If anyone has any objections, please let me know. ------------------ From: Chin-Yen Lee [ Upstream commit 37c23874d13eb369d8b384a1ce5992ff6c23d56f ] In scheduled scan mode, the current probe request only includes the SSID IE, but omits the Basic Rate IE. Some APs do not respond to such incomplete probe requests, causing net-detect failures. To improve interoperability and ensure APs respond correctly, add the Basic Rate IE to the probe request in driver.
