    摘要: In link aggregation configurations, a data packet may be copied into a buffer space of a first NIC. Load balancing techniques may determine that the packet should be transmitted by a second NIC. The packet exists in memory that the second NIC cannot access. The data packet is copied into memory accessible to the second NIC or the memory location of the packet is registered with the NIC. A copy penalty is incurred if a packet is copied from a first buffer space to a second buffer space. A registration penalty is incurred if the location within the first buffer space is registered with the second NIC. Functionality can be implemented within a link aggregation configuration to register buffer space shared among interconnected NICs. Sharing of buffer space between interconnected NICs allows any one of the NICs to access data within the shared buffer space without incurring a penalty.

    摘要: A data processing system stack initializes a first mbuf chain limit to a pre-set level. It receives at least one packet. The system receives at least one packet. The system returns an mbuf data structure in response to receiving at least one packet from an IP address. The system measures a health of the network connection to determine whether the network connection satisfies a first health criterion. The system reduces the mbuf chain limit to a second mbuf chain limit, responsive to the health of the network connection not satisfying the first health criterion. The system measures the health of the network connection to determine whether the network connection meets a second health criterion.

    摘要: An information handling system (IHS) includes a network adapter having a hardware address store that stores multicast addresses and a device driver that stores multicast addresses in a software address store. When there is no more storage space available in the hardware address store for multicast addresses, the device driver stores multicast addresses in the software address store. When the IHS receives a multicast information packet, the network adapter searches the hardware address store for a multicast address corresponding to that multicast information packet. If the search of the hardware address store does not find that multicast address, then the device driver searches the software address store for that multicast address. The IHS may prioritize the multicast addresses in the hardware address store and the software address store on a most frequently used basis, a most recently used basis or a most popular basis. For example, the hardware address store may store addresses that are more frequently used than those in the software address store.

    摘要: Disclosed is a computer implemented method, computer program product, and apparatus to enqueue one or more packets in a device driver for an I/O adapter. A device driver receives, by a processor executing the device driver, a reference to a list of transmit packets. The device driver may then atomically fetch and set a transmit active flag, wherein atomically setting comprises determining a former status of the transmit active flag. Responsive to a determination that a former status of the transmit active flag is different than a current status of the transmit active flag, the device driver atomically removes, by a processor executing the device driver, any packets referenced by a host machine transmit queue reference. The device driver pre-pends transmit packets referenced by the host machine transmit queue reference to the list of transmit packets to form an augmented list of transmit packets. The device driver builds a work request based on the augmented list of transmit packets. The device driver notifies the I/O adapter of the work request. The device driver atomically resets the transmit active flag.
