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. cc: stable@vger.kernel.org # 6.6+ Fixes: d2689b6a86b9 ("net: usb: ax88179_178a: avoid two consecutive device resets") Reported-by: Dave Stevenson <dave.stevenson@raspberrypi.com> Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm@redhat.com> --- V1 -> V2: - Split the fix and the improvement in two patches as Simon Horman suggests. drivers/net/usb/ax88179_178a.c | 1 + 1 file changed, 1 insertion(+)
