Public bug reported:

probles abuot the wifi,the topo is as follows:
             88w8897))))))))wirelessrouter))))))))88w8897
we have two devices which use the chip,when we test the throughput between the 
two devices, we found some probles:
1.the throughput of upload is much lower than the download,at the idel 
environment,the upload throughput is about 200Mbps but the download throughput 
is 350Mbps.
2.when we restart the device and test the throughput between the two 
devices,the upload throughput is very low at the first time,then it gos up to 
the normal value slowly,sometimes it can't, the value is between 1mbps  to 
10mbps.

so i want to know how can i fix the two probles,can you help me.

our platform is linux(arm64) ,kernel is 4.4.16  ,the motherboard is
rk3399
