+Subject: [PATCH 1/2] net: ethernet: bgmac: use phydev from struct net_device
+
+The private structure contain a pointer to phydev, but the structure
+net_device already contain such pointer. So we can remove the pointer
+phydev in the private structure, and update the driver to use the
+one contained in struct net_device.

+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.
