[dpdk-users] using rte_flow via tespmd with Intel X552

[dpdk-users] using rte_flow via tespmd with Intel X552

[Tetsuro Nakamura]

Hi All,

I'm now trying to use simple L2 function with "Generic Flow API (rte_flow)"
using testpmd in dpdk-17.02,
but it doesn't work with the error below.

-----------
$sudo ./dpdk-17.02/x86_64-native-linuxapp-gcc/app/testpmd -l 0-3 -n 4 -- -i
--portmask=0x3 --nb-cores=2

testpmd> flow validate 0 ingress pattern eth / eth dst is a0:36:9f:78:30:26
/ end actions drop / end
Caught error type 9 (specific pattern item): cause: 0x7ffd225adc88, Not
supported by L2 tunnel filter
testpmd> flow validate 0 ingress pattern eth / eth dst is a0:36:9f:78:30:26
/ end actions queue index 0 / end
Caught error type 9 (specific pattern item): cause: 0x7ffd225adc88, Not
supported by L2 tunnel filter
-----------

I tried several other flows and got the same error.
I'm using Intel X552 NIC. The firmware-version is 0x800003e7.

-----------
$ sudo ethtool -i rename6
driver: ixgbe
version: 5.0.4
firmware-version: 0x800003e7
expansion-rom-version:
bus-info: 0000:03:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no
-----------

My question is,
am I missing some additional settings to do ?
Should I use another firmware version ?
# DPDK 17.02 official release note says the tested firmware version was
0x800001cf.
# My version, 0x800003e7 is newer, isn't it?

I don't think the NIC does't support such simple L2 functions.
But if it doesn't, are there any documents that tell us which NIC supports
which flow rules in rte_flow?
Could you tell me what flows I can try with Intel X552 NIC?

Thank you and best regards,

Tetsuro Nakamura, NTT

I'm not familiar with ixgbe but this issue reminds me of this thread [1],
particularly the following comment:

 "the rte_flow_error returned was not very useful for it does return the
 error of the last tried filter-type (L2 tunnel in ixgbe), and not the error
 of the filter-type that my setup should use (flow director)"

CC'ing Wenzhuo, I think this issue is present in 17.02, has it been fixed
since?

[TETSURO NAKAMURA]

Hi Wei,
(Cc'ing Wenzhuo)

According the e-mail thread [1] below in April,
you have a document about command format when creating flow on ixgbe NICs.

Could you just upload that document to community or
could you share it via an e-mail with me ??

Hi All,

I understand. Then I will wait for the documentation.
Anyway, I appreciate your kind response !

Dear Adrien and Wenzhuo,

Thank you very much for your kind reply.
I tried flow_director_filter API directly using testpmd with the same environment.
So let me add more information.

- Using pktgen-3.0.13, I prepared 2 flows whose dst-Macs are  0c:c4:7a:cf:66:11 and 0c:c4:7a:cf:66:12 respectively.
```
Pktgen> set 0 seqCnt 2　
Pktgen> seq 0 0 0c:c4:7a:cf:66:11 0c:c4:7a:cf:66:01 192.168.1.1 192.168.0.1/24<http://192.168.0.1/24> 1234 5678 ipv4 udp 1 64
Pktgen> seq 0 0 0c:c4:7a:cf:66:12 0c:c4:7a:cf:66:02 192.168.1.1 192.168.0.1/24<http://192.168.0.1/24> 1234 5678 ipv4 udp 1 64
Pktgen> start 0
```

- Then I started testpmd with options of "--rxq=2 --txq=2" and "--pkt-filter-mode=perfect-mac-vlan".
- No error had occurred when configuring flow_director_filter.
- When started, all packets were received in Pktgen.
```
$sudo ./dpdk-17.04/x86_64-native-linuxapp-gcc/app/testpmd -l 0-4 -n 4 -- -i --portmask=0x3 --nb-cores=4 --rxq=2 --txq=2 --pkt-filter-mode=perfect-mac-vlan

testpmd> flow_director_filter 0 mode MAC-VLAN add mac 0c:c4:7a:cf:66:11 vlan 1 flexbytes (0x80,0x00) fwd queue 0 fd_id 1
testpmd> flow_director_filter 0 mode MAC-VLAN add mac 0c:c4:7a:cf:66:12 vlan 1 flexbytes (0x80,0x00) fwd queue 1 fd_id 2
testpmd> start
```

- When queue 0 was stopped, no packet was received in Pktgen.
```
testpmd> stop
testpmd> port 0 rxq 0 stop
testpmd> start
```

- When queue 1 was stopped, all packets were received in Pktgen.
```
testpmd> stop
testpmd> port 0 rxq 0 start
testpmd> port 0 rxq 1 stop
testpmd> start
```

- which (I guess) mean the flow is not supported as you said.
- The mac argument in flow_director_filter is dst-Mac, right?
[Wenzhuo] Yes. It’s dst-mac. It’s the benefit of generic flow API. Using generic API  users do know what fields the input are. But the original one, users have to check the comments and docs ☺

About the previous discussion, Wei has sent the patch to remove the tpid in ixgbe. But no improvement of error message yet as I know.

I think this flow is not supported. Generic flow API is flexible enough, but not every flow can be supported. The flow is supported or not has nothing to do with if it's simple. It's limited to HW capability. Wei, do you have some doc to shared or even has uploaded to the community? Thanks.

