"""Routines for handling Ethernet OUI information.
"""

# The IEEE publishes an enormous list of registered Ethernet OUIs,
# but we don't benefit from having that entire list here. Instead
# we track the OUIs which let us distinguish devices which are
# otherwise very similar, such as distinguishing LG G2 from Samsung
# Galaxy S4.
