如果 checksum 通过了,数据是 UDP 或者 TCP 数据,skb 就会被标记成CHECKSUM_UNNECESSARY。 构建的 skb 经napi_gro_receive()进入协议栈。 更新处理过的包的统计信息。 循环直至处理的包数量达到 budget。 循环结束的时候,这个函数设置收包的数量和字节数统计信息。 5. 总结 本文主要介绍Linux网络设备子系统的数据处...
支持FCoE(Fibre Channel over Ethernet)的最大传输单元(MTU)相关功能,可能与存储网络在以太网上的传输相关。 ethtool.feature-gro 通用接收卸载(Generic Receive Offload),通过将多个小数据包合并成一个大的数据包来减少 CPU 处理的开销。 ethtool.feature-gso 通用分段卸载(Generic Segmentation Offload),将大的数据...
