This patchset contains a few improvements to the MDIO device tree parsing

The ARC emac driver was the only in-tree to parse a PHY device
'max-speed' property but yet failed to do it correctly because
'max-speed' is supposed to set a PHY device supported features, not the
advertising features as it was done.

Now that of_mdiobus_register() takes care of doing that, remove the
custom 'max-speed' parsing code.

The "max-speed" property is defined per the ePAPR specification to
express the maximum speed a PHY supports. Use that property, if present
to set the phydev->supported features which properly restricts the PHY
within the range of defined speeds.

If irq_of_parse_and_map fails to find an interrupt line for a given PHY,
we will force the PHY interrupt to be PHY_POLL, completely overriding

PHY_IGNORE_INTERRUPT). In case of failure, just restore the previous
value.

Since commit 779d835e ("net: of_mdio: scan mdiobus for PHYs without reg

thing. Factor the PHY device registration in a function helper:
of_mdiobus_register_phy() which takes care of the details and allows for
future PHY specific extensions.

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.

With the introduction of TCP Small Queues, TSO auto sizing, and TCP
pacing, we can implement Automatic Corking in the kernel, to help
applications doing small write()/sendmsg() to TCP sockets.

Idea is to change tcp_push() to check if the current skb payload is
under skb optimal size (a multiple of MSS bytes)

If under 'size_goal', and at least one packet is still in Qdisc or
NIC TX queues, set the TCP Small Queue Throttled bit, so that the push
will be delayed up to TX completion time.

This delay might allow the application to coalesce more bytes
in the skb in following write()/sendmsg()/sendfile() system calls.

The exact duration of the delay is depending on the dynamics
of the system, and might be zero if no packet for this flow
is actually held in Qdisc or NIC TX ring.

Using FQ/pacing is a way to increase the probability of
autocorking being triggered.

Add a new sysctl (/proc/sys/net/ipv4/tcp_autocorking) to control
this feature and default it to 1 (enabled)

Add a new SNMP counter : nstat -a | grep TcpExtTCPAutoCorking
This counter is incremented every time we detected skb was under used
and its flush was deferred.

Tested:

Interesting effects when using line buffered commands under ssh.

Excellent performance results in term of cpu usage and total throughput.
