 Log Message:
 PR bin/42464: Timothy McIntosh: Fix timed interoperability
 
 Fix is a combination of FreeBSD fix and submitted patch.
 
 [From the FreeBSD change]
 The timed protocol is not implemented in a compatible way by all
 vendors; the size of the tsp_name field is OS-dependent.  4.3BSD
 used a 32-byte field, FreeBSD uses MAXHOSTNAMELEN and RedHat
 apparently uses a 64-byte field.  As a result, sanity checking code
 added a few months ago to detect short packets will fail when
 interoperating with one of these other vendors.
 
 Change the short packet detection code to expect a minimum packet
 size corresponding to the 4.3BSD implementation, which should be
 a safe minimum size.
