Problem Description: 

Bug 1189108: x25mod unload undefined error. This error was introduced in 
	     version -03 of the patch. The patch install correclty but at
	     X25 startup the error -
		/usr/kernel/strmod/x25mod:undefined symbol x25mod.printf
	     is reported. The end result of this is that x25mod will not
	     load.

Bugs fixed in version -03 of the patch:

Bug 1186895: X25 clears call with 00 43 (invalid called address) under
	     some circumstances where the called address is actually
	     correct. This is because x25 tries to access a message block
	     it has already freed. This only showed up running under a 
	     debug kernel and should not be confused with valid call clears
	     occurring with 00 43.

Bug 1182028 : Ioctl(X25_RD_LCGN) would return permission denied if not root.

Bug 1182813 : At link establishment time, X25 would send a restart packet with
              a reason of 0, regardless of the level 3 configuration ( DTE or
              DCE ). This value is incorrect when being DCE.

Bug 1181238: HDLC RNR sent out under heavy system load. This busy condition
	     will not clear within a reasonable time and can cause disconnects
	     with some X25 switches whihc do frame buffering.

Bug 1115515: X25 Licences lost messages reported. there are two causes of
	     this problem. This bug relates to a problem in the LAPB driver
	     but the problem can also occur if using the X25 socket interface.
	     The fix to the problem in the socket interface is also in this
	     patch.

Bug 1163811: Using the socket interface, when the link we listen to has been
             restricted with ioctl(X25_SET_LINK), accept() doesn't return the 
             calling address.

Bug 1186448: Wrong address length returned by ioctl(X25_RD_REMOTE_ADR) or
             ioctl(X25_RD_LOCAL_ADR) in the x25 socket interface.

Bug 1179703: fmli depends on openwin libxview.so.3 for installation

Bugs fixed in version -02 of the patch:

Bug 1177446: Impossible to use CUG selection with IP/X25

Bugs fixed in version -01 of the patch:

Bug 1175496: Insert at bottom of list in x25tool occassionally corrupts
             the whole list
Bug 1175497: Race condition with inbound calls can give rise to incorrect
             matching results
Bug 1175498: linkstop utility does not always bring the link down correctly

Bug 1175516: When in REJ state RR frame gets sent without updating Vr after
             rxmit frame

Additional changes in -01:

        1. Various internal changes to the HDLC and X25 socket interfaces to
           improve compatibility with 7.0 behaviour.
        2. Max number of IP networks configurable increased from 8 to 124
        3. Pad parameter 10 now accepts zero as a valid value.
        4. When a VC is disconnected the hangup message is now an M_HANGUP
           instead of a M_SIG || M_HANGUP which means that the hangup is
           delivered to the process group leader not to the foreground process.
        5. Changes to x25tool to reflect increased number of VC's configurable
        6. padd no longer rejects occasional valid inbound calls. Also, almost
           simultaneous inbound pad calls no longer cause padd to exit
           occasionally.
        7. locking has been added to iflayer to allow multiple simultaneous
           invocations of the command.
        8. llc2 driver no longer returns an L_SETLINKID error when using a
           linkid of zero for an llc2 link.
