I have the following configuration: - host runs with Linux pf i40e driver(version 2.4.6) - guest runs with DPDK 17.11.2 vf i40e driver When I am sending a vlan packet from the outside to the guest, on the guest= , I receive the packet which has the PKT_RX_VLAN_STRIPPED flag set although= I'm not asking for it. Even though my DPDK app has the rte_eth_conf.rxmode.hw_vlan_strip set to 0 = and also verified that the i40evf_disable_vlan_strip(VIRTCHNL_OP_DISABLE_VL= AN_STRIPPING) function is getting called and not returning any error from t= he linux pf driver. Is this the default behavior that the VLAN will be always stripped by the P= F irrespective of the setting ? Should the DPDK version take care of the re= -adding the tag back to the packet in case hw_vlan_strip is disabled ? What= should be best way of handling it ? Is it a bug in DPDK or I am missing so= mething here. I do see in the linux i40evf driver we are insert vlan header in the receiv= ed packets in some cases. -- Regards, Souvik