We have a document about command format when creating flow,  but has not been publicly upload to community.

I will add a new chapter for this in doc\guides\nics\ixgbe.rst later, which is about command format when creating flow.

A specific patch will be send to community later.

Dear Adrien and Wenzhuo,

Thank you very much for your kind reply.
I tried flow_director_filter API directly using testpmd with the same environment.
So let me add more information.

- Using pktgen-3.0.13, I prepared 2 flows whose dst-Macs are  0c:c4:7a:cf:66:11 and 0c:c4:7a:cf:66:12 respectively.
```
Pktgen> set 0 seqCnt 2　
Pktgen> seq 0 0 0c:c4:7a:cf:66:11 0c:c4:7a:cf:66:01 192.168.1.1 192.168.0.1/24<http://192.168.0.1/24> 1234 5678 ipv4 udp 1 64
Pktgen> seq 0 0 0c:c4:7a:cf:66:12 0c:c4:7a:cf:66:02 192.168.1.1 192.168.0.1/24<http://192.168.0.1/24> 1234 5678 ipv4 udp 1 64
Pktgen> start 0
```

- Then I started testpmd with options of "--rxq=2 --txq=2" and "--pkt-filter-mode=perfect-mac-vlan".
- No error had occurred when configuring flow_director_filter.
- When started, all packets were received in Pktgen.
```
$sudo ./dpdk-17.04/x86_64-native-linuxapp-gcc/app/testpmd -l 0-4 -n 4 -- -i --portmask=0x3 --nb-cores=4 --rxq=2 --txq=2 --pkt-filter-mode=perfect-mac-vlan

testpmd> flow_director_filter 0 mode MAC-VLAN add mac 0c:c4:7a:cf:66:11 vlan 1 flexbytes (0x80,0x00) fwd queue 0 fd_id 1
testpmd> flow_director_filter 0 mode MAC-VLAN add mac 0c:c4:7a:cf:66:12 vlan 1 flexbytes (0x80,0x00) fwd queue 1 fd_id 2
testpmd> start
```

- When queue 0 was stopped, no packet was received in Pktgen.
```
testpmd> stop
testpmd> port 0 rxq 0 stop
testpmd> start
```

- When queue 1 was stopped, all packets were received in Pktgen.
```
testpmd> stop
testpmd> port 0 rxq 0 start
testpmd> port 0 rxq 1 stop
testpmd> start
```

- which (I guess) mean the flow is not supported as you said.
- The mac argument in flow_director_filter is dst-Mac, right?
[Wenzhuo] Yes. It’s dst-mac. It’s the benefit of generic flow API. Using generic API  users do know what fields the input are. But the original one, users have to check the comments and docs ☺

About the previous discussion, Wei has sent the patch to remove the tpid in ixgbe. But no improvement of error message yet as I know.

I think this flow is not supported. Generic flow API is flexible enough, but not every flow can be supported. The flow is supported or not has nothing to do with if it's simple. It's limited to HW capability. Wei, do you have some doc to shared or even has uploaded to the community? Thanks.

Re: [dpdk-users] using rte_flow via tespmd with Intel X552

[Tetsuro Nakamura]

Dear Adrien and Wenzhuo,

Thank you very much for your kind reply.
I tried flow_director_filter API directly using testpmd with the same
environment.
So let me add more information.

- Using pktgen-3.0.13, I prepared 2 flows whose dst-Macs are
 0c:c4:7a:cf:66:11 and 0c:c4:7a:cf:66:12 respectively.
```
Pktgen> set 0 seqCnt 2
Pktgen> seq 0 0 0c:c4:7a:cf:66:11 0c:c4:7a:cf:66:01 192.168.1.1
192.168.0.1/24 1234 5678 ipv4 udp 1 64
Pktgen> seq 0 0 0c:c4:7a:cf:66:12 0c:c4:7a:cf:66:02 192.168.1.1
192.168.0.1/24 1234 5678 ipv4 udp 1 64
Pktgen> start 0
```

- Then I started testpmd with options of "--rxq=2 --txq=2" and
"--pkt-filter-mode=perfect-mac-vlan".
- No error had occurred when configuring flow_director_filter.
- When started, all packets were received in Pktgen.
```
$sudo ./dpdk-17.04/x86_64-native-linuxapp-gcc/app/testpmd -l 0-4 -n 4 -- -i
--portmask=0x3 --nb-cores=4 --rxq=2 --txq=2
--pkt-filter-mode=perfect-mac-vlan

testpmd> flow_director_filter 0 mode MAC-VLAN add mac 0c:c4:7a:cf:66:11
vlan 1 flexbytes (0x80,0x00) fwd queue 0 fd_id 1
testpmd> flow_director_filter 0 mode MAC-VLAN add mac 0c:c4:7a:cf:66:12
vlan 1 flexbytes (0x80,0x00) fwd queue 1 fd_id 2
testpmd> start
```

- When queue 0 was stopped, no packet was received in Pktgen.
```
testpmd> stop
testpmd> port 0 rxq 0 stop
testpmd> start
```

- When queue 1 was stopped, all packets were received in Pktgen.
```
testpmd> stop
testpmd> port 0 rxq 0 start
testpmd> port 0 rxq 1 stop
testpmd> start
```

- which (I guess) mean the flow is not supported as you said.
- The mac argument in flow_director_filter is dst-Mac, right?
