When the phy address is 31, this means that there is no PHY connected
to this MAC at all, no internal and no external PHY. Reading these PHY
registers causes a system reset on some routers.

The PHY address 30 means there is no local PHY, but there could be an
external PHY like a switch connected via MII. This is the case on most
embedded home routers where this driver is used.

The Ethernet core supported by b44 supports an internal PHY integrated
into the mac core, which is supported by the b44 driver and an external
PHY to which the mac core is connected. This external PHY could be a
switch connected through MII, which is often the case when this core is
used on home routers. The usage of an external PHY was assumed when the
PHY address 30 was used and an internal PHY was assumed when the PHY
address was different. To verify that b44_phy_reset() was called and
checked if it worked, otherwise PHY address 30 was assumed, an external
PHY. It is better to check the register which says which PHY is
connected to the MAC instead of checking the PHY address.
The interface to an external PHY was only activated when this register
was set.
This also changes B44_FLAG_INTERNAL_PHY to B44_FLAG_EXTERNAL_PHY, it is
easier to check.

There's no need anymore to call phy_init_hw() to reset/resume the PHY from the
driver, as the call chain in phylib already has reached it, and so reset/resumed
the PHY (even resuming it twice). This duplicate reset is not only needless, it
e.g. clears the PHY's interrupt enables just setup by phylib and so prevents the
expected IRQs from the PHY.

To achieve out of the box performance default is to use 64 byte CQE/EQE.

Add the infrastructure needed to support ndo_get_phys_port_id which
allows users to identify to which physical port a net-device is connected
to by reading a unique port id.
This will work for VFs and PFs.
The driver uses a new device capability - phys_port_id, The PF driver
reads the port phys_port_id from Firmware and stores it. The VF driver
reads the port phys_port_id from the PF using QUERY_FUNC_CAP command.

netback already has code which parses IPv4 and v6 headers to set up checksum
offsets and these are always applied to GSO packets being sent from
frontends. It's therefore suboptimal that GSOs are being marked
SKB_GSO_DODGY to defer the gso_segs calculation when netback already has all
necessary information to hand to do the calculation. This patch adds that
calculation.

Intel Wired LAN Driver Updates
This series contains updates to i40e, ixgbevf, ixgbe and igb.
Don provides an ixgbevf patch to add DCB configuration into the queue
setup so that we won't have to allocate queues in a separate place when
enabling DCB.
Guenter Roeck provides 2 patches for ixgbe to simplify the code by
attaching hwmon sysfs attributes to hwmon device instead of PCI device.
Also fix an issues where the temperature sensor attribute index was
being started with the value 0 and not 1 as per the hwmon API.
Carolyn provides igb patches to fix queue allocation method to
accommodate changes during runtime. This includes changing how the
driver initializes MSIx and checks for MSIx configuration to make it
easier to reconfigure the device when queue changes happen at runtime.
Neerav and Shannon fixes i40e debugfs commands that dump hex information
by using print_hex_dump().
Shannon provides several i40e fixes which include the prevention of
null pointer exception in the dump descriptor by checking that rings
were allocated before trying to reference them. Fixed up a couple of
scanfs to accept various base numbers instead of silently requiring hex.
Anjali fixes up i40e where the incorrect defines were being used for
misc interrupts.
Alan Cox provides a fix for i40e where we assume that the resulting
buffer is zero terminated when we then re-use it. The sscanf is limited
to 512 bytes but needs to be 511 to allow for a terminator.
Stephen Hemminger fixes i40e by making local functions static and removes
unused code (i40e_aq_add/remove_vlan() functions).

When changing number of queues using ethtool's set_channels during runtime,
a queue allocation could fail, which can leave the device in a down state.
In order to preserve the usability of the device in this scenario, this patch
changes the driver to allocate the number of queues only if they have not
been allocated already. The first allocation is then done for the max number
of queues, which is the default queues for this driver. With this change,
queue quantity changes are not subject to queue allocation failures.

Simplify the code. Attach hwmon sysfs attributes to hwmon device
instead of pci device. Avoid race conditions caused by attributes
being created after hwmon device registration. Implicitly
(through hwmon API) add mandatory 'name' sysfs attribute.
Other cleanup:
Instead of allocating memory for hwmon attributes, move attributes
and all other hwmon related data into struct hwmon_buff and allocate
the entire structure using devm_kzalloc.
Check return value from calls to igb_add_hwmon_attr() one by one instead
of logically combining them all together.
