Hi, It looks like dpdk_device_input() - is not checking if there is a vlan header in the packet or not and always sets the buffer->current_data to 14 (smac+dmac+ethtype). Because of that ip4_input is not able to recognize a correct IP packet.
For example, I have a subinterface created with vlan100 - which is trying to send IP packets. The receiving side is setting l3offset to 14 and feeding the packet to ip4-input-no-checksum and is getting dropped there. Am I missing something? "show interface" shows the main and the sub interface. "show trace" for dpdk_input shows the vlan tag as 100. But ip4_input_inline gets a buffer with current_data as 14 instead of 18 (accounting for vlan header) Thanks, -nagp
