Hi Cristian,
OK, thank you for the reply.
Are you/anyone aware of a virtual driver that implements at least some
level of rte_flow support?
Thanks in advance.

Subject: Initialize SoftNIC to work with rte_flow rules
Hi all,
I am trying to setup completely virtual development environment where it
would be possible to develop applications with rte_flow rules.
For this, I've found SoftNIC as a viable solution as this is supposed to
be a software NIC that also supports rte_flow rules.
However, I am having a hard time to set it up, I couldn't find good
examples/documentation for this. Examples/docs found in
ip_pipeline/pipeline examples are outdated.
I was able to make it run through testpmd but without the support for
rte_flow.
Could you please help me to create spec/cli file that would support this
use case?
I am currently primarily interested in RX direction although being able
to work in the TX direction would be greatly appreciated.
The solution I am currently thinking of:
net_pcap0 -> net_softnic0 -> DPDK application + TX( -> net_softnic0 ->
net_ring/net_null)
The RX path can be done - and I was able to run it in testpmd but then
testpmd complained when I tried to apply rte_flow rules (not
implemented). Makes sense considering that the softnic default pipeline
doesn't contain any tables I guess.
Thank you all in advance.
I'm CC'ing Cristian as he is the SoftNIC maintainer.
Cheers,
Lukas Sismis
Hi Lukas,
The Soft NIC driver does not currently have RTE_FLOW support.
For now, you have to use the DPDK pipeline-specific API for populating the
pipeline tables:
1. You can put these commands in the firmware.cli file to be run at
Initialization.
2. You can use the run-time CLI (the best option) by doing "telnet 0.0.0.0 8086"
after the device initialization is complete. In case you're using test-pmd,
beware
of the change required, as stated in the default
"drivers/net/softnic/firmware.cli"
file.
3. You can call the C API directly in your app.
Regards,
Cristian
