdev\:vap1/stations/04\:f0\:21\:0e\:38\:41/last_rx_rate
234.0 MBit/s
[root@ath10k-2220 lanforge]# cat /debug/ieee80211/wiphy1/netdev\:vap1/stations/04\:f0\:21\:0e\:38\:41/last_rx_rate
234.0 MBit/s
[root@ath10k-2220 lanforge]# cat /debug/ieee80211/wiphy1/netdev\:vap1/stations/04\:f0\:21\:0e\:38\:41/last_rx_rate
156.0 MBit/s
[root@ath10k-2220 lanforge]# cat /debug/ieee80211/wiphy1/netdev\:vap1/stations/04\:f0\:21\:0e\:38\:41/last_rx_rate
234.0 MBit/s
[root@ath10k-2220 lanforge]# cat /debug/ieee80211/wiphy1/netdev\:vap1/stations/04\:f0\:21\:0e\:38\:41/last_rx_rate
6.0 MBit/s
This system was sustaining almost 400Mbps TCP download throughput, so it
seems unlikely to me that the return rate would really be this low?
I'd be interested to know what others see for rates when running higher-speed throughput...
Thanks,
Ben

Hi, Ben
I did have a submitted patch to correct the last_rx_rate due to the
missing of VHT flag:

Maybe you can take a look on this.
