+ * {ioctl,kernel}_null.c: Dummy/Null kernel method implementations,
+ useful for testing zebra code that calls such methods.
+ * {redistribute,misc}_null.c: Dummy/Null methods, as above. But
+ for zclient, and for various misc functions.
+ * test_main.c: Test harness for zebra, currently just to test the
+ RIB.
+ * Makefile.am: Build testzebra using above.
+ * zebra_rib.c: Add a global for the workqueue hold time, useful
+ for testing.

2006-07-27 Rumen Svobodnikov <rumen@telecoms.bg>
* connected.c: (connected_up_ipv4) interface connected routes always
