Subject: [PATCH] Bluetooth: L2CAP connectionless channels are only valid for BR/EDR
Date: Thu,  3 Oct 2013 00:03:39 -0700	[thread overview]
Message-ID: <1380783819-47726-1-git-send-email-marcel@holtmann.org> (raw)

When receiving connectionless packets on a LE connection, just drop
the packet. There is no concept of connectionless channels for LE.
