Dear, Mr. Jiao! Recently, we have been trying to change the bandwidth of OpenWiFi from the default 20MHz to 10MHz. We have made modifications to six values in the rf_init_11n file, which allows us to achieve the desired bandwidth. However, during data transmission, we consistently see the following warning message in the dmesg output: "openwifi_tx:WARNING status!=DMA_COMPLETE." This issue often leads to disconnections in the upper layers. Based on our preliminary analysis, we suspect it is a flow control problem. We noticed that you encountered a similar issue in one of your earlier blog posts. Could you give me some advice for this problem? Thank you very much.
