+Subject: [PATCH] net: usb: ax88179_178a: avoid the interface always configured
+ as random address
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+After the commit d2689b6a86b9 ("net: usb: ax88179_178a: avoid two
+consecutive device resets"), reset is not executed from bind operation and
+mac address is not read from the device registers or the devicetree at that
+moment. Since the check to configure if the assigned mac address is random
+or not for the interface, happens after the bind operation from
+usbnet_probe, the interface keeps configured as random address, although the
+address is correctly read and set during open operation (the only reset
+now).
+
+In order to keep only one reset for the device and to avoid the interface
+always configured as random address, after reset, configure correctly the
+suitable field from the driver, if the mac address is read successfully from
+the device registers or the devicetree. Take into account if a locally
+administered address (random) was previously stored.
