Rx, right before returning them to the application to avoid starvation.
I do not think DPDK applications are ready for 2 and 3 yet. Also due to the
above, doing so would require extra work on the PMD side.

that into the remaining queues (QUEUE or RSS action depending on the

The ixgbe driver looks like it does but I'm not sure regarding the VF
variant, Cc'ing maintainers just in case.

never had a chance to use this pattern item with any PMDs
that support it, so I don't know close their behavior sticks to what I just
described, especially regarding the handling of mask.pattern. Do not

dispatch it to a different queue.
Question is which drivers implement this use case. While I'm aware mlx5
supports PF/VF/representor redirections, I don't know if a VF can feed its
own representor like that. A true hairpin action is missing anyway.

This means a mere user can't use them. In which case you need to chown/chmod
or remove them altogether.
Have you tried --no-huge?

If acceptable for your application, then you may try something like:
root# setcap cap_net_admin,cap_net_raw,cap_ipc_lock=ep ./build/l2fwd
user$ ./build/l2fwd [...]
Note the described approach adds capabilities through extended device
attributes on the file system (those are rarely preserved when copying
files). While finer grained than "chmod +s", you still need to carefully
consider the security implications, trust the program and its users.
Have a look at man capabilities(7).

Referring to a port with this name through the above function should yield
the correct device.

The related patches have been submitted and are on track for DPDK 17.11.
While they are not yet on the master tree, you can find them on

u likely need to transfer the associated netdevices to
your Docker instance for this to work though. You'll likely need to somehow
transfer the related IB instances as well.
At least that's the theory, I've never personally tried to use Docker with
mlx4/mlx5 VFs.

device was not configured properly.
Try to white-list the devices you want to use by explicitly providing their
PCI bus addresses through -w arguments instead.

llowing 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?

ew features will still be missing such as setting interfaces up and down,
updating MTU of the physical link and so on, basically all netdevice
operations that are not queries. Those can be performed as super-user on the
related netdevice directly from a separate process, even before starting the
DPDK application.

x4*.so* on your system, make
sure DPDK links against OFED's version. I suggest uninstalling all previous
versions to be sure.
Check also that you do not have both /usr/include/infiniband and
/usr/local/include/infiniband.
