Bluetooth: Pause RFCOMM TX when encryption drops
A role switch with devices following the Bluetooth pre-2.1 standards or without Encryption Pause and Resume support is not possible if encryption is enabled. Most newer headsets require the role switch, but also require that the connection is encrypted. For connections with a high security mode setting, the link will be immediately dropped. When the connection uses medium security mode setting, then a grace period is introduced where the TX is halted and the remote device gets a change to re-enable encryption after the role switch. If not re-enabled the link will be dropped. Based on initial work by Ville Tervo <ville.tervo@nokia.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
