This rewrites the error handling policies in the TX status handler.
It tries to be error-tolerant as in "try hard to not crash the machine".
It won't recover from errors (that are bugs in the firmware or driver),
because that's impossible. However, it will return a more or less useful
error message and bail out. It also tries hard to use rate-limited messages
to not flood the syslog in case of a failure.

But bonding driver set netdev->dev_addr field to its original value,

When ever active slave changes, it swap dev_addr of inactive slave with active.
Yet it doesn't notify driver about change in netdev->dev_addr.
As netxen driver need to set mac addr when ever interface comes up,

The Tx unit hang detection code in e1000e detects other hangs caused by
hardware components (e.g. Rx, DMA units), but it is not possible to detect
exactly which component is hung so it has always assumed a Tx unit hang.
When dumping a message to the system log because of a hang, this patch adds
more data to help narrow the cause of the issue and makes the message
non-Tx-specific. Because this new code reads PHY registers which can
sleep, move it off to a workqueue. This and all previously existing work
tasks in the driver are now cancelled when the driver is removed.

The driver was only updating MII stats when an LSC up was detected and
the interface had not already been reported up to netdev. This meant
MII stats returned in response to an SIOCGMIIREG ioctl would always
show a link up if it had ever been up. This was misleading the networking
daemon guessnet, which uses this ioctl, into making improper network port
selections.
This fix adds a call to e1000_phy_read_status() to actively read the

Copper links with WoL or management enabled (any condition which prevents
the phy from being powered down when the interface is taken down) were
always reporting link-up when the interface had been taken down. This
is because when the interface is taken down (ifconfig ethx down),
interrupts are disabled. With no interrupts, there is no LSC interrupt,
which is normally required to set "get_link_status", which instructs the
driver to query the device for link state. The fix is to force
get_link_status to true if the interface is not up.

-Remove to read 4 extra bytes from the receiving queue after reading a

-Remove occurrences of transmission done interrupt in order to tx

-Enable IP checksum for packet receiving by setting the corresponding

-Relocate ks_enable_int()/ks_disable_int() in order not to declare those

Right now all frames mac80211 hands to the driver
have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set to
request TX status. This isn't really necessary, only
the injected frames need TX status (the latter for
hostapd) so move setting this flag.
The rate control algorithms also need TX status, but
they don't require it.
Also, rt2x00 uses that bit for its own purposes and
seems to require it being set for all frames, but
that can be fixed in rt2x00.
This doesn't really change anything for any drivers
but in the future drivers using hw-rate control may
opt to not report TX status for frames that don't
have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set.

Those constraints are:
- The address limitations on 30/32bit engines, that also apply to

- The 4k alignment requirement on 30/32bit engines.

According to IEEE80211 standard all the data packets have to be sent with
TODS bit set. This patch fixes the null data packet format which was sent
without TODS bit set. This should fix many problems associated with
power save. Janne Ylalehto also found this fix in the same time as mine,
for a different bug he was working on.

This patch increases the number of beacons to be missed before generating

Earlier firmware was stored to a memory area allocated with kmalloc()
but finding a a contiguous area of memory long enough for the firmware is

Implement (slightly) delayed entry into ELP. This will cure several
problems:
- It works around a firmware race condition if ELP is entered too fast
after commands (resulting in ELP timeout -traces)
- It will reduce the number of sleep-wake cycles between already
scheduled events such as interrupts and tx, hence improving
performance (less delay in switching between RX and TX)

At least two revisions of the D-Link DWA 160 exist, called A1 and A2. A1
(USB-ID 07d1:3c10) is already listed in usb.c as D-Link DWA 160A. A2
(USB-ID 07d1:3a09) works if added to ar9170_usb_ids. I didn't do much
testing until now, but I was able to connect to APs using WPA or WEP and
transmit data.
Summary:

* Add support for D-Link DWA 160 A2 (07d1:3a09)

Using the new mac80211 functionality, this makes
iwlwifi handle unicast PS buffering correctly.
The device works like this:
* when a station goes to sleep, the microcode notices
this and marks the station as asleep
* when the station is marked asleep, the microcode
refuses to transmit to the station and rejects all
frames queued to it with the failure status code
TX_STATUS_FAIL_DEST_PS (a previous patch handled
this correctly)
* when we need to send frames to the station _although_
it is asleep, we need to tell the ucode how many,
and this is asynchronous with sending so we cannot
just send the frames, we need to wait for all other
frames to be flushed, and then update the counter
before sending out the poll response frames. This
is handled partially in the driver and partially in
mac80211.
In order to do all this correctly, we need to
* keep track of how many frames are pending for each
associated client station (avoid doing it for other
stations to avoid the atomic ops)
* tell mac80211 that we driver-block the PS status
while there are still frames pending on the queues,
and once they are all rejected (due to the dest sta
being in PS) unblock mac80211

We know that the routines in this trace, iwlcore_eeprom_acquire_semaphore
and iwlcore_eeprom_verify_signature, only access CSR registers and thus do
not need the device to be awake if it is EEPROM. But for OTP it is required
for the device to be awake to read these registers. Ensure device is awake
before accessing these registers.

With multi queue devices, its possible that several cpus call
macvlan RX routines simultaneously for the same macvlan device.
We update RX stats counter without any locking, so we can
get slightly wrong counters.
One possible fix is to use percpu counters, to get precise
accounting and also get guarantee of no cache line ping pongs
between cpus.
Note: this adds 16 bytes (32 bytes on 64bit arches) of percpu
data per macvlan device.

znet was including "wireless/i82593.h" (which is a bit wierd), and I
missed that when I relocated i82593.h to drivers/staging/wavelan. Since
I don't have ISA turned-on in my normal .config, I didn't see the build
failures -- mea culpa!

We need to look for the 'shared-pins' property to get
this right.

This patch removes config dependency on x86 to build vmxnet3 driver. Thus
the driver can be built on big endian architectures now. Although vmxnet3
is not supported on VMs other than x86 architecture, all this code goes in
to ensure correctness. If the code is not dependent on x86, it should not
assume little endian architecture in any of its operations.

This fixes the following warning:
WARNING: drivers/net/phy/built-in.o(.devexit.text+0x70): Section mismatch in reference from the function .mdio_gpio_bus_destroy() to the function .devinit.text:.mdio_gpio_bus_deinit()
The function __devexit .mdio_gpio_bus_destroy() references
a function __devinit .mdio_gpio_bus_deinit().
This is often seen when error handling in the exit function
uses functionality in the init path.
The fix is often to remove the __devinit annotation of
.mdio_gpio_bus_deinit() so it may be used outside an init section.

1. This patch is based on the kernel of 2.6.32-rc7
2. In this patch, we enlarge the out buffer size to optimize the
upload speed for the ppp connection. Then it can support the upload of
HSUPA data cards.
