Hi,

I am trying to send a packet to a local interface hosted on 128.0.0.16 IP in the same Linux machine (kind of loop back). I had opened a RAW socket and sending packets using sendto(). In the TCPDUMP, the IP header seems to be properly formed by the IP stack. But the Ethernet header seems to be messed up. Destination MAC (00:00:03:04:00:06) looks incorrect and the Source MAC is 0. Also i see an additional 2 bytes of 0s before IP EthType.

Can someone be able to help me with this? This packet is not reaching the destination socket (in the same Linux m/c).

06:23:22.584828 IP dvc0 > dvc0: ip-proto-84 80
0x0000: 0000 0304 0006 0000 0000 0000 0000 0800 <=====
