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.

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.

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.
