VPP-side config:
```
-DBGvpp# create memif id 0 master
+DBGvpp# create interface memif id 0 master
DBGvpp# set int state memif0/0 up
DBGvpp# set int ip address memif0/0 192.168.1.1/24
```
```
conn 0 0 1
```
-> Last argument specifies interrupt function to use. This function only respondes to ARP requests. This is important because, packet generation and transmitting is handled by a separate thread. Calling memif_tx_burst from multiple threads writing on same queue could transmit uninitialized buffers.

Once connection is established, you can send ping from VPP to icmpr-epoll app to learn its mac address.
