Some boards need to change the tx/rx delay config in order for
gigabit Ethernet to work.
In Linux commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx
delay config"), Realtek documented the bits for overriding the delays
from the hardware straps.
Copy the logic from linux, so the delay config is set from the PHY's
interface type (the phy-mode property in the device tree).
This removes the need for a one-off workaround for the Pine A64+ board.

Force master mode for 1000BASE-T on RTl8211x PHYs (except for RTL8211F).
|
|
This can work around link stability and data corruption issues on gigabit
|
|
links which can occur in slave mode on certain PHYs, e.g. on the
|
|
RTL8211C(L).
|
|
|
|
Please note that two directly connected devices (i.e. via crossover cable)
|
|
will not be able to establish a link between each other if they both force
|
|
master mode. Multiple devices forcing master mode when connected by a
|
|
network switch do not pose a problem as the switch configures its affected
|
|
ports into slave mode.
|
|
|
|
This option only affects gigabit links. If you must establish a direct
|
|
connection between two devices which both force master mode, try forcing
|
|
the link speed to 100MBit/s.
|
|
|
|
If unsure, say N.

|
|
help
|
|
The IEEE 802.3az-2010 (EEE) standard provides a protocol to coordinate
|
|
transitions to/from a lower power consumption level (Low Power Idle
|
|
mode) based on link utilization. When no packets are being
|
|
transmitted, the system goes to Low Power Idle mode to save power.
|
|
|
|
Under particular circumstances this setting can cause issues where
|
|
the PHY is unable to transmit or receive any packet when in LPI mode.
|
|
The problem is caused when the PHY is configured to stop receiving
|
|
the xMII clock while it is signaling LPI. For some PHYs the bit
|
|
configuring this behavior is set by the Linux kernel, causing the
|
|
issue in U-Boot on reboot if the PHY retains the register value.
|
|
|
|
Default n, which means that the PHY state is not changed. To work
|
|
around the issues, change this setting to y.
