bts: Test if BTS forwards ETWS Primary Notification to PCU
All MS/UE must be notified of ETWS Primary Notifiations. Depending on their state, the notification goes different paths: * CS dedicated mode: BSC sends it as L3 message over LAPDm / DCCH * CS/PS idle mode: BTS sends paging messages on PCH * PS TBF active: PCU send Packet Application Info This tests the last of the three methods by checking that a ETWS Primary Notification sent on RSL to the BTS is received by the PCU socket.
