+ *
+ *
+ * This library is based on H.225 version 4, H.235 version 2 and H.245
+ * version 7. It is extremely optimized to decode only the absolutely
+ * necessary objects in a signal for Linux kernel NAT module use, so don't
+ * expect it to be a full ASN.1 library.
+ *
+ * Features:
+ *
+ * 1. Small. The total size of code plus data is less than 20 KB (IA32).
+ * 2. Fast. Decoding Netmeeting's Setup signal 1 million times on a PIII 866
+ *    takes only 3.9 seconds.
+ * 3. No memory allocation. It uses a static object. No need to initialize or
+ *    cleanup.
+ * 4. Thread safe.
+ * 5. Support embedded architectures that has no misaligned memory access
+ *    support.
+ *
+ * Limitations:
+ *
+ * 1. At most 30 faststart entries. Actually this is limited by ethernet's MTU.
+ *    If a Setup signal contains more than 30 faststart, the packet size will
+ *    very likely exceed the MTU size, then the TPKT will be fragmented. I
+ *    don't know how to handle this in a Netfilter module. Anybody can help?
+ *    Although I think 30 is enough for most of the cases.
+ * 2. IPv4 addresses only.
