# get the interface and check if it is available or up
#
# If your script needs a base interface upon which the new interface resides
# (e.g. for tunnels) then pay attention to the following:
# Imagine you have a variable BASE_DEVICE in your configuration which you expect
# to contain the interface name of the base interface. This variable may contain
# any valid description of the base device and need not to be an interface name.
# Moreover it is recommended to prefer an device description to the interface
# name, because interface names are not always persistent the may change. See
# man ifup for valid device descriptions. You will get the current interface
# name to this device with /sbin/getcfg-interface:
#
# BASE_INTERFACE=`/sbin/getcfg-interface -- $BASE_DEVICE`
#
# if ! is_iface_available $INTERFACE ; then
# logerror "interface ${INTERFACE} is not available"
