linux 5.0-rc1 shows following warning on bpi-r2/mt7623 bootup: [ 5.170597] WARNING: CPU: 3 PID: 1 at drivers/net/phy/phy.c:548 phy_start_aneg+0x110/0x144 [ 5.178826] called from state READY ....

Except you have a specific need you normally don't need to manually fiddle with this. - phy_start_aneg() is called implicitly by the phylib state machine, you shouldn't call it manually except you have a good excuse. - netif_carrier_on/netif_carrier_off in mtk_phy_link_adjust() isn't needed. It's done by phy_link_change() in phylib.
