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: Add E-Channel logging features

2009-01-09T21:44:25+00:00

New prim PH_DATA_E_IND.

 - all E-ch frames are indicated by recv_Echannel(), which pushes E-Channel
   frames into dch's rqueue
 - if dchannel is opened with channel nr 0, no E-Channel logging
   is requested
 - if dchannel is opened with channel nr 1, E-Channel logging
   is requested. if layer1 does not support that, -EINVAL
   in return is appropriate

mISDN: Add feature via MISDN_CTRL_FILL_EMPTY to fill fifo if empty

2009-01-09T21:44:22+00:00

This prevents underrun of fifo when filled and in case of an underrun it
prevents subsequent underruns due to jitter.
Improve dsp, so buffers are kept filled with a certain delay, so moderate
jitter will not cause underrun all the time -> the audio quality is highly
improved. tones are not interrupted by gaps anymore, except when CPU is
stalling or in high load.
