Subject: Bluetooth: Provide defaults for LE connection latency and timeout
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=04fb7d9066dd9173ef0d4ccea8fe3bb59bd94605;p=deliverable%2Flinux.git

Bluetooth: Provide defaults for LE connection latency and timeout

Store the connection latency and supervision timeout default values
with all the other controller defaults. And when needed use them
for new connections.
