Almost anywhere in the code we avoid committing rxon while performing

in the code we do not follow that rule. This patch fix that problem in
iwlagn_configure_filter().
Since we do not commit directly in iwl3945_configure_filter, we can
also do the same for agn, so I just remove iwlcore_commit_rxon()

We have seen several DMA races when we race against
stopping and starting the PCU. I suspect that when
we cannot stop the PCU we may hit some of these same
races so warn against them for now but only when
debugging (CONFIG_ATH_DEBUG) is enabled.
If you run into this warning and are a developer,
please fix the cause of the warning. The potential
here, although I cannot prove yet, is that the DMA
engine can be confused and start writing to a buffer
that was already DMA'd before and at least the kernel
assumes is not being accessed by hardware anymore.

Currently the skb->protocol field is used to setup various
offloading parameters on transmit for the correct protocol.
However, if vlan offloading is disabled or otherwise not used,
the protocol field will be ETH_P_8021Q, not the actual protocol.
This will cause the offloading to be not performed correctly,
even though the hardware is capable of looking inside vlan tags.
Instead, look inside the header if necessary to determine the
correct protocol type.
To some extent this fixes a regression from 2.6.36 because it
was previously not possible to disable vlan offloading and this

Currently, blinking LEDs can be awkward because it is not guaranteed that
all LEDs implement blinking. The trigger that wants it to blink then
needs to implement its own timer solution.
Rather than require that, add led_blink_set() API that triggers can use.
This function will attempt to use hw blinking, but if that fails
implements a timer for it. To stop blinking again, brightness_set() also
needs to be wrapped into API that will stop the software blink.
As a result of this, the timer trigger becomes a very trivial one, and
hopefully we can finally see triggers using blinking as well because it's
always easy to use.

Bit 22 of AR_WA should be set to fix the situation where chip reset
is asynchronous to clock of analog shift registers, such that when
reset is released, it could mess up the values of analog shift registers
and cause some hw issue on AR9280.
This bit is write only, but the driver does a read-modify-write
on AR_WA without setting bit 22 in ar9002_hw_configpcipowersave()
during radio disable. This causes surprise removal of hw. It can
never recover from this state and the hw will become usable only
after a power on/off cycle, and sometimes only during a cold reboot.
This issue can be triggered by doing frequent roaming with the
simple/test-roam script available from the wifi-test project [1]
when roaming between APs quickly. When roaming there is a is a high
possibility that the device being put into idle (radio disable) state
by mac80211 during AUTH->ASSOC. A device hardware reset would fail
and the kernel would output:

This is currently only reproducible with some HB92 (Half Mini-PCIE)
cards but the fix applies to all AR9280 cards. This patch fixes this
issue by setting bit 22 during radio disable.
This patch has fixes for all kernels that has ath9k.

This bug seems to be due to commit 27ae60f8f7 ("ipw2x00: replace
"ieee80211" with "libipw" where appropriate"), where Pavel did this:
- libipw_proc = proc_mkdir(DRV_NAME, init_net.proc_net);
+ libipw_proc = proc_mkdir("ieee80211", init_net.proc_net);
but then the cleanup was kept as
remove_proc_entry(DRV_NAME, init_net.proc_net);
in both places (both in the failure case and in the unload case). The
error string is also total crap, and says
"Unable to create " DRV_NAME " proc directory\n");
Even though it doesn't actually create a proc directory named DRV_NAME at all.
So that patch looks like total and utter crap to me. The commit message says
"Keep /proc/net/ieee80211 under the original name to avoid breaking user
interface."
but the thing is, it really didn't fix anything but that one create
thing. It needs to fix all the other cases too.

Commit 27ae60f8f7 ("ipw2x00: replace "ieee80211" with "libipw" where
appropriate") changed DRV_NAME to be "libipw", but didn't properly fix
up the places where it was used to specify the name for the /proc/net/
directory.
For backwards compatibility reasons, that directory name remained
"ieee80211", but due to the DRV_NAME change, the error case printouts
and the cleanup functions now used "libipw" instead. Which made it all
fail badly.
For example, on module unload as reported by Randy:
WARNING: at fs/proc/generic.c:816 remove_proc_entry+0x156/0x35e()
name 'libipw'
because it's trying to unregister a /proc directory that obviously
doesn't even exist.
Clean it all up to use DRV_PROCNAME for the actual /proc directory name.

