Michael Haas 525d187afb net: phy: Optionally force master mode for RTL PHY
This patch introduces CONFIG_RTL8211X_PHY_FORCE_MASTER. If this
define is set, RTL8211x PHYs (except for the RTL8211F) will have their
1000BASE-T master/slave autonegotiation disabled and forced to master
mode.

This is helpful for PHYs like the RTL8211C which produce unstable links
in slave mode. Such problems have been found on the A20-Olimex-SOM-EVB
and A20-OLinuXino-Lime2.

There is no proper way to identify affected PHYs in software as the
RTL8211C shares its UID with the RTL8211B. Thus, this fix requires
the introduction of an #ifdef.

bool "Ethernet PHY RTL8211x: force 1000BASE-T master mode"
depends on PHYLIB
help
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.
