Since r5021 [1], first released in DAHDI-Linux 2.2.0, it's been impossible for
user space to change the rxbufpolicy. This hasn't caused any problems and it's
safe to remove a few more of the vestiges of the rxbufpolicy from the driver.
This streamlines the code path in a few places and saves 8 bytes from the size
of struct dahdi_chan.
The user visible parts are maintained and will indicate
DAHDI_POLICY_IMMEDIATE, like it has since 2.2.0.

Since r10683 "convert span->spantype to enumerated type" [1] the spantype was
changed from a string provided by the board drivers to an enumerated type that
is handled by the core of DAHDI. This was done to simplify the task of
dahdi_genconf since there is only one place to look for the valid strings that
can be exported in sysfs.
This eliminates the following warning on driver load:
Warning: Span %s didn't specify a spantype. Please fix driver!

Internally in DAHDI there is always a hardware echocan factory registered and
available. Having this factory always registered allows for DAHDI to work in a
backward compatible fashion. Namely, by default DAHDI will always use a hardware
echocan if one is available unless 'hwec_overrides_swec' dahdi module parameter
is set to 0 on load. However, if there were no real hardware echocans available
in the system dahdi would still report "Echo Canceller(s): HWEC" in the
dahdi_cfg -v output since the hwec factory is always there.
After this change dahdi_cfg will no longer report HWEC as one of the available
echocans if there isn't a physical span present that actually has a hardware
echocan.

When DAHDI is bridging channels between two different cards, or a user is trying
to record from a channel on a card that is not using the same timing source as
the master span, it is possible to miss audio.
For example, given the following scenario:
<T1 Span> <---> <ISDN CARD> <---> <ANALOG CARD> <---> <local handset>
If DAHDI was set to natively bridge the call from the T1 span to the local
handset it is possible that system conditions could result in one of the cards
servicing their interrupt three times before the other card has a chance to.
Since there are currently only two conference buffers to pass audio between the
cards, one chunk (1ms) of audio will be dropped since the card servicing it's
interrupt more frequently will run out of space to copy audio for the other card
and will have emptied the audio buffer from the other card.
Increasing the number of conference buffers to eight greatly reduces the
probability of audio from being dropped under these conditions at cost of an
additional 72 (32-bit) or 96 (64-bit) bytes per DAHDI channel.

This fixes a regression introduced in commit r10186 "wctdm24xxp: Use time
interval for debouncing FXO ring detect." [1] which was first released in
DAHDI-Linux 2.6.0. This only affects users with analog trunks whose providers do
not present 4 polarity reversals on the ring signals. The reporter of this issue
is based in South Africa.
[1] http://svnview.digium.com/svn/dahdi?view=revision&revision=10168
In prior versions, the ring detector did not check for polarity reversals, only
the presence of ringing voltage unless fwringdetect or neonmwi_monitor mode was
set, and even when one of those modes were set, the driver only needed two
reversals to validate a ring. This commit allows the driver to always stay in
fwringdetect mode but restores the requirement for only two reversals.
Also included in this commit is a change to ensure that ringing is not reported
when debouncing lost battery which can happen when voltage is swinging through
0.

The frequency that the RBS registers were polled was too slow to catch the pulse
dialing digits. The result was that often times dahdi would generate WINK events
instead of PULSEDIGIT events.
This speeds up the rate at which the registers are checked from 100ms to 33ms
and also makes the process of checking the registers quicker by queing up all
the reads at once.

This is a port of the functionality in the wctdm24xxp driver to support power
savings modes. Specifically, if the the network side of a BRI spans deactivates
the span to save power, the B410P previously automatically activated it again.
Now, if persistentlayer1=0 module parameter is set, the span will be allowed to
stay deactivated until layer two has a message to send on the dchannel.
This patch does not change any of the default behavior of the B410P driver and
the defaults for the persistentlayer1 option is inconsistent with that of the
B400M modules in the wctdm24xxp driver.

It appears that some kernel configurations do not include timer.h in any of
the include files that are included by dahdi_dummy. The timer_structs are
defined in timer.h and not time.h, so this change is correct even though I

Also closes anoter potential kernel oops on module unload. It was possible to
delete the private structure while the master span process was running. The

The board drivers are the ones calling the unregister function, and
therefore we do not need to worry about them unloading while calling the
destroy callback.
When destroying spans with the ioctl, replace __module_get() with
try_module_get. This avoids hitting a BUG in module_get on kernel versions <
2.6.29.
ALSO move the call to try_module_get out of the dahdi_dynamic_release function
and into destroy. This way if the destroy callback isn't called because the
dynamic driver is unloading the dynamic device can be left on the list to be
cleaned up by the dahdi_dynamic_unregister_driver function().

structure that contains the owner as well as the ioctl callback. This way
dahdi.ko can bump up the reference count on dahdi_dynamic.ko before calling

between the time the structure pointer was checked, and the module reference
is taken.

This is a partial revert of r10234 "wct4xxp: __t4_framer_in and
__t4_framer_out speedups."
There were some platform + firmware version combinations that would fail to
properly configure the framer with the aforementioned speedups. The originally
reported sympton was that interrupts would fail to start and while
troubleshooting I also saw cases where one of the spans would stay in alarm
after starting. By adding in additional reads to the version register, the
overall process of writing / reading from the framer control registers is
slowed down which increases reliability.
This change does *not* affect the main path of TDM data which is DMAed
directly into buffers in host memory and are not read / written to / from
framer registers directly.
