Hi, We were trying to forward packets with vlan id as 0. But the packet is getting altered when we do so. The IP flag and the destination port fields are getting changed. We doubt if this is happening in DPDK because till the rte_eth_tx_burst API, the packet is proper. But the packet captured at the destination is altered. Could you please let us know if there is support in DPDK for forwarding packet with vlan id 0 or if we are missing something.
