摘要： Provided are a method, system, and program for managing transmit throughput for a network controller. In one embodiment, transmit requests from an application may be posted by the device driver to the network controller of the network adapter in a pipeline of transmit requests without waiting for an acknowledgment of the transfer of the accompanying transmit data to the network controller. In another aspect, a device driver monitors the available buffer space of a network controller buffer to ensure that the network controller has sufficient available buffer space before posting the next transmit request to the network controller. In accordance with yet another aspect, the device driver can copy transmit data from an application buffer to a driver buffer if the size of the transmit data of a particular transmit request is below a programmable threshold. If so, the device driver can notify the application to permit the application buffer to be released.
摘要翻译：提供了一种用于管理网络控制器的发送吞吐量的方法，系统和程序。在一个实施例中，来自应用的发送请求可以由设备驱动程序以发送请求的流水线发布到网络适配器的网络控制器，而不必等待对所述网络控制器的所附送的传输数据的传送的确认。在另一方面，设备驱动程序监视网络控制器缓冲器的可用缓冲区空间，以确保网络控制器在向网络控制器发布下一个发送请求之前具有足够的可用缓冲区空间。根据另一方面，如果特定发送请求的发送数据的大小低于可编程阈值，则设备驱动程序可以将发送数据从应用缓冲器复制到驱动器缓冲器。如果是这样，设备驱动程序可以通知应用程序以允许释放应用程序缓冲区。

摘要： According to some embodiments, it may be determined, at a first processing element of a device with a plurality of processing elements, that first data is to be transmitted in association with a first network connection. A first entry associated with the first data may then be stored into a first of a plurality of transmit queues. It may subsequently be determined, at a second processing element of the device, that second data is to be transmitted in association with the first network connection. A second entry associated with the second data may then be stored into a second of the plurality of transmit queues.

A processing core of the first device may wake-up the second device after generating a first data unit. The second device may generate steering values after retrieving a first data unit directly from the cache of the first device. The second device may populate a flow table with a plurality of entries using the steering values. The second device may receive a packet over a network and store the packet directly into the cache of the first device using a first steering value. The second device may direct an interrupt signal to the processing core of the first device using a second steering value.
