Key model elements are: > - apply matches to both outer and inner packet headers > during entire offload procedure; > - restore outer header of partially offloaded packet; > - model is implemented as a set of helper functions. > > Implementation details: > > * Create application tunnel: > flow tunnel create <port> type <tunnel type> > On success, the command creates application tunnel object and returns > the tunnel descriptor. Tunnel descriptor is used in subsequent flow > creation commands to reference the tunnel. > > * Create tunnel steering flow rule: > tunnel_set <tunnel descriptor> parameter used with steering rule > template. > > * Create tunnel matching flow rule: > tunnel_match <tunnel descriptor> used with matching rule template. > > * If tunnel steering rule was offloaded, outer header of a partially > offloaded packet is restored after miss. > > Example: > test packet= > <Ether dst=24:8a:07:8d:ae:d6 src=50:6b:4b:cc:fc:e2 type=IPv4 | > <IP version=4 ihl=5 proto=udp src=1.1.1.1 dst=1.1.1.10 | > <UDP sport=4789 dport=4789 len=58 chksum=0x7f7b | > <VXLAN NextProtocol=Ethernet vni=0x0 | > <Ether dst=24:aa:aa:aa:aa:d6 src=50:bb:bb:bb:bb:e2 type=IPv4 | > <IP version=4 ihl=5 proto=icmp src=2.2.2.2 dst=2.2.2.200 | > <ICMP type=echo-request code=0 chksum=0xf7ff id=0x0 seq=0x0 |>>>>>>> > >>> len(packet) > 92 > > testpmd> flow flush 0 > testpmd> port 0/queue 0: received 1 packets > src=50:6B:4B:CC:FC:E2 - dst=24:8A:07:8D:AE:D6 - type=0x0800 - > length=92 > > testpmd> flow tunnel 0 type vxlan > port 0: flow tunnel #1 type vxlan > testpmd> flow create 0 ingress group 0 tunnel_set 1 > pattern eth /ipv4 / udp dst is 4789 / vxlan / end > actions jump group 0 / end > Flow rule #0 created > testpmd> port 0/queue 0: received 1 packets > tunnel restore info: - vxlan tunnel - outer header present # <-- > src=50:6B:4B:CC:FC:E2 - dst=24:8A:07:8D:AE:D6 - type=0x0800 - > length=92 > > testpmd> flow create 0 ingress group 0 tunnel_match 1 > pattern eth / ipv4 / udp dst is 4789 / vxlan / eth / ipv4 / > end > actions set_mac_dst mac_addr 02:CA:FE:CA:FA:80 / > queue index 0 / end > Flow rule #1 created > testpmd> port 0/queue 0: received 1 packets > src=50:BB:BB:BB:BB:E2 - dst=02:CA:FE:CA:FA:80 - type=0x0800 - > length=42 > > * Destroy flow tunnel > flow tunnel destroy <port> id <tunnel id> > > * Show existing flow tunnels > flow tunnel list <port> > > Signed-off-by: Gregory Etelson <getel...@nvidia.com> > --- > v2: > * introduce testpmd support for tunnel offload API > > v3: > * update flow tunnel commands > ---
