From 2b3d7e12ec90264aa7d8377da8786edf3ab56465 Mon Sep 17 00:00:00 2001 From: David Lin Date: Fri, 15 Dec 2023 08:51:18 +0800 Subject: [PATCH] wifi: mwifiex: configure BSSID consistently when starting AP commit f0dd488e11e71ac095df7638d892209c629d9af2 upstream. AP BSSID configuration is missing at AP start. Without this fix, FW returns STA interface MAC address after first init. When hostapd restarts, it gets MAC address from netdev before driver sets STA MAC to netdev again. Now MAC address between hostapd and net interface are different causes STA cannot connect to AP. After that MAC address of uap0 mlan0 become the same. And issue disappears after following hostapd restart (another issue is AP/STA MAC address become the same). This patch fixes the issue cleanly.
