因此,当rss_hf的值为0x7ef8(二进制为0111 1110 11111000)时,表示开启了所有可支持的 RSS 字段。而当该值为0x1(二进制为0000 0000 ...0001)时,则只启用了 IPv4 源地址,这显然是不合法的。 因此,当 DPDK 程序运行时出现 “Ethdev port_id=0 invalid rss_hf: 0x1, valid value: 0x7ef8” 这样的错误...

Ethtool is a standard Linux utility for controlling network drivers and hardware, particularly for wired Ethernet devices. It can be used to: Get identification and diagnostic information Get extended device statistics Control speed, duplex, auto-negotiation and flow control for Ethernet devices ...
This also resets the RSS table to its default distribution, which is uniform across the cores on the NUMA (non-uniform memory access) node that is closer to the NIC. For ConnectX®-4 cards, use ethtool -L eth<x> combined <N> to set both RX and TX channels. ...

This post shows how to steer PTP traffic to single RX ring via ethtool commands. PTP traffic uses UDP ports 320 and 319, As a result of RSS (Receive Side Steering) PTP traffic coming to UDP ports 319 and 320, it may arrive to the user space applicationout of order. In order to pr...
