[dpdk-users] rte flow does not work on X550 - "Not supported by L2 tunnel filter"

[Uiu Uioreanu]

Hi,

I am trying to use rte flow on a X550 (ixgbe) and it does not work.

For example, I used testpmd (sudo ./testpmd -c 0xf -n 1 -- -i) to
validate some simple flow rules:
- flow validate 0 ingress pattern eth / ipv4 / udp / end actions drop / end
- flow validate 0 ingress pattern eth / ipv4 / udp / end actions end
- flow validate 0 ingress pattern eth / end actions drop end
- etc

Every time, I receive "caught error type 9 (specific pattern item):
cause: 0x7ffddca42768, Not supported by L2 tunnel filter".
I also tried to make a sample application to use rte flow, but it also
gives the error 9 and the "Not supported by L2 tunnel filter" message.

I don't understand what the problem is. Is the pattern from the flow
validate command wrong? Does the port need any additional
configuration? (except from binding a X550 NIC to
igb_uio/uio_pci_generic)?

I am using DPDK 17.11.

Thanks,
Uiu
