This patch does some refactoring work that I felt was needed after reviewing the changes recently submitted relating to the replacement of net_stats with netdev->stats. This patch essentially creates two different collections of stats. The first handles the adapter specific states and is stored in gstring_stats, and the second is for netdev specific stats and is stored in gstring_net_stats.

This patch makes it so that nics such as 82576 and newer can support more hardware queues when there are more than 4 cpus by combining a tx/rx queue pair onto one interrupt so that 8 queue pairs can be supported and thus allow for more queues.

The allocation failed and checksum error stats are currently kept as a global stat. If we end up allocating the queues to multiple netdevs then the global counter doesn't make much sense.

Since we are writting to the head/tail pointers frequently we might as well save ourselves some processing time by converting the head and tail offsets directly to pointers.

This patch removes the rx_ps_hdr_len which isn't really needed since we can now use rx_buffer_len less than 1K to indicate that we are in a packet split mode.

Counting packets with a good checksum can cause a significant amount of cache line bouncing due to the shared counter being written to by all of the queues.
