// In example shown below incoming packet will receive value
// http://[2001:db8::1]/ubuntu.cfg if incoming packet will include user
// class option with "iPXE" in it and value http://[2001:db8::1]/ipxe.efi
// if option client architecture type will be 7.
// If incoming packet will include both of those options with matching
// values it will be assigned to class "a-ipxe" because it was first
// matching class. If you want to change that order names of the classes
// have to have different alphabetical order. In Kea 1.3.0 (and previous
// versions) alphabetical order is used in classification. Note this
// should change in next versions, for instance to keep the definition
// order.
