# This test is for checking the [no]localbypass VXLAN device option. The test
# configures two VXLAN devices in the same network namespace and a tc filter on
# the loopback device that drops encapsulated packets. The test sends packets
# from the first VXLAN device and verifies that by default these packets are
# received by the second VXLAN device. The test then enables the nolocalbypass
# option and verifies that packets are no longer received by the second VXLAN
# device.
