A network interface controller includes a bus interface to couple the controller to a load-store domain bus (such as PCI-Express), the bus including header information to associate data on the bus with an originating operating system domain. The controller also includes transmit/receive logic to connect it to the network. Association logic is further provided to allow the controller to designate, and later lookup which destination MAC address (on the ethernet side) is associated with which operating system domain. Control Status Registers (CSR's) specific to an operating system domain are duplicated and made available for each domain. Descriptor Register files are also duplicated for each operating system domain. A number of direct memory access (DMA) engines are provided to improve throughput. |
