Andrew Thompson febd0759f3 Change the reference counting to count the number of cloned interfaces for each ... cloner. This ensures that ifc->ifc_units is not prematurely freed in if_clone_detach() before the clones are destroyed, resulting in memory modified after free. This could be triggered with if_vlan. Assert that all cloners have been destroyed when freeing the memory. Change all simple cloners to destroy their clones with ifc_simple_destroy() on module unload so the reference count is properly updated. This also cleans up the interface destroy routines and allows future optimisation. Discussed with: brooks, pjd, -current Reviewed by: brooks		2005-10-12 19:52:16 +00:00
