BugLink: http://bugs.launchpad.net/bugs/1692836 The fix is suggested by Qualcomm, and it helps to fix the network speed issue. Ath10k driver changed a lot after 4.4 kernel, so this fix can't applied on other kernels than 4.4. We need to figure out other way for kernels after Xenial. Without the patch, the 5GHz network speed is pretty low 11n 0.0-120.1 sec 271 MBytes 18.9 Mbits/sec 11AC 0.0-120.2 sec 141 MBytes 9.86 Mbits/sec After applied the patch 11n 0.0-120.0 sec 2.04 GBytes 146 Mbits/sec 11AC 0.0-120.0 sec 1.17 GBytes 83.6 Mbits/sec Signed-off-by: AceLan Kao <acelan.kao@canonical.com> --- drivers/net/wireless/ath/ath10k/mac.c | 2 ++ 1 file changed, 2 insertions(+)
