DDP PPPoE Profile

Intel® Ethernet Controller X710/XXV710/XL710 Adapters Dynamic Device Personalization PPPoE Package 下载 DDP PPPoE Profile 解压.

启动 testpmd 加载 DDP Profile:

映射 pctype 15: PPPoE IPV4 到 DPDK flow type 15:

testpmd> port config 0 pctype mapping update 15 15
testpmd> port start 0

pctype: 15  ->  flowtype: 15

  • port config 0 pctype mapping update 15 15 调用 rte_pmd_i40e_flow_type_mapping_update() 映射 pctype 22 到 DPDK flow type 15 ．

  • port config all rss 22 对 flowtype 15 启用 RSS．

scapy 发送测试PPPOE IPv4报文:

from scapy.all import *pkt=Ether(dst="90:e2:ba:0a:73:0c")/PPPoE(sessionid=0x7)/PPP(proto=0x21)/IP(src="1.1.1.1",dst="2.2.2.2")/UDP(sport=4000,dport=8000)/Raw('x' * 20)
