[dpdk-dev] vmxnet3 RX VLAN Strip offload incorrect behaviour

[Padam Jeet Singh <padam.singh@inventum.net>]

When configuring the vmxnet3 based ethernet device, the VLAN Strip RX offload does not work as it usually does with other real NICs.

When configuring with rxmode.hw_vlan_strip = 1, the ipackets statistic does 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 = 0 ,the ipackets statistic 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?

Thanks,
Padam
