Bug ID: 107
Summary: Cannot set rte_flow QUEUE action for VF representor
Product: DPDK
Version: 18.11
Hardware: x86
OS: Linux
Status: CONFIRMED
Severity: normal
Priority: Normal
Component: ethdev

Target Milestone: ---
Hi all,
I'm trying to direct a given flow directly to a VF's specific queue.
Steps to reproduce:
sudo ./testpmd -w "pci:03:00.1,representor=0" -- -i
EAL: Detected 16 lcore(s)
EAL: Detected 2 NUMA nodes
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Probing VFIO support...
EAL: VFIO support initialized
EAL: PCI device 0000:03:00.1 on NUMA socket 0
EAL: probe driver: 15b3:1017 net_mlx5
net_mlx5: port 1 ioctl(SIOCETHTOOL, ETHTOOL_GSET) failed: Operation not
supported
Interactive-mode selected
testpmd: create a new mbuf pool <mbuf_pool_socket_1>: n=203456, size=2176,
socket=1
testpmd: preferred mempool ops selected: ring_mp_mc
testpmd: create a new mbuf pool <mbuf_pool_socket_0>: n=203456, size=2176,
socket=0
testpmd: preferred mempool ops selected: ring_mp_mc

testpmd> flow create 1 ingress pattern eth dst is 1e:00:b6:cb:66:e4 / end

Expected results:
- I can understand the first line, doing both VF and queue at the same time is
hard to support.
- The second line works and send packets to the VF. (Why can't I use the VF
action by the way? And why do I need transfer for PF to VF?)
- The third line does not work because the VF representor has a single queue
(the real VF has 8). Now at the end of the EAL lines I get 'net_mlx5: port 1
ioctl(SIOCETHTOOL, ETHTOOL_GSET) failed: Operation not supported.'. Is that a
failing ethtool -L ?
- However if I use queue 0, it is accepted but does not work anyway (I get a
random RSS choosen index).
I hope the answer is not "line 4" should fail, because I'd really like to be
able to do this without having to send rules from the VF itself (if that
works).
