Mitch Williams 54692b403c i40e: allow one more vector for VFs
The number of vectors per VF as reported by the hardware does not
include vector 0, so we need to account for this when checking to
see if the VF is configuring a valid vector.

This change brings support for 64 bit netstats to the driver. Previously
the stats were 64 bit but highly racy due to the fact that 64 bit
transactions are not atomic on 32 bit systems.  This change makes is so

Alexander Duyck 9f65e15b4f i40e: Move rings from pointer to array to array of pointers
Allocate the queue pairs individually instead of as a group.  This
allows for much easier queue management as it is possible to dynamically
resize the queues without having to free and allocate the entire block.

Ease statistic collection by treating Tx/Rx queue pairs as a single
unit.  Each pair is allocated together and starts with a Tx queue and
ends with an Rx queue.  By ordering them this way it is possible to know
the Rx offset based on a pointer to the Tx queue.

Alexander Duyck a114d0a6ac i40e: Split bytes and packets from Rx/Tx stats
This makes it so that the Tx and Rx byte and packet counts are
separated from the rest of the statistics.  This allows for better
isolation of these stats when we move them into the 64 bit statistics.

Simplify things by re-ordering how the stats display in ethtool.
Instead of displaying all of the Tx queues as a block, followed by all
the Rx queues, the new order is Tx[0], Rx[0], Tx[1], Rx[1], ..., Tx[n],
Rx[n].  This reduces the loops and cleans up the display for testing
purposes since it is very easy to verify if flow director is doing the
right thing as the Tx and Rx queue pair are shown in pairs.

Alexander Duyck fc4ac67bc9 i40e: Do not directly increment Tx next_to_use
Avoid directly incrementing next_to_use for multiple reasons.  The main
reason being that if we directly increment it then it can attain a state
where it is equal to the ring count.  Technically this is a state it
should not be able to reach but the way this is written it now can.

This patch pulls the value off into a register and then increments it
and writes back either the value or 0 depending on if the value is equal
to the ring count.
