Public bug reported:
How to reproduce:
Start testpmd using the following command:
testpmd -n 4 -w 00:06.0,mprq_en=0,rx_vec_en=0,tx_vec_en=0 -w
00:07.0,mprq_en=0,rx_vec_en=0,tx_vec_en=0 -- --burst=64 --mbcache=512 -i
--nb-cores=11 --txd=1024 --rxd=1024 --disable-hw-vlan-strip --forward-
mode=rxonly
testpmd> port stop all
Then add the following rules:
flow create 0 ingress pattern eth dst spec ec:0d:9a:46:a0:04 dst mask
FF:FF:FF:FF:FF:FF src spec 00:16:3e:3f:74:39 src prefix 48 / vlan vid spec
1578 vid mask 0xff0 / ipv6 src spec ::7eb1 src mask
ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff dst spec ::7eb1 dst mask
0000:0000:0000:0000:0000:0000:0000:0000 proto is 47 tc spec 0 tc mask 0x0 /
end actions rss queues 0 end / end
flow create 0 ingress pattern eth dst spec ec:0d:9a:46:a0:04 dst mask
FF:FF:FF:FF:FF:00 src spec 00:16:3e:6b:52:3e src prefix 0 / vlan vid spec
1062 vid prefix 8 / ipv6 dst spec ::d739 dst prefix 128 proto spec 47
proto prefix 0 flow is 0 / end actions rss queues 0 end / end
flow create 0 ingress pattern eth src spec 00:16:3e:75:1a:e3 src mask
FF:FF:FF:FF:FF:00 / ipv4 dst spec 234.191.135.109 dst mask 0.0.0.0 proto

end / mark id 36 / end
flow create 0 ingress pattern end actions rss queues 0 end / end
flow create 0 ingress pattern eth dst spec ec:0d:9a:46:a0:04 dst prefix 32
src is 00:16:3e:61:7f:dd / ipv4 src spec 195.14.171.117 src mask
255.255.255.255 proto spec 17 proto mask 0x0 / udp src spec 49934 src mask
0xffff / vxlan vni spec 8497260 vni mask 0xffffff / end actions rss queues
0 end / mark id 62 / end
testpmd> port start all
Then restart the ports:
testpmd> port stop all
testpmd> port start all
testpmd>start
Then send the following packet via scapy:
packet = Ether(src='00:16:3e:3f:74:39', dst='ec:0d:9a:46:a0:04',
type=33024)/Dot1Q(vlan=1573, type=34525, id=0, prio=0)/IPv6(nh=47,
src='::7eb1', dst='9e8e:6edc:62cf:7058:b032:7fe2:4001:a95b', version=6, hlim=1,
plen=1442, fl=0, tc=1
)/GRE(routing_present=1, chksum_present=1, version=6, proto=17990,
offset=17990, strict_route_source=0, seqnum_present=0, key_present=0,
recursion_control=6, flags=8, key=None, chksum=55897, seqence_number=None)
packet.add_payload('F' * (1496 - len(packet) - 4 ))
sendp(packet, iface = 'ens6', count = 1)
Real result testpmd didn't received any traffic
