The driver was converted to use snprintf everywhere but this one function.
Just use snprintf, instead of sprintf.

Also a small spelling correction in a comment.

The loop in i40evf_get_rxfh_indir was only reading fifteen registers,
not all sixteen. Change the matching loop in i40evf_set_rxfh_indir at
the same time to make the code more consistent.

from the chip design.

i40evf_set_ringparam was broken in several ways. First, it only changed
the size of the first ring, and second, changing the ring size would
often result in a panic because it would change the count before
deallocating resources, causing the driver to either free nonexistent
buffers, or leak leftover buffers.

Fix this by storing the descriptor count in the adapter structure, and
updating the count for each ring each time we allocate them. This
ensures that we always free the right size ring, and always end up with
the requested count when the device is (re)opened.

ETHTOOL_{G,S}RXFHINDIR and ETHTOOL_{G,S}RSSH should work for drivers
regardless of whether they expose the hash key, unless you try to
set a hash key for a driver that doesn't expose it.

For all of our supported kernels, ethtool allows us to directly control
adaptive ITR instead of just faking it with an ITR value. Support this
capability so that user knows explicitly when ITR is being controlled
dynamically. Suggested by Ben Hutchings.

Don't tell ethtool that the VF can do 10GbaseT, when it really has no
idea what its link speed is. Set the supported values to 0 instead.

net: get rid of SET_ETHTOOL_OPS

Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.
This does that.

Mostly done via coccinelle script:
@@
struct ethtool_ops *ops;
struct net_device *dev;
@@
- SET_ETHTOOL_OPS(dev, ops);
+ dev->ethtool_ops = ops;

Compile tested only, but I'd seriously wonder if this broke anything.

Add support for getting and setting RSS hashing options, RSS LUT
entries, and getting the number of device channels from ethtool. Because
the LUT is so small for the VFs, we just read and write the device
registers directly instead of maintaining a shadow copy.

the i40e PF driver.

This patch contains the ethtool interface and related functionality.
Since the VF driver is mostly unaware of link, much of that
functionality is unused. The driver implements ethtool hooks for
statistics, driver info, and some basic non-link-related driver
settings.
