Fix up some checkpatch complaints that have crept in:
doubled words words, mispellled words, doubled lines.

These debug stats are not really useful, their collection is
likely detrimental to performance, and they suck up a lot
of memory which never gets used if no one ever enables the
priv-flag to print them, so just remove these bits.

Don't print stats for which we haven't reserved space as it can
cause nasty memory bashing and related bad behaviors.

Abstract out the per-queue data collection work into separate
functions from the per-queue loops in the stats reporting,
similar to what Alex did for the data label strings in

Update the ionic driver to make use of ethtool_sprintf. In addition add
separate functions for Tx/Rx stats strings in order to reduce the total
amount of indenting needed in the driver code.

linux/netdevice.h is included in very many places, touching any
of its dependecies causes large incremental builds.
Drop the linux/ethtool.h include, linux/netdevice.h just needs
a forward declaration of struct ethtool_ops.
Fix all the places which made use of this implicit include.

Use a block of stats structs attached to the lif instead of
little ones attached to each qcq. This simplifies our memory
management and gets rid of a lot of unnecessary indirection.

Add a counter for packets dropped by the driver, typically
for bad size or a receive error seen by the device.

When the netdev is down, the queues and their debug stats
do not exist, so don't try using a pointer to them when
when printing the ethtool stats.

Add in the detailed statistics for ethtool -S that the driver
keeps as it processes packets. Display of the additional
debug statistics can be enabled through the ethtool priv-flags
feature.
