The following updates are included in this driver update series:
- Set the MDIO mode to clause 45 for the 10GBase-T configuration
- Set the MII control width to 8-bits for speeds less than 1Gbps
- Fix an issue to related to module removal when the devices are up
- Fix ethtool statistics related to packet counting of TSO packets
- Add support for device renaming
- Add additional dynamic debug output for the PCS window calculation
- Optimize reading of DMA channel interrupt enablement register
- Add additional dynamic debug output about the hardware features
- Add per queue Tx and Rx ethtool statistics
- Add a macro to clear ethtool_link_ksettings modes
- Convert the driver to use the ethtool_link_ksettings
- Add support for VXLAN offload capabilities
- Add additional ethtool statistics related to VXLAN
This patch series is based on net-next.

Currently the MDIO mode is set to none for the 10000Base-T, which is
incorrect. The MDIO mode should for this configuration should be
clause 45.

When running in SGMII mode at speeds below 1000Mbps, the auto-negotition
control register must set the MII control width for the MAC interface
to be 8-bits wide. By default the width is 4-bits.

Sometimes when the driver is being unloaded while the devices are still
up the driver can issue errors. This is based on timing and the double
invocation of some routines. The phy_exit() call needs to be run after
the network device has been closed and unregistered from the system.
Also, the phy_exit() does not need to invoke phy_stop() since that will
be called as part of the device closing, so remove that call.

When transmitting a TSO packet, the driver only increments the TSO packet
statistic by one rather than the number of total packets that were sent.
Update the driver to record the total number of packets that resulted from
TSO transmit.

Many of the names used by the driver are based upon the name of the device
found during device probe. Move the formatting of the names into the
device open function so that any renaming that occurs before the device is
brought up will be accounted for. This also means moving the creation of
some named workqueues into the device open path.
Add support to register for net events so that if a device is renamed
the corresponding debugfs directory can be renamed.

Add some additional dynamic debug message to the driver. The new messages
will provide additional information about the PCS window calculation.

Currently whenever the driver needs to enable or disable interrupts for
a DMA channel it reads the interrupt enable register (IER), updates the
value and then writes the new value back to the IER. Since the hardware
does not change the IER, software can track this value and elimiate the
need to read it each time.
Add the IER value to the channel related data structure and use that as
the base for enabling and disabling interrupts, thus removing the need
for the MMIO read.

To: netdev; +Cc: David Miller
The hardware has the capability to perform checksum offload support
(both Tx and Rx) and TSO support for VXLAN packets. Add the support
required to enable this.
The hardware can only support a single VXLAN port for offload. If more
than one VXLAN port is added then the offload capabilities have to be
disabled and can no longer be advertised.
