Hello Jeff,
this patch changes causes the airo driver to not reset the card when a
temporary WEP key is set, when the IW_ENCODE_TEMP flag is used. This is
needed for xsupplicant as 802.1x, LEAP, etc. change WEP keys frequently
after authentication and resetting the card causes infinite
reauthentication.

This patch seem safe to apply for all cards as the bsd driver already do

2) RCU without refcnt should use __in_dev_get_rcu().
3) All others must hold RTNL and use __in_dev_get_rtnl().

Latest wireless extensions moved a field from netdev -> wireless_handlers.
The WE core will now printk a warning on every call to get_wireless_stats()
on a driver that still uses the old field. This patch fixes orinoco.

Now that we are compiling with -fno-strict-aliasing (this is the

This patch adds support for WE-19 to the HostAP driver. One of
the major change is the use of an explicit flag to tell if iwstat is
in dBm or not.

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.
Change PCI driver names of hostap_pci and hostap_plx to be equal to
their module names.

Remove inneeded system includes.
Most system includes are not needed. In particular, the hardware
backends don't need anything network related. Some includes have been
moved from local headers to the C files where they are actually used.
Includes that have to be in the local headers are no longer from the C
sources.

Update PCMCIA ID's.
Intel Pro/Wireless 2011 and 2011B have the same numeric ID, so use
strings instead.
Take all entries from *.conf for Orinoco, HostAP and linux-wlan-ng and
adds them with minimal changes (e.g. we don't need a revision string
after a string that identifies the chipset).
Add comments with card names to all numeric entries. Note: the comments
don't and cannot cover all cards, since the main reason of having
numeric IDs is to cover cards that are often rebranded.
