I have a problem trying to get VLAN tagged frames to be received at the i40evf
PMD.
Specifically, there is no connectivity on VMware i40e media interface
configured as SR-IOV when VLANs are used, but it works fine for non-VLAN tagged
frames. It seems the VLAN headers are being stripped

With more debugging enabled, I can see that this seems to be a compatibility
problem between DPDK and i40evf related to VLAN ha

Hi all,
I'm trying to build 17.11.1 against libibverbs from OFED 4.2-1.0.0.0 but having
some API compatibility issues.
According to the DPDK docs, that's the correct version for DPDK 17.11

But I get

I posted my observations on the same issue a year or so ago...
See my follow-ups on this thread for a patch to work around the problem:

Note that the patch has real-time overhead so was rejected.
But we are using it to good effect in
Does anyone use DPDK with VLAN on SR-IOV VF for i40en NIC driver under VMware ?
It seems new 'security' in the Intel i40en driver broke the ability for DPDK to
set VLAN filters for SR-IOV.
Specifically, the VF has to be manually set as 'trusted mode' via a CLI command
to allow more than 8 VLAN
