[ Upstream commit c183c406c4321002fe85b345b51bc1a3a04b6d33 ]
According to the datasheet (Rev. 1.9) the RTL8211F requires at least 72ms "for internal circuits settling time" before accessing the PHY registers. This fixes an issue seen on ODROID-C2 where the Ethernet link doesn't come up when using ip link set down/up: [ 6630.714855] meson8b-dwmac c9410000.ethernet eth0: Link is Down [ 6630.785775] meson8b-dwmac c9410000.ethernet eth0: PHY [stmmac-0:00] driver [RTL8211F Gigabit Ethernet] (irq=36) [ 6630.893071] meson8b-dwmac c9410000.ethernet: Failed to reset the dma [ 6630.893800] meson8b-dwmac c9410000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed [ 6630.902835] meson8b-dwmac c9410000.ethernet eth0: stmmac_open: Hw setup failed
