Abstract: A method and system for substantially avoiding loss of data and enabling continuing connection to the application during an MTU size changing operation in an active network computing device. Logic is added to the device driver, which logic provides several enhancements to the MTU size changing operation/process. Among these enhancements are: (1) logic for temporarily pausing the data coming in from the linked partner while changing the MTU size; (2) logic for returning a “device busy” status to higher-protocol transmit requests during the MTU size changing process. This second logic prevents the application from issuing new requests until the busy signal is removed; and (3) logic for enabling resumption of both flows when the MTU size change is completed. With this new logic, the device driver/adapter does not have any transmit and receive packets to process for a short period of time, while the MTU size change is ongoing.

Abstract translation: 一种用于在活动网络计算设备中在MTU大小改变操作期间基本上避免数据丢失并使得能够持续连接到应用的方法和系统。 逻辑被添加到设备驱动程序，该逻辑提供了对MTU大小改变操作/过程的几个增强。 这些增强功能包括：（1）在改变MTU大小的同时临时暂停从链接伙伴进来的数据的逻辑; （2）在MTU大小改变过程中将“设备忙”状态返回到更高协议传输请求的逻辑。 该第二逻辑防止应用程序发出新的请求，直到忙信号被移除; 和（3）当MTU大小改变完成时能够恢复两个流的逻辑。 使用这种新的逻辑，设备驱动程序/适配器没有任何发送和接收数据包在短时间内处理，而MTU大小更改正在进行。

Abstract: A method, medium and implementing processing system are provided in which the Operating System (OS) driver is divided into two parts, viz. an upper level OS driver and a lower level OS driver. The lower level OS driver sets up the adapter hardware and any adapter hardware work-around. The upper level OS driver is interfaced to the OS communication stack and each can be compiled separately. The upper OS driver is compiled and shipped with the OS to make sure it is compatible with the OS communication stack. The lower OS driver, in an exemplary embodiment, is compiled and stored in an adapter flash memory. The OS dynamically combines the upper and lower OS drivers together during the load time.

Abstract: Methods and arrangements to monitor communication components such as a network adapters for activity, and identify components that have lower than normal levels of activity are provided. An identified communication component can become suspect component and a candidate for further testing, including different forms of interrogation. Process for interrogating candidates can include generating and sending test packets having the media access control (MAC) address of the candidate to the candidate and if activity is not detected subsequent to the interrogation, the candidate can be flagged as a failed component. Correspondingly, the component can be deactivated and removed from service. In a further embodiment, a backup component can be activated and assume the role previously held by the failed component.

Abstract: A plurality of data packets encoded according to a first protocol are received which encapsulate data encoded according to a second protocol. A first source address is extracted from the packets according to the first protocol, it is determined whether or not the first source address is a substantial duplicate of a known assigned address. If it is a duplicate, a second source address is extracted from the encapsulated data according to the second protocol, and the first source address and said second source address are provided in an enhanced error log so that a system administrator may correct the duplicate assigned address. Enhanced embodiments of the invention included analysis of data encapsulated by a third, fourth and subsequent protocols, and automatic determination of each protocol encoding format.

Abstract: A method, apparatus, and computer instructions for transferring data from a memory to a network adapter in a data processing system. The frame size for a transfer of the data from the memory to the network adapter is identified. If the frame size is divisible by a cache line size without a remainder, a valid data length is set equal to the length field. However, if the frame size divided by the cache line size results in a remainder, the length field is set to align the data with the cache line size. The data transfer is then initiated using these fields.
