[PATCHv5 13/18] Bluetooth: Flag ACL frames as complete for AMP controllers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



AMP controllers expect to transmit only "complete" ACL frames.  These
frames have both the "start" and "cont" bits set.  AMP does not allow
fragmented ACLs.
