I think it's just:

 @idevid.add_extension(extension_factory.create_extension(
    "subjectAltName",
    sprintf("otherName:1.3.6.1.4.1.46930.1;IA5STRING:%s",
    self.sanitized_eui64),
    false))

Although I think "IA5" and "IA5STRING" are equvivalent here.

The table is at: openssl/crypto/asn1/asn1_gen.c.  If it's in a document
somewhere, I never found it.
