From: Daniel Willmann dwillmann@sysmocom.de

The current code tries to recover from dropped connections and resets the pcu state so it can keep running. However, this never worked correctly which is why the -e option is used. This option exits the pcu as soon as the internal state needs to be reset.

This patch removes this option and makes this behaviour default.
