[dpdk-users] Filter tagged frames using Intel Flow Director (XL710)

[Martin Trommer]

Hi devs,


I want to filter tagged frames using the Intel Flow Director by matching the ethertype.

Therefore I make use of the dpdk testpmd app.

What ethertype do I have to configure to match following triple tagged frame ?

Ethernet 0x8100 | VLAN 0x8100 | VLAN 0x8100 | VLAN 0x0800 | IPv4

Do I have to configure something else (vlan offload, ... ) ?


Not working is:

flow_director_filter 0 mode IP add flow l2_payload ether 0x8100 flexbytes () fwd pf queue 4 fd_id 1

neither:

flow_director_filter 0 mode IP add flow l2_payload ether 0x0800 flexbytes () fwd pf queue 4 fd_id 1

The frame is still going to queue 0.



Environment:

Intel XL710 NIC (FW: 5.04)

DPDK 17.05
