摘要： A technique for accessing features of a hardware adapter includes reading a first key from a hardware adapter and attempting to decrypt the first key with a second key. In response to the second key successfully decrypting the first key: encrypted code from the hardware adapter is read; the encrypted code is decrypted with the decrypted first key to generate unencrypted code; and a default code in an executable flash sector of the hardware adapter is over-written with the unencrypted code. In this case, the unencrypted code facilitates access to at least one feature of the hardware adapter that is customer specific. In response to the second key not successfully decrypting the first key, the default code in the executable flash sector of the hardware adapter is not over-written. In this case, the default code facilitates access to one or more features that are not customer specific.

摘要： Various systems, processes, and products may be used to manage the transmission and reception of messages. In particular implementations, a system, process, and product for managing message transmission and reception may include the ability to receive a plurality of messages to be transmitted over a communication network, wherein some of the messages have a higher priority and some of the messages have a lower priority, and enqueue descriptors for the messages in a direct memory access queue. The system, process, and product may also include the ability to determine whether an overrun of the queue has occurred, analyze the queue if an overrun has occurred to determine if lower priority messages are associated with any of the descriptors in the queue, and replace, if descriptors for lower priority messages are in the queue, the descriptors for the lower priority messages with descriptors for higher priority messages.

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.

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： A mechanism is provided for providing resource affinity for multi-queue network adapters via dynamic reconfiguration. A device driver allocates an initial queue pair within a memory. The device driver determines whether workload of the data processing system has risen above a predetermined high threshold. Responsive to the workload rising above the predetermined high threshold, the device driver allocates and initializes an additional queue pair in the memory. The device driver programs a receive side scaling (RSS) mechanism in a network adapter to allow for dynamic insertion of an additional processing engine associated with the additional queue pair. The device driver enables transmit tuple hashing to the additional queue pair.

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.
