Bluetooth: Free the l2cap channel list only when refcount is zero

2012-08-06T18:02:58+00:00

Move the l2cap channel list chan->global_l under the refcnt
protection and free it based on the refcnt.

Bluetooth: Move l2cap_chan_hold/put to l2cap_core.c

2012-08-06T18:02:58+00:00

Refactor the code in order to use the l2cap_chan_destroy()
from l2cap_chan_put() under the refcnt protection.

Bluetooth: Use tx window from config response for ack timing

2012-07-15T15:18:29+00:00

This change addresses an L2CAP ERTM throughput problem when a remote
device does not fully utilize the available transmit window.

The L2CAP ERTM transmit window size determines the maximum number of
unacked frames that may be outstanding at any time. It is configured
separately for each direction of an ERTM connection. Each side sends a
configuration request with a tx_win field indicating how many unacked
frames it is capable of receiving before sending an ack. The
configuration response's tx_win field shows how many frames the
transmitter will actually send before waiting for an ack.

It's important to trace both the actual transmit window (to check for
validity of incoming frames) and the number of frames that the
transmitter will send before waiting (to send acks at the appropriate
time). Now there are separate tx_win and ack_win values. ack_win is
updated based on configuration responses, and is used to determine
when acks are sent.

Bluetooth: Create empty l2cap ops function

2012-06-05T03:34:16+00:00

A2MP doesn't use part of the L2CAP chan ops API so we just create general
empty function instead of the A2MP specific one.

Bluetooth: Rename L2CAP_LE_DEFAULT_MTU

2012-06-05T03:34:16+00:00

This patch renames L2CAP_LE_DEFAULT_MTU macro to L2CAP_LE_MIN_MTU
since it represents the minimum MTU value, not the default MTU
value for LE.
