Jussi Kivilinna 7f29a3baa8 asix: fix setting mac address for AX88772
Setting new MAC address only worked when device was set to promiscuous mode.
Fix MAC address by writing new address to device using undocumented command
AX_CMD_READ_NODE_ID+1. Patch is tested with AX88772 device.

Reinette Chatre 1382c71c76 Revert "iwlwifi: Send broadcast probe request only when asked to"
This reverts commit 21b2d8bd2f.

As explained by Johannes:
When we
build a probe request frame in the buffer with the SSID, we could
arrive over the limit of 200 bytes. When we build it in the buffer
without the SSID (wildcard) we don't arrive over 200 bytes, but the
ucode still allows direct probe in addition because it has an internal
buffer that is larger when it inserts the SSID...

Reinette Chatre 1d79e53c56 iwl3945: fix memory corruption
Recent patch "iwlwifi: move 3945 clip groups to 3945 data" exposed a memory
corruption problem. When initializing the clip groups the code was
mistakenly using the iwlagn rate count, not the 3945 rate count. This
resulted in more memory being written than was allocated.

"iwlwifi: move 3945 clip groups to 3945 data" moved the location where the
clip groups are stored and the impact is now severe in that the number of
configured TX queues is modified. Previously the
"temperature" field was overwritten, which did not seem to affect the
operation.

Fix this one instance where wrong rate count was used. I also noticed one
more location where the iwlagn rate count was used to index an iwl3945
array, fix this. I also modified one location that modified the iwlagn rate
count to obtain the iwl3945 rate count ... just use the iwl3945 rate count
directly.

This fixes http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2165 and

Emese Revfy 52cf25d0ab Driver core: Constify struct sysfs_ops in struct kobj_type
Constify struct sysfs_ops.

This is part of the ops structure constification
effort started by Arjan van de Ven et al.

Benefits of this constification:

 * prevents modification of data that is shared
   (referenced) by many other structure instances
   at runtime

 * detects/prevents accidental (but not intentional)
   modification attempts on archs that enforce
   read-only kernel data at runtime

 * potentially better optimized code as the compiler
   can assume that the const data cannot be changed

 * the compiler/linker move const data into .rodata
   and therefore exclude them from false sharing

of cleanups, by sharing low level IO code without requiring
an own function for every piece of data.

Also drivers can extend the attributes with own data fields
and use that in the low level function.

This makes the class attributes the same as sysdev_class attributes
and plain attributes.

This will allow further cleanups in drivers.

Anton Vorontsov 0eddba525c gianfar: Fix TX ring processing on SMP machines
Starting with commit a3bc1f11e9 ("gianfar: Revive SKB
recycling") gianfar driver sooner or later stops transmitting any
packets on SMP machines.

start_xmit() prepares new skb for transmitting, generally it does
three things:

1. sets up all BDs (marks them ready to send), except the first one.
2. stores skb into tx_queue->tx_skbuff so that clean_tx_ring()
   would cleanup it later.
3. sets up the first BD, i.e. marks it ready.

Here is what clean_tx_ring() does:

1. reads skbs from tx_queue->tx_skbuff
2. checks if the *last* BD is ready. If it's still ready [to send]
   then it it isn't transmitted, so clean_tx_ring() returns.
   Otherwise it actually cleanups BDs. All is OK.

Now, if there is just one BD, code flow:

- start_xmit(): stores skb into tx_skbuff. Note that the first BD
  (which is also the last one) isn't marked as ready, yet.
- clean_tx_ring(): sees that skb is not null, *and* its lstatus
  says that it is NOT ready (like if BD was sent), so it cleans
  it up (bad!)
- start_xmit(): marks BD as ready [to send], but it's too late.

We can fix this simply by reordering lstatus/tx_skbuff writes.

Sujith 4fa0043731 mac80211: Fix HT rate control configuration
Handling HT configuration changes involved setting the channel

notification to the driver.

This behavior changed after the off-channel changes. Now, the channel
is not updated with the new HT params in enable_ht() - instead, it
is now done when the scan work terminates. This results in the driver
depending on stale information, defaulting to non-HT mode always.

Fix this by passing the new channel type to the driver.

Johannes Berg b08dfd0435 iwlwifi: load firmware asynchronously before mac80211 registration
At the wireless summit in Portland we discussed a way of
loading firmware asynchronously from ->probe() before
registration to mac80211, in order to register with the
wireless subsystems with complete information in cases
where firmware is required to know parameters.

This is not yet the case in iwlwifi, but for some new
features we're working on it will be the case since
those will only be supported by new firmware images.

