Abstract: Traffic between a first device and a second device across a plurality of communication lanes of a communication link is stalled. A first device side of the communication lane is powered-down on at least one of the plurality of communication lanes to deactivate the at least one communication lane. A power-down request is sent from the first device to the second device to power-down a second device-side of the at least one communication lane. Traffic between the first device and the second device is restarted over the active communication lanes.

Abstract translation: 跨越通信链路的多个通信通道的第一设备和第二设备之间的通信被停止。 通信通道的第一设备侧在多个通信通道中的至少一个通电通道上断电，以停用至少一个通信通道。 从第一设备向第二设备发送断电请求以将所述至少一个通信通道的第二设备侧断电。 第一设备和第二设备之间的业务通过主动通信线路重启。

Abstract: This disclosure describes techniques for a network interface controller (NIC) to communicate over a network according to a specified transmission communication protocol. The NIC receives, from a host processor, an indication of a data unit and an indication of a header template. The NIC generates, independent of the specified transmission communication protocol, metadata for transmitting a segment of the data unit over a network. The NIC generates, at last partly using the metadata, header fields that comply with the specified transmission communication protocol. The NIC processes the header template and the header fields to generate a packet header, and the NIC transmits, over the network, a packet including the packet header and the segment of the data unit.
