Abstract: A method and technique for updating firmware on a multi-protocol network adapter includes reading parameter values for a firmware update of a multi-protocol network adapter that specify classes of behavior for conducting the firmware update of the multi-protocol network adapter. An update tool determines a reset type defining a type of reset needed to activate the firmware update on the network adapter based on the parameter values, sends a message to the network adapter indicating that a firmware update process is beginning, sends a write request to the network adapter to write the firmware update to select communication protocol functions, and sends a reset request to select communication protocol functions to activate the firmware update using the reset type according to the parameter values.

Abstract: 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, responsive to receiving a multicast message including a destination address, examine a local filtering store of the network adapter for a multicast filtering address matching the destination address. The message is sent to respective virtual machines if the destination address matches the multicast filtering address found in the local filtering store for the respective virtual machines. Responsive to determining that the destination address does not match any multicast filtering address found in the local filtering store, a determination is made whether the local filtering store is full and, if so, the multicast message is dropped.

Abstract: An approach is provided that collects data from a multi-function adapter that is used by multiple functions. In the approach, a master function is dynamically selected from the group of functions. The approach further allows the master function to perform a disruptive adapter data collection while inhibiting performance of disruptive adapter data collection processes by the other (non-master) functions.

Abstract: Mechanisms are provided for generating a system dump data structure based on device state data. A system dump operation is initialized in a data processing system and a device dump is requested by a dump manager from a device coupled to the data processing system. A collection scope data structure and disruption vector corresponding to the device are retrieved. The collection scope data structure specifies a set of one or more functions in the device for which to collect state data. The disruption vector specifies, for each of the one or more functions, a corresponding level of disruption that will be caused by the device dump. The device dump data is collected from the device in accordance with the collection scope data structure and the disruption vector and the system dump data structure is generated based on the collected device dump data.
