Subject: [PATCH 0/2] net: phy: realtek: fix RTL8211F TX-delay handling

The RTL8211F PHY driver currently enables the TX-delay only when the
phy-mode is PHY_INTERFACE_MODE_RGMII. This is incorrect, because there
are three RGMII variations of the phy-mode which explicitly request the
PHY to enable the RX and/or TX delay, while PHY_INTERFACE_MODE_RGMII
specifies that the PHY should disable the RX and/or TX delays.

Additionally to the RTL8211F PHY driver change this contains a small
update to the phy-mode documentation to clarify the purpose of the
RGMII phy-modes.
While this may not be perfect yet it's at least a start. Please feel
free to drop this patch from this series and send an improved version
yourself.

These patches are the results of recent discussions, see [0]
