When configuring with rxmode.hw_vlan_strip =3D 1, the ipackets statistic do= es not increase when a VLAN ether type frame is received on the port and it= is also not received on queue RX. However, when configuring rxmode.hw_vlan_strip =3D 0 ,the ipackets statisti= c increases as well as frames arrives with VLAN header. Though calling rte_eth_dev_set_vlan_offload(port, ETH_VLAN_STRIP_OFFLOAD) = returns a success, however VLAN stripping on RX does not work. TX VLAN INSERT offload on the other hand works just fine. Is this a bug in vmxnet3 driver of dpdk?
