Bug Description
recently when we use the chip 88w8897 ,we found that there were some probles abuot the wifi,the topo is as follows:
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.
