gcc 4.5.0 was generating a warning on the changed line, and the
discussion at http://gcc.gnu.org/ml/gcc/2004-10/msg00024.html explains
why.
Essentially, the only thing guaranteed with the preincrement operator is
that the value will be incremented before the assignment. It's
undefined where in the sequence the mask will be applied.

Some versions of the kernel (2.6.18-92.1.22.el5) have patches in them to panic
if a slab cache is created with unsupported flags.

Polling the driver increases overall system throughput when there are several
transcoding channels open by reducing the number of interrupts the the TC400M
generates.

It is possible for system activity to prevent the wctc4xxp driver from
responding the the firmware on the TC400M for a period of time. If this occurs,
the TC400M will resend a response to a command that we sent. This duplicate
reponse will then sometimes confuse the driver. Normally this would manifest
as an attempt to connect the same channel together in a transcoding session.

This change is to catch a condition where it is possible, for whatever reason,
for a response to come in before the request is marked tx complete.
If this happened, it was possible to leak the response packet and double complete
the command.

Trivial change that makes the code read more naturally. Also changes the order
of members in the channel_pvt structure. For more natural alignment. Both
non-functional changes.

pressure on the stack, and brings driver closer to kernel coding standards.

encoder and decoder arrays, and not the channel which is returned from the
DTE. Issue: DAHDI-231.
- Instead of completely servicing the receive descriptor ring in the
workqueue, have the interrupt handler queue them up for the workqueue.
- No need to interrupt on both transmit and receive since we expect a
response to every packet we send.

the probability of running out of receive descriptors.

- When a command is to be retried, turn off the TX_COMPLETE flag before
resubmitting it to the hardware. This should elimate some of the warnings
printed to the kernel log in the wctc4xxp_transmit_cmd function.
