[bgpd] Bug #302, bgpd can get stuck in state Clearing
2006-12-07 Paul Jakma <paul.jakma@sun.com> * bgp_fsm.c: Bug #302 fix, diagnosis, suggestions and testing by Juergen Kammer <j.kammer@eurodata.de>. Fix follows from his suggested fix, just made in a slightly different way. (bgp_event) Transitions into Clearing always must call bgp_clear_route_all(). (bgp_stop) No need to clear routes here, BGP FSM should do it.
