When the driver begins to initialize a device it conducts a read/write
test on one of the framer registers. The driver ignores the result of
that test and results in much output spammed to the kernel logs for a
failed card since the driver doesn't then try to unbind from the device.
What was getting spammed:
wcte12xp 0000:03:01.0: Timeout in t1_getreg
wcte12xp 0000:03:01.0: Wrote '0' but read 'fffffffb'
Now abort the bind if the read / write test fails.

r10006 "wctdm24xxp: Add 'fastpick' module parameter." copied the
fast-off hook module parameter from the wctdm.c driver, but the setting
in that driver does not match the data sheet. The previous commit did
not actually change any of the significant bits in that register. Also,
that commit changed the timer, but did not disable the callibration
delay which is necessary for Type-II callerid.
The fastpickup option in the wctdm24xxp driver should now match the
fastpickup option in the wctdm driver.

before the master span received a packet, the older packet on the

HAVE_NET_DEVICE_OPS was defined in the mainline kernel in commit

have those fields defined.
Mainline commit e2270ea62ae4d7a removed the feature test macros, so

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.

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.

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.

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.

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.
