79e3efd5e5 net: phy: micrel: Disable B_CAST on config
Micrel PHYs KSZ8021/31 and KSZ8081 have a feature where MDIO address 0
is considered as a broadcast address; the PHY will respond even if it
is not its configured (pinstrapped) address. This feature is enabled
by default.

The Linux kernel disables that feature at initialisation, but not
before it probes the MDIO bus. This causes an issue, because a PHY
at address 3 will be discovered at addresses 0 and 3, but will then
only respond at address 3. Because Linux attaches the first PHY it
discovers on 'eth0', it will attach the PHY from address 0, which
will never answer again.

Fix the issue by disabling the broadcast feature in U-Boot, before
Linux is started.

This property allows to specify fastest connection mode supported by
the MAC (as opposed to features of the phy).

There are situations when phy may handle faster modes than the
MAC (or even it's particular implementation or even due to CPU being too
slow).

This property is a standard one in Linux kernel these days and some
boards do already use it in their device tree descriptions.

b884c3fe63 net/designware: do explicit port selection for 1Gb mode
Current implementation only sets "port select" bit for non-1Gb mode.
That works fine if GMAC has just exited reset state but we may as well
change connection mode in runtime. Then we'll need to reprogram GMAC for
that new mode of operation and if previous mode was 10 or 100 Mb and new
one is 1 Gb we'll need to reset port mode bit.

44bc317487 net: phy: genphy: Allow overwriting features
of_set_phy_supported allows overwiting hardware capabilities of
a phy with values from the devicetree. This does not work with
the genphy driver though because the genphys config_init function
will overwrite all values adjusted by of_set_phy_supported. Fix
this by initialising the genphy features in the phy_driver struct
and in config_init just limit the features to the ones the hardware
can actually support. The resulting features are a subset of the
devicetree specified features and the hardware features.

bbdcaff12a net: phy: ensure Gigabit features are masked off if requested
When a Gigabit PHY device is connected to a 10/100Mbits capable Ethernet
MAC, the driver will restrict the phydev->supported modes to mask off
Gigabit. If the Gigabit PHY comes out of reset with the Gigabit features
set by default in MII_CTRL1000, it will keep advertising these feature,
so by the time we call genphy_config_advert(), the condition on
phydev->supported having the Gigabit features on is false, and we do not
update MII_CTRL1000 with updated values, and we keep advertising Gigabit
features, eventually configuring the PHY for Gigabit whilst the Ethernet
MAC does not support that.

This patches fixes the problem by ensuring that the Gigabit feature bits
are always cleared in MII_CTRL1000, if the PHY happens to be a Gigabit
PHY, and then, if Gigabit features are supported, setting those and
updating MII_CTRL1000 accordingly.
