+Subject: [PATCH] ospfd: fix internal ldp-sync state flags when feature is
+ disabled
+
+When enabling "mpls ldp-sync" under "router ospf" ospfd configures
+SET_FLAG(ldp_sync_info->flags, LDP_SYNC_FLAG_IF_CONFIG) so internally knowing
+that the ldp-sync feature is enabled. However the flag is not cleared when
+turning of the feature using "nompls ldp-sync"!
