From fec1a5932f16c0eb1b3f5ca2e18d81d860924088 Mon Sep 17 00:00:00 2001 From: Stefano Panella Date: Tue, 4 Nov 2008 15:39:08 +0000 Subject: uwb: per-radio controller event thread and beacon cache Use an event thread per-radio controller so processing events from one radio controller doesn't delay another. A radio controller shouldn't have information on devices seen by a different radio controller (they may be on different channels) so make the beacon cache per-radio controller.
