xpp rev. 3814:

  * Protocol no. 2.6: syncing improvements.
  * Support for 8-port Astribank BRI.
  * Firmware unloading now works:
    rmmod xpp_usb; /etc/hotplug/usb/xpp_fxloader reset
  * Defaults of kernel parameters are now part of parameter description.
  * World-readable kernel parameters.
  * No need for extra patch beyond bristuff for Astribank BRI.
  * Default poll intervals changed: 500 in BRI and FXO.
  * Allow changing FXS polls interval at run time.
  * BRI initalization fixed on SUSE (path to logger).
  * When using the SUSE zaptel rpm package, set modules_var=ZAPTEL_MODULES in
    /etc/sysconfig/zaptel .
  * zt_registration not verbose by default.
  * xpp_sync warns if FXO is sync slave.
  * Fixed genzaptelconf -z (zapscan output emulation).
  * PCM fixes.
  * Solves "multiple ticks" bug. No need for pcm_tasklets workaround.
