How to use vpp quic-plugin based VCL socket as a netdev ?

[batmancn]

Hi, all,

In my use case, I need to use a VCL socket, which is based on quic-plugin, as a netdev to add into a bridge domain. Detail is like this:

eth0(take over by DPDK) ---- bridge domain ---- qs1(quic socket create by VCL) 

The packet received in eth0(which is under DPDK) is treated as a block of memory.
Then the packet(treated as a block of memory) is send by qs1(quic socket create by VCL).

How to implement this case in vpp25.02 or above?

I search this, and said there are tow way:

1. use memif;
2. use Protocol-as-a-Device;

And the Protocol-as-a-Device is better, so is there some code about this?

Thanks !!!

So my question is:

1. how to implement this case by memif?
2. how to implement this case by Protocol-as-a-Device?
