# Test script wrapper for running ODP pktio apps on linux-generic.
#
# For linux-generic the default behavior is to create two pairs of
# virtual Ethernet interfaces and provide the names of these via
# environment variables to pktio apps, the interfaces will be removed
# before the script exits.
#
# Note that the creation of virtual Ethernet devices depends on having
# CONFIG_VETH enabled in the kernel, if not enabled the env setup will be skipped.
