Add a quick ethtool test for interrupts using the SW interrupt.
Also, change the loopback test (for now) to not report failure.

The version bits reported by the hardware changed, so fix
up the offsets to print the version correctly.

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.
