# I have no idea what the '4' represents. Watch the warnings/errors
# to verify the number is correct. And from src/constants.h:
#  #if LIBNET_RELEASE >= 4
#    {"HSRP_H", LIBNET_HSRP_H},
#    ...
#
# If you compiled libnet with libnet_build_hsrp.c, you can probably
# safely set '-DLIBNET_RELEASE=4'.
