46. ICE PF enable Protocol agnostic flow offloading in RSS¶

46.1. Description¶

ICE PF enable protocol agnostic flow offloading in rss, that means we can use raw packet filter instead of naming filter(legacy flow offloading). As the raw packet filter using spec and mask to describr pattern and input set, the protocol agnostic flow offloading is more flexible and customizable compared with legacy flow offloading. To reduce redundancy, we don’t check all the patterns and input set which is covered by naming filter test cases. this plan only cover below test hints to check the feasibility of protocol agnostic flow offloading:

try RSS with regular 5 tuples for any UDP or TCP packet
try RSS with VXLAN inner IP match (make sure VXLAN tunnel port has been configured either by DCF or swtichdev)
try RSS with GTPU inner IP match
try RSS with GTPU outer IP match
try RSS with un-word-aligned key

And all the rules are created by packageviewer(ICE parser emulator). The first string of numbers in the rule represents the matched packet’s raw pattern spec, the second string represents the mask, using ‘F’ to mask the inputset. Pls get the tool from Intel DPDK team. ..note:: there will be conflict between raw packet filter and naming filter, so need to disable default rss when testing raw packet filter.

46.2. Prerequisites¶

46.2.1. Hardware¶

Supportted NICs: Intel® Ethernet 800 Series: E810-CQDA2/E810-2CQDA2/E810-XXVDA4 etc.

46.2.2. Software¶

DPDK: http://dpdk.org/git/dpdk Scapy: http://www.secdev.org/projects/scapy/

46.2.3. General Set Up¶

Compile DPDK:

# CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib --default-library=static <dpdk build dir>
# ninja -C <dpdk build dir> -j 110

Get the pci device id and interface of DUT and tester. For example, 0000:18:00.0 and 0000:18:00.1 is pci device id, ens785f0 and ens785f1 is interface:

<dpdk dir># ./usertools/dpdk-devbind.py -s

0000:18:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci
0000:18:00.1 'Device 159b' if=ens785f1 drv=ice unused=vfio-pci

Bind the DUT port to dpdk:

<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port pci device id>

Launch the userland testpmd application on DUT as follows and

<dpdk build dir>/app/dpdk-testpmd <EAL options> -- -i --rxq=<queue number> --txq=<queue number>
testpmd> set fwd rxonly
testpmd> set verbose 1
testpmd> rx_vxlan_port add 4789 0
testpmd> start

..note:

For <EAL options>, you can use "-c 0xf -n 1", you can also refer to testpmd doc for other setings.

Import layers when start scapy:

>>> import sys
>>> from scapy.contrib.gtp import *

46.3. Test Case¶

46.3.1. common steps¶

toeplitz cases 1. validate rules. 2. create rules and list rules. 3. send a basic hit pattern packet,record the hash value, check the packet distributed to queue by rss 4. send hit pattern packets with changed input set in the rule, check the received packets have different hash value with basic packet, check all the packets are distributed to queues by rss 5. send hit pattern packets with changed input set not in the rule, check the received packet have same hash value with the basic packet, check all the packets are distributed to queues by rss

..note::: if there is not this type packet in the case, omit this step.

destroy the rule and list rule. check the flow list has no rule.

symmetric cases 1. validate rules. 2. create rules and list rules. 3. send a basic hit pattern packet,record the hash value. 4. send a hit pattern packet with switched value of input set in the rule, check the received packets have same hash value, check both the packets are distributed to queues by rss 5. destroy the rule and list rule. 6. send the packet in step 4, check the received packet has different hash value with which in step 3(including the case has no hash value).
