mISDN: Fix wrong usage of flush_work_sync while holding locks

2012-09-13T18:58:54+00:00

It is a bad idea to hold a spinlock and call flush_work_sync.
Move the workqueue cleanup outside the spinlock and use cancel_work_sync,
on closing the channel this seems to be the more correct function.
Remove the never used and constant return value of mISDN_freebchannel.

mISDN: Implement MISDN_CTRL_RX_OFF for more drivers

2012-05-16T19:24:36+00:00

MISDN_CTRL_RX_OFF is a meachanism to discard RX data in the driver if
the data is not needed by the application. It can be used when playing
mesages, but not recording or with unidirectional protocols.

mISDN: Implement MISDN_CTRL_FILL_EMPTY for more drivers

2012-05-16T19:24:05+00:00

MISDN_CTRL_FILL_EMPTY is a meachanism to send a fixed value (normally silence)
as long no data from upper layers is available. It can be used when recording
voice messages or with unidirectional protocols.

mISDN: Allow to set a minimum length for transparent data

2012-05-16T19:23:46+00:00

If the FIFO of the card is small, many short messages are queued up to
the upper layers and the userspace. This change allows the applications
to set a minimum datalen they want from the drivers.
Create a common control function to avoid code duplication in each
driver.

mISDN: Reduce RX buffer allocation for transparent data

2012-05-16T19:23:28+00:00

We did allways allocate maxsize buffers, but for transparent data we know
the actual size.
Use a common function to calculate size and detect overflows.

mISDN: Early confirm for transparent data

2012-05-16T19:22:29+00:00

It is better to send a confirm for transparent data early as possible
to avoid TX underuns.

mISDN: Make layer1 timer 3 value configurable

2012-05-04T15:55:05+00:00

For certification test it is very useful to change the layer1
timer3 value on runtime.

mISDN: Make clearing B-channel a common function

2009-07-25T18:18:16+00:00

Clearing B-channel is needed in every driver, so it makes sense
to have it as common function.

mISDN: Echo canceler now gets delay information from hardware

2009-05-25T07:51:31+00:00

Added tx-fifo information for calculation of current delay to sync tx and rx
streams for echo canceler.
