DPDK memif driver

[Raghavender]

Hi,

Currently dpdk memif code indicates that it can support only MEMIF_INTERFACE_MODE_ETHERNET mode.

Code: dpdk-20.11.1/drivers/net/memif/memif_socket.c

if (i->mode != MEMIF_INTERFACE_MODE_ETHERNET) {
memif_msg_enq_disconnect(pmd->cc,
"Only ethernet mode supported",
0);
return -1;
}

Is there a way memif can support pure raw buffer mode? So that pure raw buffer can be sent/received without any IP / UDP headers?

If we just allow the mode with MEMIF_INTERFACE_MODE_PUNT_INJECT, will it be able to handle raw buffer mode ? OR without IP/UDP headers the packet will be dropped by any other node from dpdk side ?

Can someone pls share the ideas / thoughts on this part?

Along with this is there a way we can test dpdk with memif in a standalone environment?

Thanks & Regards,

Raghavender.
