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.

Allocate the q_vectors individually. The advantage to this is that it
allows for easier freeing and allocation. In addition it makes it so
that we could do node specific allocations at some point in the future.

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.

The Tx "completed" stat was part of the original rewrite for detecting
Tx hangs. However some time ago in ixgbe I determined that we could
just use the packets stat instead. Since then this stat was
removed from ixgbe and it serves no purpose in i40e so it can be
dropped.
