I wanted to remove the #include "hostap_ioctl.c" from hostap.c and
build hostap_ioctl.c separately, but this doesn't work since hostap.c
has the same name as the module.

After renaming hostap.c this will be possible.

This patch removes almost all inclusions of linux/version.h.  The 3
#defines are unused in most of the touched files.

A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.

There are also lots of #ifdef for long obsolete kernels, this was not
touched.  In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

Unregister all netdevs before freeing local data. I was unable to

be a race condition with this, better make it less likely to happen by
unregistering the netdevs first.

local->hw_priv was being freed and set to NULL just before calling
prism2_free_local_data(). However, this may expose a race condition in
which something ends up trying to use hw_priv during shutdown. I
haven't noticed this happening, but better be safe than sorry, so
let's postpone hw_priv freeing to happen only after
prism2_free_local_data() has returned.

Host AP driver used hardware model specific dev_open/close handlers
that were called on dev_open/close if the hardware driver had
registered the handler. These were only used for hostap_cs and only
for tracking whether any of the netdevs were UP. This information is
already available from local->num_dev_open, so there is not need for
the special open/close handler.

Let's get rid of these handlers. In addition to cleaning up the code,
this fixes a module refcounting issue for hostap_cs where ejecting the
card while any of the netdevs were open did not decrement refcount
properly.

hostap_pci and hostap_plx drivers still use PCI driver names
"prism2_pci" and "prism2_plx" respectively.  This is unfriendly to
linux-wlan-ng, which uses the same names.  So, if e.g. hostap_pci and
prism2_pci are loaded, they will "share" /sys/bus/pci/drivers/prism2_plx
directory.

PCI version of Prism2.5/3 has undocumented DMA support for TX/RX data,
but this seems to have some hardware bugs that prevent it from being
used properly for TX. RX side could possibly be made to work reliably.

Even though DMA support would be very useful for saving host CPU (from
about 40% to 5-10% when operating at maximum throughput), it seems to
be best to just remove this code finally. The implementation has
always been commented out by default and has received very limited
testing. The code may have already been broken number of times and I
don't have much interested in trying to verify whether it works or
not. Getting this out makes it easier to maintain the driver and
allows some cleanups that have been partly postponed because of this
experimental bus master/DMA code.

Old AP mode code for power saving was using skb->cb for couple of
flags before the more generic 802.11 TX code started using the same
buffer for struct hostap_skb_tx_data. This resulted in the power save
code corrupting the magic value in beginning of the buffer and TX code
dropping the power saved packets because of this for the case where
STAs send PS-Poll frames with PwrMgmt flag set.

This patch modifies the power save code to use the same struct
hostap_skb_tx_data as rest of the TX path in order to avoid corrupting
the data in skb->cb.

In addition, this patch reorders fields in the structure and makes
them use smaller types in order to make the structure fit in skb->cb
on 64-bit hosts.

Warning fix for 64-bit platforms

Hello!

The patch fixes following warning seen on 64-bit platforms (in my case -
x86_64, gcc-4.0):

In file included from /usr/local/src/hostap/driver/modules/hostap_cs.c:203:
/usr/local/src/hostap/driver/modules/hostap_hw.c: In function ?prism2_transmit_cb?:
/usr/local/src/hostap/driver/modules/hostap_hw.c:1674: warning: cast from pointer to integer of different size
/usr/local/src/hostap/driver/modules/hostap_hw.c: In function ?prism2_transmit?:
/usr/local/src/hostap/driver/modules/hostap_hw.c:1758: warning: cast to pointer from integer of different size

prism2_transmit_cb uses a (void *) argument to get an integer.   A
simple fix would be to use double cast from pointer to long and then to
int (and vice versa when int is passed as a pointer).  But I prefer a
slightly longer patch.

I believe that whenever an argument can hold both a pointer and an
integer, it should be declared long.  long can hold both pointers and
integers (except win64, but we are not coding for Windows), it can be
cast to both of them and it's never assumed to be a valid pointer, which
could be useful for some automatic code checkers.
