ce0b15d110 xgbe: constify get_netdev_ops and get_ethtool_ops
Casting away const is bad practice. Since this is ARM specific driver
don't have hardware actually test this.

Having getter functions for ops is really unnecessary code bloat, but
not going to touch that.

7c12aa0877 amd-xgbe: Move the PHY support into amd-xgbe
The AMD XGBE device is intended to work with a specific integrated PHY
and that PHY is not meant to be a standalone PHY for use by other
devices. As such this patch removes the phylib driver and implements
the PHY support in the amd-xgbe driver (the majority of the logic from
the phylib driver is moved into the amd-xgbe driver).

Update the driver version to 1.0.1.

8dee19e619 amd-xgbe: Allow rx-frames coalescing to be changed anytime
Currently the device must be down in order to update the rx-frames
coalescing setting because the interrupt indicator is set in the
descriptor data during initialization. Allow this setting to be changed
while the device is up by moving the interrupt decision into the
descriptor reset function and base the decision off of the supplied
descriptor index value.

4a57ebcc2c amd-xgbe: Fix Rx coalescing reporting
The Rx coalescing value is internally converted from usecs to a value
that the hardware can use. When reporting the Rx coalescing value, this
internal value is converted back to usecs. During the conversion from
and back to usecs some rounding occurs. So, for example, when setting an
Rx usec of 30, it will be reported as 29. Fix this reporting issue by
keeping the original usec value and using that during reporting.

c635eaacbf amd-xgbe: Remove Tx coalescing
The Tx coalescing support in the driver was a software implementation
for something lacking in the hardware. Using hrtimers, the idea was to
trigger a timer interrupt after having queued a packet for transmit.
Unfortunately, as the timer value was lowered, the timer expired before
the hardware actually did the transmit and so it was racey and resulted
in unnecessary interrupts.

Remove the Tx coalescing support and hrtimer and replace with a Tx timer
that is used as a reclaim timer in case of inactivity.

892311f66f ethtool: Support for configurable RSS hash function
This patch extends the set/get_rxfh ethtool-options for getting or
setting the RSS hash function.

It modifies drivers implementation of set/get_rxfh accordingly.

This change also delegates the responsibility of checking whether a
modification to a certain RX flow hash parameter is supported to the
driver implementation of set_rxfh.

User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.

Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.