This patch enables and disables the rx and tx bits in the MAC control reg
by using a single write operation.
This also solves a possible problem (spotted on SPEAr platforms) at 10Mbps
where two consecutive writes to a MAC control register can take more than
4 phy_clk cycles.

This happens because the netif_start_queue sets respective bit on the dev->_tx
array which is not yet allocated.
As far as I understand the code removing the netif_start_queue from __NS8390_init
is OK, since queue will be started later on device open. Plz, correct me if I'm wrong.

The DCB credits refill quantum _must_ be greater than half the max

are not attempted during a pause state. Additionally, the min IFG
must be set correctly for DCB mode. If a DMA operation is
requested unexpectedly during the pause state the HW data
store may be corrupted leading to a DMA hang. The DMA hang
requires a reset to correct. This fixes the HW configuration

driver. Also, the device driver counters are resetted during the
the down process, and the hardware aren't, causing some weird
numbers.

ath9k locks for starting RX but not for stopping RX. We could
potentially run into a situation where tried to stop RX
but immediately started RX. This allows for races on the
the RX engine deciding what buffer we last left off on
and could potentially cause ath9k to DMA into already
free'd memory or in the worst case at a later time to
already given memory to other drivers.
Fix this by locking stopping RX.

On a busy network, the macb driver could get stuck in the interrupt
handler, quickly triggering the watchdog, due to a confluence of
factors:
1. macb_poll re-enables interrupts unconditionally, even when it will
be called again because it exhausted its rx budget
2. macb_interrupt only disables interrupts after scheduling
macb_poll, but scheduling fails when macb_poll is already scheduled
because it didn't call napi_complete
3. macb_interrupt loops until the interrupt status register is clear,
which will never happen in this case if the driver doesn't disable
the RX interrupt
Since macb_interrupt runs in interrupt context, this effectively locks
up the machine, triggering the hardware watchdog.
This issue was readily reproducible on a flooded network with a
modified 2.6.27.48 kernel. The same problem appears to still be in the
2.6.36-rc8 driver code, so I am submitting this patch against that
version. I have not tested this version of the patch except to make
sure the kernel compiles.

Timing issues in microcode for some devices can cause a compressed BA to
be sent to the driver prior to returning any a-MPDU notification.
Traces show RTS-CTS is exchanged and then the timer fires which causes an
empty BA to be sent which acknowledges nothing. This results in a noisy
printk. Only print the message if the bitmap is non-zero.

Since aggregation is usually triggered by tx completion, a hardware
reset (because of beacon stuck, tx hang or baseband hang) can
significantly delay the transmission of the next AMPDU (until the next
tx completion event).
Fix this by rescheduling aggregation after such a reset.

The ath9k aggregation code was already checking the rate control probe flag
to prevent starting an aggregate frame with a sampling rate. What was missing
was closing an aggregate before adding a probing frame to it.
Without that, rate control cannot have precise control over probing, which
delays using faster rates when the channel conditions improve.

This updates the initvals for the AR9003 2.2 chipsets. The initvals
are the initial register values we use for our registers upon hardware
reset. This synchs up the initvals to match what our latest recommendation
from our systems engineering team.
The description of changes in this update:
Improves ability to support very strong Rx conditions.
Enhances DFS support for AP-mode.
Improves performance of Tx carrier leak calibration.
Adds support for Japan channel 14 Tx filtering requirements.
Improves Tx power accuracy.
Impact:
Update required to address degraded throughput at very short range.
Update required for AP-mode DFS certification.
Update required to comply to IEEE Tx carrier leak specification.
May not meet expected +/- 2 dB Tx power accuracy without update.
The most important fix here would be the TX carrier leakage required
to comply with IEEE 802.11 specifications. The group of changes have
been tested all together in one release.

"carl9170: fix async command buffer leak"
left off.
Similar to carl9170_reboot/carl9170_powersave, the
carl9170_async_regwrite* macros would leak the
temporary command buffer, if __carl9170_exec_cmd

This patch allows IBoE traffic to be encapsulated in 802.1Q tagged
VLAN frames. The VLAN tag is encoded in the GID and derived from it
by a simple computation.
The netdev notifier callback is modified to catch VLAN device
addition/removal and the port's GID table is updated to reflect the
change, so that for each netdevice there is an entry in the GID table.
When the port's GID table is exhausted, GID entries will not be added.
Only children of the main interfaces can add to the GID table; if a
VLAN interface is added on another VLAN interface (e.g. "vconfig add
eth2.6 8"), then that interfaces will not add an entry to the GID
table.
