MFC'ed i due time. I can't test it under current right now because netgraph seems to do unethical things with mutexes. musycc: Add status per channel. Reduce printf chattyness Keep error counters line if_mn does. Increase descriptor count. if_mn: Support experimental unframed E1 lines. These two drivers should share more code relating to framed channelized TDM media in general (T1/E1/E3/T3, Sonet). Anyone interested email me.

|
* Driver for Siemens reference design card "Easy321-R1".
|
|
*
|
|
* This card contains a FALC54 E1/T1 framer and a MUNICH32X 32-channel HDLC
|
|
* controller.
|
|
*
|
|
* The driver supports E1 mode with up to 31 channels. We send CRC4 but don't
|
|
* check it coming in.
|
|
*
|
|
* The FALC54 and MUNICH32X have far too many registers and weird modes for
|
|
* comfort, so I have not bothered typing it all into a "fooreg.h" file,
|
|
* you will (badly!) need the documentation anyway if you want to mess with
|
|
* this gadget.
