xpp r5151:
* xpd_pri: Basically ready.
* PCM synchronization changes:
- Each Astribank unit ticks independently. Each with its own PLL.
- HOST synchronization is gone. Loading of xpp will no longer cause
useless 250 ticks per second if you have no Astribank.
- Synchronization from the zaptel sync master requires setting
ZAPTEL as sync source (xpp_sync ZAPTEL).
* rx_tasklet is now a parameter of the module xpp, rather than of xpp_usb.
* New FPGA firmware: 5128 (1151) / 5122 (1141, 1131):
- Fixes synchronization issues.
- PRI module: E1 should now work.
* perl module and utilities:
- Modules no longer magically scan system on initialization.
- Scanning is by calling explicit methods.
- "Serial" has been renamed "Label". It is basically unique, but
should be modifieble.
- Some basic documentation of zaptel perl modules.
* Default sort order of zt_registration is back to SORT_CONNCTOR.
* zt_registration proc file now shows the number of span registered to
if registered. Try: grep . /proc/xpp/XBUS-*/XPD-*/zt_registration
* genzaptelconf: Allow using a custom command instead of
/etc/init.d/asterisk to start/stop asterisk.
* Fixed the typo "Slagish".
