Commit d397f7c45b ("net: phy: micrel: Separate KSZ9000 drivers from
KSZ8000 drivers") separated the KSZ8xxx and KSZ90x1 drivers and warns
that you shouldn't select both of them due to a device ID clash between
the KSZ9021 and the KS8721, asserting that "it is highly unlikely for a
system to contain both a KSZ8000 and a KSZ9000 PHY". Unfortunately
boards like the SAMA5D3xEK do contain both types of PHY, but fortunately
the Linux Micrel PHY driver provides a solution by using different PHY
ID and mask values to distinguish these chips.
This commit contains the following changes:
- The PHY ID and mask values for the KSZ9021 and the KS8721 now match
those used by the Linux driver.
- The warnings about not enabling both drivers have been removed.
- The description for PHY_MICREL_KSZ8XXX has been corrected (these are
10/100 PHYs, not GbE PHYs).
- PHY_MICREL_KSZ9021 and PHY_MICREL_KSZ9031 no longer select PHY_GIGE
since this is selected by PHY_MICREL_KSZ90X1.
- All of the relevant defconfig files have been updated now that
PHY_MICREL_KSZ8XXX does not default to 'Y'.

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.

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.

There is nothing like autoneogation and so

on, the link is always up with fixed speed and fixed duplex-setting.
