Fortville X710 FDIR with flow APIs broken
https://bugs.dpdk.org/show_bug.cgi?id=449
Bug ID: 449
Summary: Fortville X710 FDIR with flow APIs broken
Product: DPDK
Version: 20.02
Hardware: x86
URL: https://doc.dpdk.org/dts/test_plans/generic_flow_api_t
est_plan.html
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: Normal
Component: eventdev
Assignee: [email protected]
Reporter: [email protected]Target Milestone: ---
DPDK version tested: 19.11.1 & 20.2
section: 28.5, Flow config for VF-0 for ipv4-other
Rule:
1. flow create 0 ingress pattern eth / ipv4 src is 192.168.0.1 dst is 192.168.0.2 proto is 3 / vf id is 0 / end actions queue index 1 / end
2. flow create 0 ingress pattern eth / ipv4 src is 11.11.11.11 dst is 12.12.12.12 proto is 17 / vf id is 0 / end actions queue index 1 / end
3. flow create 0 ingress pattern eth / ipv4 proto is 17 / vf id is 0 / end actions queue index 1 / end
Result: `Caught error type 13 (specific pattern item): cause: 0x17ff5b140, Matching VF traffic without affecting it (transfer attribute) is unsupported:
Operation not supported`
CMD:
a. PF: ``` ./x86_64-native-linuxapp-gcc/app/testpmd -l 14-15 -w 08:00.0 --socket-mem=128 -- -i --rxq=4 --txq=4 --disable-rss --pkt-filter-mode=perfect```
b. VF: ```./x86_64-native-linuxapp-gcc/app/testpmd -l 16-17 -w 0000:08:02.0 --socket-mem=128,0 --file-prefix=vf -- -i --rxq=4 --txq=4 --disable-rss --pkt-filter-mode=perfect```
on both:
``` set fwd rxonly set verbose 1 start ```

--- Comment #13 from Steve Yang ([email protected]) --- Not a bug.
Correct use steps：
1. bind the pf to dpdk driver::
./usertools/dpdk-devbind.py -b igb_uio 1b:00.0
2. add one vf on dpdk pf, then bind the vf to vfio-pci::
echo 1 >/sys/bus/pci/devices/0000:1b:00.0/max_vfs
./usertools/dpdk-devbind.py -b igb_uio 1b:02.0
3. launch the app ``testpmd`` with the following arguments::
./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -w 1b:00.0
--file-prefix=pf – -i --rxq=4 --txq=4
testpmd> set verbose 1
testpmd> start
./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -w 1b:02.0
--file-prefix=vf – -i --rxq=4 --txq=4
testpmd> set verbose 1
testpmd> start
4. create filter rule and sent pkg::
flow create 0 ingress transfer pattern eth / ipv4 src is 11.11.11.11 dst is 12.12.12.12 proto is 255 / vf id is 0 / end actions queue index 1 / end
sendp([Ether(dst='3C:FD:FE:DC:F1:88')/IP(src='11.11.11.11',dst='12.12.12.12',proto=255)/("X"*480)], iface="enp27s0f1", count=1)
5. flow create 0 ingress transfer pattern eth / ipv4 src is 11.11.11.11 dst is 12.12.12.12 / udp / vf id is 0 / end actions queue index 1 / end
sendp([Ether(dst='3C:FD:FE:DC:F1:88')/IP(src='11.11.11.11',dst='12.12.12.12',proto=17)/("X"*480)],iface="enp27s0f1", count=1)
Note:
① dst mac is a random mac address, not a pf mac
② proto is 17 means UDP, so create the following rule and send the packet with proto is 17 cannot matched。
flow create 0 ingress transfer pattern eth / ipv4 src is 11.11.11.11 dst is 12.12.12.12 proto is 17 / vf id is 0 / end actions queue index 1 / end
sendp([Ether(dst='3C:FD:FE:DC:F1:88')/IP(src='11.11.11.11',dst='12.12.12.12',proto=17)/("X"*480)], iface="enp27s0f1", count=1)

Resolution|INVALID |---
Status|RESOLVED |CONFIRMED--- Comment #14 from Vipin Varghese ([email protected]) --- Marking this as fixed confirmed rather than resolved-invalid due to the following reasons
1. ticket is opened on DPDK 20.02 on 13 Apr 2020
2. The documentation available for FDIR on X710 was not correct
3. missing of transfer verb in the documentation of testpmd and tests.
4. Patches and fixes applied on top of X710 before testing on 30 Dec 2020.
5. Not mentioned in the comment whether it works for DPDK 20.02
6. Have not confirmed if the VF can be used with any other application other than testpmd.
@Ajith will test and try on DPDK 20.02 but with much lower priority to confirm with the steps shared from Steve Yang and update the ticket.
