d401ad4233 wctc4xxp, wcte12xp, wctdm24xxp: Remove check for HAVE_NETDEV_PRIV
DAHDI currently supports kernels >= 2.6.9. netdev_priv() has been in the
mainline kernel since versions 2.6.6 so it's available in all the
supported kernels. This change is needed to compile against the 3.1 kernel.

9fd43e0139 wctc4xxp: Cleanup in-flight commands when halting due to hardware error.
On one system I was seeing the board reset in the middle of a
transaction. Any commands that were on the response list when this would
happen would never be completed and the process would then be stuck in
an uninterruptible sleep. This change also prevents the driver from
sleeping in timer context, which would result in a kernel panic.

This change at least lets an error message propogate back to the user.

1813c9ad09 wcb4xxp: Prevent null pointer dereference on spanconfig
In the rare case where spanconfig is called while there is pending data
on the hdlc channel, the hdlc_getbuf interrupt could try to read from
the hdlc buffer before the channel was fully setup. This could
potentially result in a null pointer dereference. This condition has
existed since the creation of the wcb4xxp driver.

00764f705c dahdi: Drivers that do not support hwec should not report hwec is available.
When attaching software echocans to a channel, if there is a hardware
echocan available always give preference to them.

Revision 9995 "dahdi: Always attach hwec to a channel if available" had
an error where if a driver did not even support an option of hardware
echocan, dahdi-base would take that to mean there always was a hardware
echocan available on the channel.

071cfdc983 wctdm24xxp, wcte12xp: Run the ISR with interrupts disabled.
Revision 9886, "wcte12xp: Use the in-hardirq versions of
dahdi_receive/dahdi_transmit", changed the call into dahdi_receive and
dahdi_transmit to use versions that assume local interrupts are already
disabled.  Not all versions of the kernel run interrupt service routines with
all interrupts disabled and therefore it was possible to lock up a CPU with a
recursive grab of the chan_lock.

When LOCKDEP was enabled (on debug kernels) interrupt handlers were run
atomically so this problem would only occur on pre 2.6.35 kernels that did not
have lockdep enabled.

64b150eb96 oct612x: Increase the size of some of the instance variables.
Revision 9750 "wct4xxp: Reduce the memory footprint of the hardware
echocanceler" reduced the number of bits used to store some structure
members. Some of the new field lengths were unable to store all the
possible values the API as used assigned to the fields, resulting in
channels never entering power down mode when they were disabled like
they were previously.

The change for byEchoOperationMode was found in testing the operation of
the VPMOCT032 which currently uses the same code. The others were done
via a review of the API doc.

This change represents negligable risk and contains no logic changes.
It only increases the memory footprint of the API instance in the
kernel.

bee7c5e579 wct4xxp: Add module parameter to ignore rotary switch settings.
The dual and quad span cards have a rotary switch onboard which controls
the order that cards serviced by this driver are registered with the
core of DAHDI. This commit adds a module parameter 'ignore_rotary'
which, when set to 1, causes the driver to ignore the position of the
rotary switch and only consider the physical slot when registering with
DAHDI.

Ignoring the rotary switch settings also permits the PCI device to be
bound and unbound from the driver at runtime since registration with
DAHDI no longer only happens when the module is first initialized.

By default, the rotary switch will still be used to determine
registration order. This commit does not change the default behavior.

59e277ef5a wctdm24xxp: Ensure battery drops on FXS hangups honor the channel otimer.
If an FXS port is configured to use kewl start signalling, when the FXS port
is "hungup" it should drop battery for 500ms so that any attached devices can
detect that the remote side has disconnected.  The wctdm24xxp driver
since version 2.4.0 was only dropping battery for ~5-10 ms because it would
set "open" on the line, but then the next time it read the line feed register
state, it was setting the LINE feed register to the idle state.

This change checks if the line is forced open before setting the FXS port back
"onhook" so as to not turn on battery prematurely.

This fixes a regression introduced in r9070 "wctdm24xxp: Prevent FXS Proslic
staying in "Forward/Reverse OnHookTransfer...". DAHDI-849.

Checking for open on the line feed registered was originally suggested by Alec
Davis.

f2c0bcd0f2 wcte12xp, wctdm24xxp: Load VPMOCT032 firmware in background.
The firmware load has been moved into a workqueue to prevent the module load
from blocking for the duration of the firmware upload. This could be up to 40
seconds. Driver prevents configuration until firmware load is finished and
is_initialized() returns true.

355ab14d47 dahdi: Always attach hwec to a channel if available.
In previous releases of DAHDI if dahdi_cfg attached a software echocan
to a channel and a hardware echocan was available, the hardware echocan
would be used instead of the software echocan.

Since the 2.4 branch was created a new feature was merged into
dahdi-linux where it was possible to mix software echocan and hardware
echocan on a channel. This required using "hwec" as the echocan in the
/etc/dahdi/system.conf file so that what was specified in the
configuration file is what was actually used.

This has resulted in users upgrading to the trunk of dahdi without
updating their /etc/dahdi/system.conf file and just suddenly not using
any hardware echocans any longer.

The capability to mix software and hardware echocans on a span will be
revisted when running dahdi_cfg on any preexisting configuration files
doesn't just silently turn off hardware echocan.

a36bd8863e Revert "dahdi: Group dahdi timers into "rates" for improved CPU utilization."
This reverts commit r9891 and is part of two commits to revert all the
timer changes.

Grouping the timer into rates did not allow a timers rate to be changed
after another thread is already blocked on the poll call

The problem that was reported was if a sip call was made to a DAHDI
channel and the sip call was disconnected before answer, the DAHDI
channel would never stop rining.

ab15df5810 kernel.h: Define __packed if not already defined.
Linux kernel v2.6.22 introduced the __packed macro to allow the gcc specific
__attribute__((packed)) extension to be overridden if required and
checkpatch.pl will complain if you don't use it.

For some strange reason gcc doesn't complain when you use non-existant
decorators.

a1d84ea99c wcte12xp: Start alarm timer after marking board initialized.
r9946, "wcte12xp: Move the VPMADT032 test/configuration to module load
time." introduced a race condition where it was possible for the timer
that initiates the check for the alarms to fire before the board was
marked initialized.  This would result in a board that would never again
check it's alarm state since the first time the timer runs INITIALIZED
may not be set and it will not reschedule a check since it believes the
driver is unloading.

This happened because the check for the VPM was moved between when the
timer was first setup and when INITIALIZED was then set.

Now we make sure INITIALIZED is set before the timer is first setup, and
move those two operations together.

90e504dc25 wctdm24xxp: Do not read extra register when test for FXO module fails.
In commit r9968 "wctdm24xxp: Allow more than one outstanding read at a
time" I introduced a regression where the transmit FIFO on the data
channel of a B400M could get locked up. The result would be constant
HDLC overflows when writing to the data channel.

This regression did not make it into any releases and did not exhibit
itself when crossing spans on a single B400M module. This is a partial
revert of commit r9968.

The board number dupliates the information that is available in the
location field. Exporting it as part of the description makes the name
