+Subject: alfred: Show error message for invalid batadv interface
+
+The alfred server process always stopped without any informational message
+when the provided batman-adv was not "none" and was not accessible. This
+made it extremely hard to debug the reason why alfred directly stopped
+after launching it.

+Subject: alfred: Allow exactly one interface for secondary mode
+
+A primary alfred daemon allows syncing over more than one interface. But
+the secondary alfred daemon needs exactly one interface. But the check for
+this property was insufficient because it allowed paramters like
+"-i wlan0,asd" when wlan0 is valid and asd is not valid.
+
+The better solution is to really use the number of interfaces given to
+alfred instead of the number of interfaces evaluated as "valid".
+
+Fixes: 67ae5f57eedd ("alfred: Add support for multiple interfaces per master")

+Subject: alfred: Allow start of server without valid interface
+
+The alfred server always needs interfaces to operate on. But these
+interfaces might not exist at the moment when the daemon process is
+started. This caused an error and stopped the process.
+
+But alfred is able to deal with interfaces which disappeared at runtime but
+existed at startup. To force a similar behavior for the alfred startup, the
+parameter "--force" or "-f" is introduced.
