driver attaches on top of the
driver to utilize one or more of its packet queues to create virtual
Ethernet network interface between the systems.
Typical MTU for the interface is about 64KB to reduce overhead.
Default MAC address for the interface is randomly generated.
driver does not implement any real hardware offload, but since PCIe link is
protected by CRC32, in some situations it may be possible to save some CPU
cycles by enabling fake checksum offload on both link sides via setting
