f0528ce7a4 net: greth: use phy_read_status()
In case the greth driver is bound to anything but the Generic PHY
driver or the PHY has a special read_status callback implemented,
unexpected things will happen. Make sure we that we use
phy_read_status() which does the proper abstraction of calling the
driver specific read_status() callback for a given PHY.

====================
Intel Wired LAN Driver Updates

This series contains updates to i40e only.

Jacob provides a i40e patch to get 1588 work correctly by separating
TSYNVALID and TSYNINDX fields in the receive descriptor.

Jesse provides several i40e patches, first to correct the checking
of the multi-bit state.  The hash is reported correctly in the RSS
field if and only if the filter status is 3.  Other values of the
filter status mean different things and we should not depend on a
bitwise result.  Then provides a patch to enable a couple of
workarounds based on revision ID that allow the driver to work
more fully on early hardware.

Shannon provides several i40e patches as well.  First sets the media
type in the hardware structure based on the external connection type.
Then provides a patch to only setup the rings that will be used.  Lastly
provides a fix where the TESTING state was still set when exiting the
ethtool diagnostics.

Kevin Scott provides one i40e patch to add a new flag to the i40e_add_veb()
which allows the driver to request the hardware to filter on layer 2
parameters.

Anjali provides four i40e patches, first refactors the reset code in
order to re-size queues and vectors while the interface is still up.
Then provides a patch to enable all PCTYPEs expect FCoE for RSS.  Adds
a message to notify the user of how many VFs are initialized on each
port.  Lastly adds a new variable to track the number of PF instances,
this is a global counter on purpose so that each PF loaded has a
unique ID.

Catherine bumps the driver version.

We also need to reset the existing setup, update the

'max-speed' is supposed to set a PHY device supported features, not the

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates

This series contains updates to i40e only.

Christopher Pau provides a patch to set pf_id based on device and
function numbers since NICs with ARI enabled can have function
numbers larger than 8.

Anjali provides 3 i40e patches to update hardware defines to keep
in sync with hardware updates.

Shannon provides the majority of i40e patches, with 7.  First patch
clears the admin queue head and tail registers during admin queue
shutdown. Then simplifies the admin queue head-tail-len setups to
use more virtual registers.  Provides several patches to cleanup
and fix driver load and reset procedures to make more robust.  Lastly,
provides an ethtool test for interrupts using the software interrupt.

Mitch provides some i40e patches which fixes up VF code in the PF
driver, specifically the number of vectors per VF are reported by the
hardware does not include vector 0, so we need to account for this
when checking.  In addition, cleans up debugging messages.

Kamil provides an i40e patch to fix the diagnostics test by restricting
the diagnostic test length.

0ab75ae81d ethernet: Fix FSF address in file headers
Several files refer to an old address for the Free Software Foundation
in the file header comment.  Resolve by replacing the address with
the URL <http://www.gnu.org/licenses/> so that we do not have to keep
updating the header comments anytime the address changes.
