[OpenWrt-Devel] [PATCH 1/1] netifd: add pre-up/down post-up/down callback handling

[Florian Eckert]

In some situations it is useful to execute callback scripts when
manually triggering an ifdown/ifup event via the CLI/LuCI.

In my case I have a monitoring for a cellular connection.
If this fails the command `ubus call network.interface up` is execute to
restart the connection if a config option in uci of the interface
(keep_connected) flag is set.

But for me to disconnect correctly I need to know about a user
interaction with performed with CLI/LuCI.

With this change we can decide if this is a user interaction with CLI/LuCI,
because with the new callback mechanism I can set/delete a uci config flag so
that the connection should really disconnected. And so does not restart on a
failed connetion tracking again because the uci config flag is not set.
