WebOtherwise GRO will be done. Generic Receive Offload (GRO) is available throughout all kernels. Hardware VLAN Striping Offload (rxvlan): When enabled received VLAN traffic will be stripped from the VLAN tag by the hardware.

WebThis module provides a procedural interface to the basic operations provided by the Linux SIOCETHTOOL ioctl. The more complex operations that involve getting or setting whole structures at a time are implemented in OO fashion by packages under this namespace. WebRight. So unlike TSO, GRO is not a transparent, generally applicable performance improvement. It's more like a form of graceful degradation, helping a server to sustain overall throughput when it is already swamped in TCP traffic. Thanks for your clarification.
