+modification history
+--------------------
+01n,08jan10,dbt  Increased WDB END driver MTU (support for fragmented packets
+                 have been added in driver).
+01m,07dec05,dbt  Replaced bool_t with BOOL.	
+		 Cleanup header files inclusion
+01l,10feb04,dbt  Decreased MTU to 512 to avoid packet fragmentation (this is
+                 not supported with WDB END driver).
+01k,26apr02,dat  Adding cplusplus protection, SPR 75017
+01j,30oct01,jhw  Copied version TOR3_1-RC-1.
+01i,02aug99,dbt  added WDB standalone agent support.
+01h,26feb99,dbt  set WDB END driver MTU to 1500.
+01g,25sep97,gnn  SENS beta feedback fixes
+01f,22aug97,gnn  update of polled mode.
+01e,19aug97,gnn  changes due to new buffering scheme.
+01d,21jan97,gnn  added a source NET_ADDRESS.
+01c,04nov96,gnn  change the MTU size
+01b,23oct96,gnn  name changes to follow coding standards
+01a,01jul96,gnn  written.
