Subject: Bluetooth: Flag ACL frames as complete for AMP controllers
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d5f8a75d88ecef3987158a94e8070bdfb46b09bd;p=deliverable%2Flinux.git

Bluetooth: Flag ACL frames as complete for AMP controllers

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.
