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.

Replace remaining WLAN_FC_* defines with the ones used in ieee80211
header file. This completes the move from hostap version of frame

Replace Host AP version of WEP, TKIP, CCMP implementation with
net/ieee80211 that has more or less identical implementation (since
it is based on the Host AP implementation). Remove Host AP specific
implementation and modules from drivers/net/wireless/hostap.

Preparations for starting to use net/ieee80211 instead of private
IEEE 802.11 implementation. Include net/ieee80211.h and
net/ieee80211_crypt.h into files that will be needed these in the
future. Remove duplicate definitions from hostap_common.h and
rename WLAN_FC_GET_{TYPE,STYPE} macros for now sinc net/ieee80211.h
is using incompatible definitions. This will be resolved in the
future by updating Host AP to use the versions that do not shift
type/stype.

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.
