BFD session status notification

[Winston Chen]

Hi,

Thanks for the info.
I am running bird along with my application inside a container. And bird
log is collected by my application.  So installing another log daemon is
not necessary/practical to me.
I did a little more study on the code. And it looks like I can send the
notification in some BFD event hook. Is there any chance this idea can be
accepted? If yes, I can do some work after I finish the tasks in my hands.

Regards.
