The maximum size for most RSVP messges is the interface's MTU size,
since an RSVP message must fit entirely into a single non-fragmented IP
datagram.

The one exception is a bundle message (one of the RSVP extensions in RFC
2961).  Bundle messages may be as large as an IP datagram, since they
may be fragmented.  This means a maximum size of 64K.
