在某些情况下,确实可能无法更改tcp-segmentation-offload(TSO)的设置。 这通常是由以下几个原因造成的: 硬件限制: 某些网卡可能不支持TSO功能,或者其驱动不支持通过ethtool等工具进行配置。 如果网卡或驱动不支持,尝试更改TSO设置时可能会遇到错误或无效的情况。 系统配置: 系统可能默认禁用了对某些网络参数的修改,或者...
Abbreviated as TSO, TCP segmentation offload is used to reduce the CPU overhead of TCP/IP on fast networks. TSO breaks down large groups of data sent over a network into smaller segments that pass through all the network elements between the source and destination. This type of offload ...
这三者缺一不可,而出现"Cannot set device tcp segmentation offload settings: Invalid argument"的原因 就是没有事先启用scatter-gather选项。

Poor performance for VMs on Overlay Logical Switch when TCP Segmentation Offload (TSO) is enabled on the VMs. When the same VMs are VLAN Logical Switch or DVS/VSS portgroups, no performance issue are seen. The following Network cards are used:QLogic Corp. QLogic FastLinQ QL41xxx 1/10/25 ...
Systems, apparatusses, and methods are disclosed for transmission control protocol (TCP) segmentation offload (TSO). A hardware TSO engine is capable of handling segmentation of data packets and consequent header field mutation of hundreds of flows simultaneously. The TSO engine generates data pointers...
Thus, the higher layer processing specifies a very large datagram, which is automatically segmented at the network interface layer, instead of at the TCP layer.US5937169 * Oct 29, 1997 Aug 10, 1999 3Com Corporation Offload of TCP segmentation to a smart adapter...
The plurality of packets include respective headers, such as TCP/IP headers, based on the header template, and include respective segments of the data payload. The network interface (15) supports packets having a pre-specified length, and the data payload (100) is greater than the pre-...
