Abstract: Examples described herein relate to a network interface device. In some examples, the network interface device includes a device interface; a direct memory access (DMA) circuitry; a network interface; a processor; and circuitry to boot from a network source, obtain one or more boot images from said network source, and subsequently operate as a network boot server for at least one other device.

Abstract: A method is described. The method includes respectively adding respective identifiers of respective queues that provide packets to a CPU to a list in response to the respective queues being deemed quiet. The method includes, as a consequence of an interrupt having been generated in response to one of the respective queues having received a packet, removing the respective identifiers from the list and executing respective poll service handlers for the respective queues. The method includes disabling those of the respective poll service handlers and adding those of the respective identifiers back to the interrupt cause list for those of the respective queues that are again deemed quiet, while, continuing executing others of the respective poll service handlers for others of the respective queues that are not deemed quiet.

Abstract: Tenant support is provided in a multi-tenant configuration in a data center by a Physical Function driver communicating a virtual User Priority to a virtual traffic class mapper to a Virtual Function driver. The Physical Function driver configures the Network Interface Controller to map virtual User Priorities to Physical User Priorities and to enforce the Virtual Function's limited access to Traffic Classes. Data Center Bridging features assigned to the physical network interface controller are hidden by virtualizing user priorities and traffic classes. A virtual Data Center Bridging configuration is enabled for a Virtual Function, to provide access to the user priorities and traffic classes that are not visible to the Virtual Function that the Virtual Function may need.
