Subject: [PATCH 1/3] Bluetooth: Use only 2 bits for controller type information
Date: Sun, 29 Sep 2013 21:10:59 -0700 [thread overview]
Message-ID: <1380514261-21742-1-git-send-email-marcel@holtmann.org> (raw)
The controller type is limited to BR/EDR/LE and AMP controllers. This
can be easily encoded with just 2 bits and still leave enough room
for future controller types.
