    etc                  network.subr 
  Log:
  Fix get_if_var() with 3 args (i.e. with default)
  
  All xxx_<ifname> flags are set to empty strings automatically earlier so
  eval echo \${${prefix}${_if}${suffix}-${_default}}
  not substitute the default but return just the empty string.
  Fix it using
  eval echo \${${prefix}${_if}${suffix}:-${_default}}
  (i.e. treat empty strings as unset)
  
  The bug manifistates itself with the following warning from checkyesno():
  /etc/rc.d/dhclient: WARNING: $background_dhclient is not set properly -
  see rc.conf(5)
