It seems it is necessary to set WILC MAC address after operation mode, otherwise the MAC address of the WILC MAC is reset back to what is in nvmem. This causes a failure to associate with AP after the WILC MAC address was overridden by userspace. Test case: " ap$ cat << EOF > hostap.conf interface=wlan0 ssid=ssid hw_mode=g channel=6 wpa=2 wpa_passphrase=pass wpa_key_mgmt=WPA-PSK EOF ap$ hostapd -d hostap.conf ap$ ifconfig wlan0 10.0.0.1 " " sta$ ifconfig wlan0 hw ether 00:11:22:33:44:55 sta$ wpa_supplicant -i wlan0 -c <(wpa_passphrase ssid pass) sta$ ifconfig wlan0 10.0.0.2 sta$ ping 10.0.0.1 # fails without this patch " AP still indicates SA with original MAC address from nvmem without this patch: " nl80211: RX frame da=ff:ff:ff:ff:ff:ff sa=60:01:23:45:67:89 bssid=ff:ff:ff:ff:ff:ff ... ^^^^^^^^^^^^^^^^^ " Fixes: 83d9b54ee5d4 ("wifi: wilc1000: read MAC address from fuse at probe") Tested-by: Alexis Lothoré <alexis.lothore@bootlin.com> Signed-off-by: Marek Vasut <marex@denx.de> --- Cc: Ajay Singh <ajay.kathat@microchip.com> Cc: Alexis Lothoré <alexis.lothore@bootlin.com> Cc: Claudiu Beznea <claudiu.beznea@tuxon.dev> Cc: Kalle Valo <kvalo@kernel.org> Cc: Marek Vasut <marex@denx.de> Cc: linux-wireless@vger.kernel.org Cc: stable@vger.kernel.org --- V2: Add TB, Fixes, CC Stable --- drivers/net/wireless/microchip/wilc1000/netdev.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-)
