Manfred Rudigier 72092cc453 dp83640: Fix NOHZ local_softirq_pending 08 warning
Similar problem as in 481a819914 ("can:
fix NOHZ local_softirq_pending 08 warning"). This fix replaces
netif_rx() with netif_rx_ni() which has to be used from
process/softirq context.

Timur Tabi eb8a54a78e phylib: introduce mdiobus_alloc_size()
Introduce function mdiobus_alloc_size() as an alternative to mdiobus_alloc().
Most callers of mdiobus_alloc() also allocate a private data structure, and
then manually point bus->priv to this object.  mdiobus_alloc_size()
combines the two operations into one, which simplifies memory management.

The original mdiobus_alloc() now just calls mdiobus_alloc_size(0).

Andy Fleming fddf86fc46 phylib: Modify Vitesse RGMII skew settings
The Vitesse driver was using the RGMII_ID interface type to determine if
skew was necessary.  However, we want to move away from using that
interface type, as it's really a property of the board's PHY connection.
However, some boards depend on it, so we want to support it, while
allowing new boards to use the more flexible "fixups" approach.  To do
this, we extract the code which adds skew into its own function, and
call that function when RGMII_ID has been selected.

Another side-effect of this change is that if your PHY has skew set
already, it doesn't clear it.  This way, the fixup code can modify the
register without config_init then clearing it.

Richard Cochran ae6e86b7fb dp83640: drop PHY status frames in the driver.
The dp83640 PHY provides time stamp and other information via special
PHY status frames. Previously, the driver decoded the frames and then
let the network stack drop them. This works fine when the PTP messages
come over UDP.

However, when receiving PTP messages via L2 packets, this creates a
problem. The status frames use the official PTP destination MAC address,
and so they are delivered to user space along with the "real" frames,
causing confusion for applications.

This commit fixes the issue by simply dropping the PHY status frames
in the driver.

call their own ethtool get_settings()/mii_ethtool_gset(). The changes

Peter Korsgaard af1dc13e60 phylib: SIOCGMIIREG/SIOCSMIIREG: allow access to all mdio addresses
phylib would silently ignore the phy_id argument to these ioctls and
perform the read/write with the active phydev address, whereas most
non-phylib drivers seem to allow access to all mdio addresses
(E.G. pcnet_cs).

Grant Likely 74888760d4 dt/net: Eliminate users of of_platform_{,un}register_driver
Get rid of users of of_platform_driver in drivers/net.  The
of_platform_{,un}register_driver functions are going away, so the
users need to be converted to using the platform_bus_type directly.

Baruch Siach d606ef3fe0 phy/micrel: add ability to support 50MHz RMII clock on KZS8051RNL
Platform code can now set the MICREL_PHY_50MHZ_CLK bit of dev_flags in a fixup
routine (registered with phy_register_fixup_for_uid()), to make the KZS8051RNL
PHY work with 50MHz RMII reference clock.
