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： 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.
摘要翻译：在链路聚合配置中，可以将数据分组复制到第一NIC的缓冲空间中。负载均衡技术可以确定分组应该由第二NIC发送。数据包存在于第二个NIC无法访问的内存中。将数据包复制到第二个NIC可访问的存储器中，或者将该数据包的存储位置注册到NIC。如果将数据包从第一个缓冲区复制到第二个缓冲区，则会产生复制损失。如果第一个缓冲空间内的位置与第二个NIC进行了注册，就会产生注册损失。可以在链路聚合配置中实现功能，以注册在互连NIC之间共享的缓冲区空间。在互连NIC之间共享缓冲区空间允许任何一个NIC访问共享缓冲区空间内的数据，而不会造成惩罚。

摘要： A method for selective link aggregation in a virtualized data processing environment is provided in the illustrative embodiments. A data packet is received at a switch. An identifier associated with the data packet is determined. The identifier corresponds to a logical partition in a logical partitioned data processing system. A lookup is performed in a data structure to determine a set of ports associated with the identifier. The set of ports is retrieved from the data structure. A port is selected from the set of ports and the data packet is transmitted from the port to the logical partition.

摘要： Various systems, processes, and products may be used to filter multicast messages in virtual environments. In particular implementations, a system, process, and product for filtering multicast messages in virtual environments may include the ability to determine whether a multicast message has been received, examine a local filtering store for a match for the destination address of the multicast message, and send the message to a number of virtual machines if a match for the address is found. The system, process, and product may also include the ability to analyze a filtering store of at least one of the virtual machines for a match for the address if a match is not found in the local filtering store and send the message to a number of the virtual machines if a match for the address is found in a filtering store of one of the virtual machines.

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.
摘要翻译：信息处理系统（IHS）包括具有存储多播地址的硬件地址存储器的网络适配器和在多个地址存储器中存储组播地址的设备驱动程序。当硬件地址存储区中没有可用的多播存储空间时，设备驱动程序将多播地址存储在软件地址存储区中。当IHS接收到组播信息包时，网络适配器在硬件地址存储中搜索与该组播信息包相对应的组播地址。如果对硬件地址存储的搜索没有找到多播地址，则设备驱动程序在软件地址存储中搜索该多播地址。 IHS可以在最经常使用的基础上，最近使用的基础或最受欢迎的基础来优先考虑硬件地址存储器中的多播地址和软件地址存储。例如，硬件地址存储可以存储比软件地址存储器中更频繁使用的地址。

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.
