[lldp-devel] [PATCH] lldpad: Document shutdown behavior

Document the fact that lldpad does not undo any of the
configuration that it has performed when it terminates.
The main use cases for termination are restarting due
to an update and during system shutdown. In both cases,
things are probably best left in their existing state.
This patch documents this behavior.

+.SH NOTE
+On termination, lldpad does not undo any of the configurations that
+it has set. This approach minimizes the risk of restarting the daemon
+to perform a software update, or of having storage issues during
+shutdown. Ongoing operation of network interfaces that had been
+controlled by lldpad may result in unexpected behavior.
