# Device Configuration

# --------------------

# Root namespace with BPF

# Device names and addresses:

# veth1 IP: 10.1.1.200

# xdp added to veth1, xdpings originate from here.

# Namespace tc_ns0 with BPF

# Device names and addresses:

# veth0 IPv4: 10.1.1.100

# For some tests xdping run in server mode here.
