This patch makes sure that settings which are specific for BR/EDR capable adapters are not allowed for non-BR/EDR (e.g. LE-only) adapters.

2012-10-24Bluetooth: Start channel move when socket option is changedMat Martineau2-0/+24
Channel moves are triggered by changes to the BT_CHANNEL_POLICY sockopt when an ERTM or streaming-mode channel is connected. Moves are only started if enable_hs is true.

2012-10-24Bluetooth: Do not retransmit data during a channel moveMat Martineau1-2/+2
Do not retransmit previously-sent data when a "receiver ready" s-frame with the "final" flag is received during a move. The ERTM state machines will resynchronize at the end of a channel move, and the state machine needs to avoid state changes during a move.

2012-10-24Bluetooth: Ignore BR/EDR packet size constraints when fragmenting for AMPMat Martineau1-1/+3
When operating over BR/EDR, ERTM accounts for the maximum over-the-air packet size when setting the PDU size. AMP controllers do not use the same over-the-air packets, so the PDU size should only be based on the HCI MTU of the AMP controller.

2012-10-24Bluetooth: Configure appropriate timeouts for AMP controllersMat Martineau1-6/+41
The L2CAP spec recommends specific retransmit and monitor timeouts for ERTM channels that are on AMP controllers. These timeouts are calculated from the AMP controller's best effort flush timeout. BR/EDR controllers use the default retransmit and monitor timeouts.

2012-10-24Bluetooth: Do not send data during channel moveMat Martineau1-0/+12
Outgoing ERTM data is queued during a channel move. The ERTM state machine is partially reset at the start of a move, and must be resynchronized with the remote state machine at the end of the move. Data is not sent so that there are no state transitions between the partial reset and the resync. Streaming mode frames are dropped during a move.

2012-10-24Bluetooth: Flag ACL frames as complete for AMP controllersMat Martineau1-0/+9
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.

2012-10-24Bluetooth: Handle physical link completionMat Martineau1-0/+164
Several different actions may be taken when an AMP physical link becomes available. A channel being created on an AMP controller must continue the connection process. A channel being moved needs to either send a move request or a move response. A failed physical link will revert to using a BR/EDR controller if possible.

2012-10-24Bluetooth: Add logical link confirmMat Martineau1-11/+123
The logical link confirm callback is executed when the AMP controller completes its logical link setup. During a channel move, a newly formed logical link allows a move responder to send a move channel response. A move initiator will send a move channel confirm. A failed logical link will end the channel move and send an appropriate response or confirm command indicating a failure. If the channel is being created on an AMP controller, L2CAP configuration is completed after the logical link is set up.

2012-10-24Bluetooth: Move channel responseMat Martineau1-15/+168
The move response command includes a result code indicating "pending", "success", or "failure" status. A pending result is received when the remote address is still setting up a physical link, and will be followed by success or failure. On success, logical link setup will proceed. On failure, the move is stopped. The receiver of a move channel response must always follow up by sending a move channel confirm command.

2012-10-24Bluetooth: Add state to hci_chanMat Martineau1-0/+1
On an AMP controller, hci_chan maps to a logical link. When a channel is being moved, the logical link may or may not be connected already. The hci_chan->state is used to determine the existance of a useable logical link so the link can be either used or requested.

2012-10-24Bluetooth: Add move channel confirm handlingMat Martineau1-3/+55
After sending a move channel response, a move responder waits for a move channel confirm command. If the received command has a "confirmed" result the move is proceeding, and "unconfirmed" means the move has failed and the channel will not change controllers.

2012-10-24Bluetooth: Add new ERTM receive states for channel moveMat Martineau1-0/+102
Two new states are required to implement channel moves with the ERTM receive state machine. The "WAIT_P" state is used by a move responder to wait for a "poll" flag after a move is completed (success or failure). "WAIT_F" is similarly used by a move initiator to wait for a "final" flag when the move is completing. In either state, the reqseq value in the poll/final frame tells the state machine exactly which frame should be expected next.

2012-10-24Bluetooth: Channel move request handlingMat Martineau1-1/+112
On receipt of a channel move request, the request must be validated based on the L2CAP mode, connection state, and controller capabilities. ERTM channels must have their state machines cleared and transmission paused while the channel move takes place. If the channel is being moved to an AMP controller then an AMP physical link must be prepared. Moving the channel back to BR/EDR proceeds immediately.
