[PATCH 4/4] ath10k: fix fw stats processing
Michal Kazior

Thu Sep 25 03:33:50 PDT 2014
If stat data exceeds wmi-htc buffer limits
firmware splits it into many wmi stats update
events which are delivered in a ping-pong fashion
triggered by wmi stats request command.
Since there's only an implicit start-of-data and
no end-of-data indications the driver has to
perform some trickery to get complete stat data.
