What OFED version do you use? Or OOB kernel driver/rdma-core?
Target table (1 in the mentioned patch) is created on the flow creation as empty one.
The default rule for the empty ingress table in FDB (transfer attribute in testpmd command)
– go to vport 0 (to wire/VF representors), it is established by kernel/rdma-core, In your setup
it does not work.

With best regards, Slava

Subject: mlx5: the default rule makes VF rep cannot get packets


We found the patch "net/mlx5: revert default rules amount optimization",
which installs a rule directing all egress traffic from VF to table 1, results in
VF representors get no packets, even if there is no offload rules installed.

I’ve tested both l2fwd and ovs-dpdk.  However, PF rep works just fine.

We are using dpdk 19.11-rc3 for evaluation.
