// if exists dhcp6.client-arch-type and
//    option dhcp6.client-arch-type = 00:07 {
//    option dhcp6.bootfile-url "http://[2001:db8::1]/ipxe.efi";
// } else if exists dhcp6.user-class and
//          substring(option dhcp6.user-class, 2, 4) = "iPXE" {
//    option dhcp6.bootfile-url "http://[2001:db8::1]/ubuntu.cfg";
// }
//
// 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.
