According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
egisters. This fixes an issue where the Ethernet link doesn't come up
when using ip link set down/up:

According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
egisters. 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
Fixes: f29cabf240ed ("arm64: dts: meson: use the generic Ethernet PHY reset GPIO bindings")

I have never experienced that myself but gotten a few reports about this.
thank you very much for coming up with info from the datasheet!
the following stmmac patch [0] has been added recently which may - or
may not - have any impact also.

According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
egisters. On similar boards with the same PHY this fixes an issue where
Ethernet link would not come up when using ip link set down/up.

According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
egisters. On similar boards with the same PHY this fixes an issue where
Ethernet link would not come up when using ip link set down/up.
