Add a sample userspace program which can be used with the VOP framework
with vop-loopback and non-MIC hardware.
For example, the following commands can be used to test networking over
vop-loopback. (IPv6 is used with zone indices to force traffic through
the interfaces instead of short-circuit delivery, since both interfaces
are on the same system.)
# modprobe vop_loopback
# ./vopd &
Setup host interface:
# ip a a dev mic0 scope link fe80::0
# ip link set dev mic0 up
Setup guest interface:
# ip a a dev eth1 scope link fe80::1
# ip link set dev eth1 up
Ping from host to guest:
# ping6 fe80::1%mic0
Ping from guest to host:
# ping6 fe80::0%eth1
