89f9f3ed2a Allow ARCH to be set to "x86". That's what it is in Linux 2.6.24 for
both i386 and x86_64.  When calculating TARGET for x86 platform, use
CONFIG_X86 and CONFIG_X86_64 rather than ARCH.

4d5de4b5a2 This patch adds iwpriv values for setting the
time in ms, or the number of beacons for the
beacon miss alarm.  If we haven't had a beacon
in this period, the alarm is sounded and 
action (i.e. roaming) is taken.

This patch changes the storage of the beacon
miss threshold to integral beacon count but 
corrects the previous intent.

The default beacon miss alarm is going to be
850ms which is half way between the two hard
coded limits that were there before.

The old hard coded limits assumed that the
beacon interval was 100ms and set the limit to
10 (1000ms) for software beacon miss timer 
and 7 for hardware beacon miss timer.

The new default is 850ms (the midpoint between
the two previous defaults).  This value is rounded
up to the next nearest beacon interval.

There is no upper bound on the beacon miss
threshold specified, since it may need to be
wildly inflated with 25ms beacon interval, or
wildly reduced with 1000ms beacon interval.

The minimum is still 2 beacons, regardless of
the beacon interval.

99b36fbd0f Fix section mismatch warning in forthcoming Linux 2.6.25
Section mismatch checker in the forthcoming Linux 2.6.25 complains about
ath_pci_drv_id and recommends to rename it.  Rename ath_pci_drv_id to
ath_pci_driver, which is consistent with other PCI drivers.

6fbbcf00a0 This patch makes some debug messages about
dropped frames a little more consistent and
fixes an issue in hardstart where I was being
too aggressive about requeing.

I thought the slab allocator would stop handing
out skbuff instances before the system was out
of free memory based upon some kind of limit on
the number of buffers, but this was nonsense.

Therefore, it is NOT a good idea to requeue
when skb allocation fails because this pretty
much basically means we are out of free memory.

Keeping the packets we do not have the RAM to
send and then stopping the transmit queue has
very bad side effects under low/zero memory 
conditions.  

Symptoms may include OOM killer and panics,
among other things.

It's better to drop tx packets when there's no
more RAM than to lock all the tx packets up
in the transmit queue.  Even if more skb
become freed up in the slab cache due to 
transmissions already in progress, evil things
still happen.

874abd03ab Reduce the maximum message length for node
messages from 1000 to 192 and drop the length
needed to display the [atomic] node count.

Slamming this much data on the stack can cause
stack overflows with 4k stacks quite easily,
especially when hard interrupts occur and 
extend a stack that is already almost full.

2411a87efc During reset_bss we were incrementing the ref
count of the new bss node.  The allocation 
function gives us a reference.  With this extra
reference, every invocation of reset_bss was
causing a leak of one node ~4kb every time the
interface was brought back up (or the BSS was reset
for other reasons).

This fixes ticket #1682.  I can run ifconfig down/up
cycle for a long time.  I'll run it overnight next
to be sure.

602be360fc Move the node reference up that pins the WDS peer
node in the node table.  The node reference was
being taken in any path where the wds node was found
and not just when the wds node was first added.

This would have caused wds nodes to get inflated
reference counts, and be leaked on bss reset when
nodes were flushed from the node tables.

dead14502d Fix a few more leaked node references when a
copy of the bss node is used to send a message
we need to make sure all code paths release
it when done.  This bug combined with repeated
auth failures would cause node references to 
grow with every failure.  Then, if you were 
taking down the interface and bringing it back
up you would leak one page (4kb) every time the
the node table was flushed on transition to UP.

8041aa65bc in ath_intr, we will need HW TSF value if we get
HAL_INT_RX, HAL_INT_RXPHY, or HAL_INT_SWBA.  In
such cases, we will collect the earliest hw tsf
sample we can get and this is passed into send_beacon
and the trigger processing helper functions.

This cuts the number of hardware TSF reads by a 
factor of three per interrupt.  We should be reading
the hardware TSF now once on interrupt entry, and 
once in the second part of trigger processing when
we correct for hardware TSF rollover.
