Update tx/rx stats locally, so that ndo_get_stats64()
can use that and not rely on per queue resources to obtain statistics.
The latter used to cause race conditions when the device stopped.

Inquire firmware on supported offloads, as well as convey offloads
enabled dynamically to firmware. New control net API functionality is
required for the above. Implement control net API framework for
offloads.
Additionally, fetch/insert offload metadata from hardware RX/TX
buffer respectively during receive/transmit.
Currently supported offloads include checksum and TSO.
