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.

line 129 of hostap_80211_rx.c should read:

not:

The length field is incorrect.

Firmware seems to be getting into odd state in host_roaming mode 2
when hostscan is used without join command, so try to fix this by
re-joining the current AP. This does not actually trigger a new
association if the current AP is still in the scan results.

This makes background scans (iwlist wlan0 scan) not to break data
connection when in host_roaming 2 mode, e.g., when using wpa_supplicant.

Cleaned up scan result processing by converting struct
hfa384x_scan_result into struct hfa384x_hostscan_result. This removes
special cases from result processing since the results are only used
in one, hostscan, format.

pcmcia id_table for hostap_cs.c

Hi Jouni,

Here's a patch for adding a pcmcia id_table to hostap_cs.c as introduced
by the PCMCIA subsystem changes in linux-2.6.13-rc1. The id_table allows
hotplug (along with pcmciautils [1]) to load the driver without the need
for the pcmcia-cs cardmgr daemon.

The id_table was generated from the CVS version of hostap_cs.conf using
a script borrowed from Dominik Brodowski. I have removed any duplicate
entries, but I have only been able to test the functionality of the
patch with a Linksys WPC11v3.

Sincerely,
Brix

Create sysfs "device" files for hostap

I was writing some scripts to automatically build kismet source lines,
and I noticed that hostap devices don't have device files, unlike my
prism54 and ipw2200 cards:

$ ls -l /sys/class/net/eth0/device
/sys/class/net/eth0/device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:02:01.0
$ ls -l /sys/class/net/wifi0
ls: /sys/class/net/wifi0/device: No such file or directory
$ ls -l /sys/class/net/wlan0
ls: /sys/class/net/wlan0/device: No such file or directory

The following (quite small) patch makes sure that both the wlan and wifi
net devices have that pointer to the bus device.

This way, I can do things like

        for i in /sys/class/net/*; do
                if ! [ -e $i/device/drive ]; then
                        continue;
                fi;
                driver=$(basename $(readlink $i/device/driver))
                case $driver in
                        hostap*)
                                echo -- hostap,$i,$i-$driver
                                break;
                        ipw2?00)
                                echo -- $driver,$i,$i-$driver
                                break;
                        prism54)
                                echo prism54g,$i
                esac
        done

Which should generate a working set of source lines for kismet no matter
what order I plug the cards in.

It might also be handy to have a link between the two net devices, but
that's a patch for another day.

That patch is against 2.6.13-rc1-mm1.
