Hi,
Recently, I wan to use packetdrill to test vpp hoststack . I connet vpp and kernel-protocol-stack with veth. And local client runs on vpp hoststack , remote is on kernel.
local <----> vcl <----> vpp <-----> veth1 <-----> veth0 <-----> remote.
At remote , I just wen to recvive the 2-layer or 3-layer packet, so I use raw sock. However , I meet a problem that raw sock just get the copy of packet that sent by local client , the packet still transfer to the upper layer (4 layer) .And the upper layer will answer the packet , which will influences my test. Since the local client just want to receive the packet that sent by raw sock.
local <----> vcl <----> vpp <-----> veth1 <-----> veth0 <-----> raw sock.

---X--> upper layer .
Do your matter the same problem when testing vpp hoststack ? And do you have good idea about the vpp hoststack test with packetdrill?
Regards,
Longfei
