From 5d4e7e8db0544ec53025383bac49a3328affdad3 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Fri, 13 Sep 2013 11:40:01 +0300 Subject: Bluetooth: Add synchronization train parameters reading support This patch adds support for reading the synchronization train parameters for controllers that support the feature. Since the feature is detectable through the local features page 2, which is retreived only in stage 3 of the HCI init sequence, there is no other option than to add a fourth stage to the init sequence. For now the patch doesn't yet add storing of the parameters, but it is nevertheless convenient to have around to see what kind of parameters various controllers use by default (analyzable e.g. with the btmon user space tool).
