The variable "counter" is defined and incremented but never
used except if the driver is hand-compiled setting
VERBOSE > SHOW_ERROR_MESSAGES.
Move the definition and the increment to within the

Remove extraneous udelay's.
These are not required when triggering the device.

This patch creates a file airo.h containing prototypes of the global
functions in airo.c used by airo_cs.c .
If you got strange problems with either airo_cs devices or in any other
completely unrelated part of the kernel shortly or long after a airo_cs
device was detected by the kernel, this might have been caused by the
fact that caller and callee disagreed regarding the size of the first
argument to init_airo_card()...

fid is declared as a u32 (unsigned int), and then a few lines later, it is checked for a value < 0, which is clearly useless.
In the two locations this function is used, in one it is *explicitly* given a negative number, which would be ignored with the
current definition.

The latest kernel added a pretty ugly fix for the orinoco etherleak bug
which contains bogus skb->len checks already done by the caller and causes
copies of all odd sized frames (which are quite common)
While the skb->len check should be ripped out the other fix is harder to do
properly so I'm proposing for this the -mm tree only until next 2.6.x so
that it gets tested.
Instead of copying buffers around blindly this code implements a padding
aware version of the hermes buffer writing function which does padding as
the buffer is loaded and thus more cleanly and without bogus 1.5K copies.

The aironet PCI driver has a build dependency on ISA that prevent the
driver to compile on systems that doesn't support ISA, like x86_64. The
driver really doesn't depend on ISA, it does some ISA stuff in the
initialization code, since the driver supports both ISA and PCI cards. So
the driver should depend on ISA_DMA_API to build on all systems, and this
will not hurt PCI at all.

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

driver operations when ejecting a Prism2 PC Card. Anyway, should there
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.

The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
introduces __in_dev_get_rcu() to cover the second case.
1) RCU with refcnt should use in_dev_get().
2) RCU without refcnt should use __in_dev_get_rcu().
3) All others must hold RTNL and use __in_dev_get_rtnl().
There is one exception in net/ipv4/route.c which is in fact a pre-existing
race condition. I've marked it as such so that we remember to fix it.
This patch is based on suggestions and prior work by Suzanne Wood and
Paul McKenney.

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.
