Abstract: Packets received non-contiguously from a network are processed by a network interface controller by coalescing received packet payload into receive buffers on a receive buffer queue and writing descriptors associated with the receive buffers for a same flow consecutively in a receive completion queue. System performance is optimized by reusing a small working set of provisioned receive buffers to minimize the memory footprint of memory allocated to store packet data. The remainder of the provisioned buffers are in an overflow queue and can be assigned to the network interface controller if the small working set of receive buffers is not sufficient to keep up with the received packet rate. The receive buffer queue can be refilled based on either timers or when the number of buffers in the receive buffer queue is below a configurable low watermark.

Abstract: The present disclosure is directed to a unified device interface for a multi-bus system. In at least one embodiment, a system may comprise more than one data bus. Each data bus may be to convey data between an operating system (OS) and at least one device in the system, wherein a plurality of driver instances may facilitate interaction between the OS and a device via one or more of the data buses. In one embodiment, a main driver instance may be determined from the plurality of driver instances to present the device to the OS and coordinate operation of other driver instances. The other driver instances may map addresses in the memory of processing entities corresponding to each of the data buses and report these mappings to the main driver instance. Alternatively, a supervisory driver may be loaded to present the device and to control operation of the driver instances.

Abstract: Examples are disclosed for assigning a switch identification to data received at an input/output device coupled to a host device. In some examples, the data may be associated with a virtual station interface (VSI) for a virtual machine implemented at the host device. For these examples, a switch identification may be assigned to the data based on identification information for the data or an originator of at least a portion of the identification information. The assigned switch identification may then be used as part of a lookup table to determine one or more actions for processing the data at the input/output device. Other examples are described and claimed.

Abstract: Methods and apparatus for software-controlled active-backup mode of link aggregation for RDMA and virtual functions. A Network Interface Controller (NIC) includes hardware implementing first and second physical functions (PFs) including transmit and receive resources to support data transfers via first and second ports. A bonding group is created with the first and second PFs. The first PF as an active PF and used for primary data transfers while implementing the second PF as a backup PF. On a link or port failure of the active PF, the bonding group is reconfigured to employ transmit and receive resources of the backup PF such that those resources are shared with the active PF. Data transfers are then performed using the shared resources of the active PF and the backup PF. Embodiments may support RDMA data transfers using PF bonding and the solution may be implemented in virtualized environments including virtual machines (VMs) in a manner transparent to the VMs.

Abstract: Examples described herein relate to an apparatus including at least one memory and at least one processor communicatively coupled to the at least one memory, the at least one processor to: allocate a scheduler to an egress port and based on unavailability of an egress port, allocate the scheduler to a second egress port to cause any packet allocated to a transmit queue associated with the scheduler to be transmitted using the second egress port. In some examples, a system receives a packet at a port on a network interface, associates a port group with the packet, determines a receive queue for the packet, and copies the packet to the determined receive queue. The port group can be adjusted to remove the port or to add a second port.

Abstract: Techniques are described that can be used to enable a transfer of an operating system from one machine to another. The transfer permits the operating system to be available to the target machine at buffers that are accessible to one or more application or other logic. In some implementations, information related to an operating system migration is stored in a buffer that is accessible to an application that is to use the information and thereby avoids a copy of such information from an intermediate buffer to an application buffer.
