This repository won't be updated until generic-ebpf become stable.

VALE-BPF module is an extension of VALE software switch.

This module makes VALE possible to program with eBPF. It uses generic-ebpf as a backend eBPF system. It may works on the platform which both of generic-ebpf and netmap are supported.

• generic-ebpf
• netmap

Assume you already installed netmap and generic-ebpf on your system. Please see the documentation of them for more details.

Create switch named vale0 and attach two interfaces

# vale-ctl -n vi0 //interface 0
# vale-ctl -n vi1 //interface 1
# vale-ctl -a vale0:vi0 //attach interface 0 to vale0
# vale-ctl -a vale0:vi1 //attach interface 1 to vale0

$ make
# make load

Now module is loaded to vale0. However, eBPF program is not yet loaded. You need to load eBPF program. Below is an example of running sample application.

$ cd benchmark/vale-bpf/l2_bridge
# ./l2_bridge_loader -v vale0
