Doc Type: Bug Fix
Doc Text:
If a mirror or redirection action is configured to cause packets to go to another device, the classifier holds a reference count. However, it was previously assuming that the administrator cleaned up all redirections before removing. Packets were therefore dropped if the mirrored device was not present, and connectivity to the host could be lost. To prevent such problems, a notifier and cleanup are now run during the unregister action. Packets are not dropped if the a mirrored device is not present.
