Sparse caught several places where ioctl interface was incorrectly using user
memory. Fix all the ioctl cases for casting and __user annotation.

This preserves the semantics of the original driver (unclassified packets
are dropped), but does it in a clean way; and fixes crash when packet
is sent to offline device.

Current kernels have multi-queue support which can be used by
this device. This has the advantage that a single type of traffic
will not block other types.

Change how network device is setup:
* set pointer to device object so sysfs has eth0/device symlink
* set network device type
* eliminate all the compatiablity with older kernels.

The way network devices are reference counted does not include poking
around in the reference count itself. This breaks when the reference
count is changed to be a different type. Fix the driver to do the
proper function calls instead.

"status" is used as an index into the Adapter->PackInfo[] array, which
has NO_OF_QUEUES elements.
This code actually works OK. The SearchSfid() function always returns
a valid index or it returns NO_OF_QUEUES + 1. But it looks sloppy and
it makes the static checkers complain.

The error handling here is wrong. If psIntfAdapter were NULL then we
would have a NULL dereference in the debug output on the error path.
But this function is only called from usbbcm_device_probe() when
psIntfAdapter is non-NULL.
Since the check isn't needed and I removed it instead of fixing it.

The WIMAX_MAX_MTU macro is used in drivers/staging/bcm/CmHost.c like
this:
if (Adapter->PackInfo[uiSearchRuleIndex].uiMaxBucketSize < WIMAX_MAX_MTU * 8)
The multiplication by eight has precedence over the addition so the
macro needs parenthesis to work.

This marks up the code where sparse complains in most cases.
Most of the changes are in the ioctl handling code, which
gets __user annotations, finding one unchecked user access.
The rest is mostly about marking functions static when they
are only used in one file.

As a preparation for changing the default behaviour of llseek to no_llseek,
every file_operations structure should have a .llseek operation.
There are three new instances in staging now, which can all be changed
into no_llseek explicitly since the devices do not need to seek.
Add nonseekable_open where appropriate, to prevent pread/pwrite as well.

The Sprint 4G network uses a Wimax dongle with Beecem
chipset. The driver is typical of out of tree drivers, but
maybe useful for people, and the hardware is readily available.
Here is a staging ready version (i.e warts and all)
0. Started with Rel_5.2.7.3P1_USB from Sprint4GDeveloperPack-1.1
1. Consolidated files in staging
2. Remove Dos cr/lf
3. Remove unnecessary ioctl from usbbcm_fops
Applied patches that were in the developer pack, surprising
there were ones for 2.6.35 already.
This is compile tested only, see TODO for what still needs
to be done.
