The eNBs drb.conf only has an entry for QCI 7 and 9. I think if the EPC
sends a invalid QCI it defaults to 7. But the should be an error logged.

So either change between 7 or 9, or add QCI 1 to the config.

Regarding the deletion of the UE entry: Make sure to exit srsEPC before
editing the CSV. The EPC saves the current context to the file so you're
changes get overridden if you do them while having the EPC running.

If the CSV is empty, no UE can attach.
