+Subject: [PATCH 3/3] net: bgmac: Remove superflous netif_carrier_on()
+
+bgmac_open() calls phy_start() to initialize the PHY state machine,
+which will set the interface's carrier state accordingly, no need to
+force that as this could be conflicting with the PHY state determined by
+PHYLIB.
+
+Fixes: dd4544f05469 ("bgmac: driver for GBit MAC core on BCMA bus")
