# xdping tests
#   Here we setup and teardown configuration required to run
#   xdping, exercising its options.
#
#   Setup is similar to test_tunnel tests but without the tunnel.
#
# Topology:
# ---------
#     root namespace   |     tc_ns0 namespace
#                      |
#      ----------      |     ----------
#      |  veth1  | --------- |  veth0  |
#      ----------    peer    ----------
#
# 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.
#
