+## XDP L2 forwarding
+xdp\_l2fwd handles Layer 2 forwarding between an ingress device (e.g., host
+devices) and egress device (e.g., tap device for VMs or other host device). 
+Userspace populates an FDB (hash map) with \<smac,dmac> pairs returning an
+index into a device map which contains the device to receive the packet.
+See scripts/l2fwd.sh for an example.
+
+This program is used for the netdev 0x14 tutorial, XDP and the cloud: Using
+XDP on hosts and VMs https://netdevconf.info/0x14/session.html?tutorial-XDP-and-the-cloud
+
+## Using l2Fwd
+
+1. Go to vineperf/src/bpfswitch/ folder.
+2. First run configure script and then run make 
+3. Go to scripts/ folder and open l2fwd.sh file
+4. Update values of TGEN<EAST/WEST>MAC, <EAST/WEST> Interfaces and their indexes.
+5. Use ifindex.py to know the indexes.
+5. Ensure that path of bpftool is correc in the file.
+6. Save changes and run the script.
+7. If successfully run the setup is ready to test loopback
+
+## Dummy XDP program
+
+xdp\_dummy is a dummy XDP program that just returns XDP\_PASS.
