ok, then just don’t do it until problem is properly addressed in i40e.

I don't think using vlans in performance testbeds is good idea.
I would simply avoid using it…

//quote
If you have applications that require Virtual Functions (VFs) to receive
packets with VLAN tags, you can disable VLAN tag stripping for the VF. The
Physical Function (PF) processes requests issued from the VF to enable or
disable VLAN tag stripping. Note that if the PF has assigned a VLAN to a VF,
then requests from that VF to set VLAN tag stripping will be ignored.

So unless this is a bug, then it means that application should not enforce the 
behavior.

Juraj. Does this detection works on DPDK testpmd? 
https://doc.dpdk.org/dts/test_plans/vlan_test_plan.html
If this is indeed unsupported on new driver level and firmware, then removing 
700 series is the only option to me.

To me this is as simple as to:
 =  disable_vlan_stripping()
if error:
  vlan_cannot_stripped_flag == 1 # ignore the error.

Thoughts?

Or simply declare it as unsupported until intel introduces V2 api in the i40e.

Hi Damjan,

Just pinging to get your thoughts. I really seems like we should introduce some 
sort of switch in the absence of an API.

If there isn't an API for this, then we'll have to get this information from 
the user, right?

Or we could try enabling stripping but not fail the interface initialization if 
it's not successful.

Thoughts?

OK, I was hoping new version of driver supports VLAN v2 offload APIs which 
allows us to know if stripping is supported or not on the specific interface. 
V2 API is already supported on ice driver (E810 NICs) and we have code to deal 
with that.

So not sure what we can do here. I don’t see a way to know if stripping is 
supported or not.

It looks like this feature (vlan stripping on VFs with VLANs) was removed in 
later versions of the driver. I don't know what the proper solution here is, 
but adding a configuration option to not disable vlan stripping when creating 
AVF interface sound good to me.

I've documented this in https://jira.fd.io/browse/VPP-1995.

Can you try with 2.16.11 and report back same outputs?

I've updated https://jira.fd.io/browse/VPP-1995 with 2.16.11 outputs and 
they're pretty much the same, except the last syslog line is missing.

I just updated https://github.com/dmarion/deb-i40e in case you are using it…

Thanks, we're currently using the intel download pages, but it may be easier to 
use your repo, so we'll keep it in mind for the future.

Juraj

[vpp-dev] AVF interface creation fails on VFs with configured VLAN with newer i40e drivers
