In linux kernel since version 3.10 (release Date: 2013-06-30)  
This driver supports Thunder's NIC physical function.
The NIC provides the controller and DMA engines to
move network traffic to/from the memory. The NIC
works closely with TNS, BGX and SerDes to implement the
functions replacing and virtualizing those of a typical
standalone PCIe NIC chip.