Hence, to start with, convert iwlwifi to load firmware
asynchronously from probe, unbinding the device when
firmware loading fails, and only registering with the
wireless subsystems after firmware has been loaded
successfully.

Future patches will hook into this to register the
new firmware capabilities, depending on the firmware
API version.

Compiling rt2800pci with CONFIG_RT2800PCI_SOC fails with "... rt2880pci.c:
error: incompatible type for argument 2 of 'rt2x00soc_probe'".

Fix this by using &rt2800pci_ops instead of rt2800pci_ops.

Ming Lei a9f042cbe5 ath9k: fix lockdep warning when unloading module
Since txq->axq_lock may be hold in softirq context, it must be
acquired with spin_lock_bh() instead of spin_lock() if softieq is
enabled.

The patch fixes the lockdep warning below when unloading ath9k modules.

Sathya Perla f31e50a802 be2net: fix tx completion polling
In tx/mcc polling, napi_complete() is being incorrectly called
before reaping tx completions. This can cause tx compl processing
to be scheduled on another cpu concurrently which can result in a panic.
This if fixed by calling napi complete() after tx/mcc compl processing
but before re-enabling interrupts (via a cq notify).

Vladislav Zolotarov c16cc0b464 bnx2x: Tx barriers and locks
[Resending with the proper subject. Sorry for the mess. ]

This patch is based on the RFC of Stanislaw Gruszka.

More specifically it fixes two possible races:
- One, described by Stanislaw, may lead to permanent disabling of the Tx
queue.
This is fixed by adding the smp_wmb() to propagate the BD consumer
change towards the memory.
- Second may lead to bnx2x_start_xmit() returning NETDEV_TX_BUSY.
This is fixed by taking a tx_lock() before rechecking the number of
available Tx BDs.

thanks,
vlad

Manuel Lauss 9bdcf336d0 MIPS: Alchemy: devboard register abstraction
All Alchemy development boards have external CPLDs with a few registers
in them.  They all share an identical register layout with only a few
minor differences (except the PB1000) in bit functions and base
addresses.

This patch
- adds a primitive facility to initialize and use these external
  registers,
- replaces all occurrences of bcsr->xxx accesses with calls to the new
  functions (the pb1200 cascade irq handling code is special).
- collects BCSR register information scattered throughout the board
  headers in a central place.

Move TC_PRIO_CONTROL check and queue remapping into

netif_stop_subqueue().  Even if this is resolved and the
correct queue is stopped it can result in a queue being
blocked by TC_PRIO_CONTROL frames uneccesarily.  Moving
this into the select_queue routine maintains alignment
between tx_rings and qdisc queues.

Patrick McHardy 3729d50212 rtnetlink: support specifying device flags on device creation
commit e8469ed959c373c2ff9e6f488aa5a14971aebe1f
Author: Patrick McHardy <kaber@trash.net>
Date:   Tue Feb 23 20:41:30 2010 +0100

Support specifying the initial device flags when creating a device though
rtnl_link. Devices allocated by rtnl_create_link() are marked as INITIALIZING
in order to surpress netlink registration notifications. To complete setup,
rtnl_configure_link() must be called, which performs the device flag changes
and invokes the deferred notifiers if everything went well.

Two examples:

# add macvlan to eth0
#
$ ip link add link eth0 up allmulticast on type macvlan

Linus Torvalds 9e3bd91908 b43: fall back gracefully to PIO mode after fatal DMA errors
This makes the b43 driver just automatically fall back to PIO mode when
DMA doesn't work.

The driver already told the user to do it, so rather than have the user
reload the module with a new flag, just make the driver do it
automatically. We keep the message as an indication that something is
wrong, but now just automatically fall back to the hopefully working PIO
case.

This is causing baseband related issues on AR9160 and AR9130 based

This patch fixes these issues by overriding the initvals, effectively

John Fastabend a922afb64d ixgbe: do not stop tx queues in ixgbe_set_tso
Disabling TSO can cause the dev_watchdog timer to be triggered because
when TSO is disabled netif_tx_stop_all_queues is called.  If the watchdog
timer fires while the queues are stopped and traffic has not recently been
sent on a paticular queue this is falsly identified as a hang and
ndo_tx_timeout() is called.  This is ocossionally seen during testing.

This removes the netif_tx_stop_all_queues() it is not needed.  The scheduler
submits skb's with dev_hard_start_xmit(), this checks if netif_needs_gso and
if so it calls dev_gso_segment.  Disabling TSO will cause dev_hard_start_xmit()
to do the gso processing.   However ixgbe does not use the features flags to
determine if it needs to use tso or not instead it uses skb->gso_size so
ixgbe will process these frames correctly regardless of the netdev features
flag.
