I am testing the pcie + ar9280 (wifi) performance on the imx6sx board. Transmission performance is below 10Mbps. Therefore, when debugging, ath_isr () printk message of the Linux ath9k device driver is output, the transmission performance is more than 50Mbps.
1. Is the PCIe or ATH9K driver a problem?
2. What is the solution?
I need help.
