Subject: [PATCH 18/19] staging: wfx: trace acknowledges not linked to any stations

From: Jérôme Pouiller <>

Some resources are associated to the outgoing of the stations. To avoid
any resource leaks. It is important to understand why an acknowledge is
not associated to any station.

Add a trace for that purpose.
