dut: 10.240.176.192
tester: 10.240.176.191
X552/X557-AT 10g*2
Test steps:
Bind pf to igb_uio:
./usertools/dpdk-devbind.py -b igb_uio 03:00.0
add two vfs on dpdk pf, then bind the vfs to vfio-pci:
echo 2 >/sys/bus/pci/devices/0000:03:00.0/max_vfs
./usertools/dpdk-devbind.py -b vfio-pci 03:10.0 03:10.2
Start testpmd:
./x86_64-native-linuxapp-gcc/app/testpmd -c 1f -n 4 -m 1024 -w 03:00.0
--file-prefix=pf - -i --rxq=4 --txq=4
testpmd> set fwd rxonly
testpmd> set verbose 1
testpmd> start
testpmd> port config 0 l2-tunnel E-tag enable
testpmd> E-tag set forwarding on port 0
./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf0 -n 4 -w 03:10.0
--file-prefix=vf0 -m 1024 - -i --rxq=4 --txq=4 --disable-rss
testpmd> set fwd rxonly
testpmd> set verbose 1
testpmd> start
./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf00 -n 4 -w 03:10.2
--file-prefix=vf1 -m 1024 - -i --rxq=4 --txq=4 --disable-rss
testpmd> set fwd rxonly
testpmd> set verbose 1
testpmd> start
1. create filter rules,
testpmd> flow create 0 ingress pattern e_tag grp_ecid_b is 0x1309 / end actions
vf id 0 / end
Flow rule #0 created
testpmd> flow create 0 ingress pattern e_tag grp_ecid_b is 0x1308 / end actions
vf id 1 / end
Flow rule #1 created
testpmd> flow create 0 ingress pattern e_tag grp_ecid_b is 0x1307 / end actions
pf / end
Flow rule #2 created
2. send packets:
pkt1 = Ether(dst="00:11:22:33:44:55")/Dot1BR(GRP=0x1, ECIDbase=0x309)/Raw('x' *
20)
pkt2 = Ether(dst="00:11:22:33:44:55")/Dot1BR(GRP=0x1, ECIDbase=0x308)/Raw('x' *
20)
pkt3 = Ether(dst="00:11:22:33:44:55")/Dot1BR(GRP=0x1, ECIDbase=0x307)/Raw('x' *
20)
pkt4 = Ether(dst="00:11:22:33:44:55")/Dot1BR(GRP=0x2, ECIDbase=0x309)/Raw('x' *
20)
verify pkt1 to vf0 queue0, pkt2 to vf1 queue0, pkt3 to pf queue 0, pkt4 can't
received by pf and vfs.
