ed9d01026f cfg80211: Use consistent BSS matching between scan and sme
cfg80211 scan code adds separate BSS entries if the same BSS shows up
on multiple channels. However, sme implementation does not use the
frequency when fetching the BSS entry. Fix this by adding channel
information to cfg80211_roamed() and include it in cfg80211_get_bss()
calls.

Please note that drivers using cfg80211_roamed() need to be modified to
fully implement this fix. This commit includes only minimal changes to
avoid compilation issues; it maintains the old (broken) behavior for
most drivers. ath6kl was the only one that I could test, so I updated
it to provide the operating frequency in the roamed event.

504d4721ee MIPS: Lantiq: Add ethernet driver
This patch adds the driver for the ETOP Packet Processing Engine (PPE32)
found inside the XWAY family of Lantiq MIPS SoCs. This driver makes 100MBit
ethernet work. Support for all 8 dma channels, gbit and the embedded switch
found on the ar9/vr9 still needs to be implemented.

b1608d69cb drivercore: revert addition of of_match to struct device
Commit b826291c, "drivercore/dt: add a match table pointer to struct
device" added an of_match pointer to struct device to cache the
of_match_table entry discovered at driver match time.  This was unsafe
because matching is not an atomic operation with probing a driver.  If
two or more drivers are attempted to be matched to a driver at the
same time, then the cached matching entry pointer could get
overwritten.

This patch reverts the of_match cache pointer and reworks all users to
call of_match_device() directly instead.

e4abce8538 sfc: Use netif_device_{detach,attach}() around reset and self-test
We need to keep the TX queues stopped throughout a reset, without
triggering the TX watchdog and regardless of the link state.  The
proper way to do this is to use netif_device_{detach,attach}() just as
we do around suspend/resume, rather than the current bodge of faking
link-down.

Since we also need to do this during an offline self-test and we
perform a reset during that, add these function calls outside of
efx_reset_down() and efx_reset_up().

ebde6f8acb vmxnet3: Fix inconsistent LRO state after initialization
During initialization of vmxnet3, the state of LRO
gets out of sync with netdev->features.

This leads to very poor TCP performance in a IP forwarding
setup and is hitting many VMware users.

Simplified call sequence:
1. vmxnet3_declare_features() initializes "adapter->lro" to true.

2. The kernel automatically disables LRO if IP forwarding is enabled,
so vmxnet3_set_flags() gets called. This also updates netdev->features.

3. Now vmxnet3_setup_driver_shared() is called. "adapter->lro" is still
set to true and LRO gets enabled again, even though
netdev->features shows it's disabled.

Fix it by updating "adapter->lro", too.

The private vmxnet3 adapter flags are scheduled for removal
in net-next, see commit a0d2730c95
"net: vmxnet3: convert to hw_features".

Patch applies to 2.6.37 / 2.6.38 and 2.6.39-rc6.

Commit 747df2258b ('sfc: Always map MCDI
shared memory as uncacheable') introduced a separate mapping for the
MCDI shared memory (MC_TREG_SMEM).  This means we can no longer easily
include it in the register dump.  Since it is not particularly useful
in debugging, substitute a recognisable dummy value.

This patch cleans up two minor issues in ixgbe_down.  Specifically it
addresses the fact that the VFs should not be pinged until after interrupts
are disabled otherwise they might still get a response.  It also drops the

4ce7cc2b09 iwlagn: support multiple TBs per command
The current "huge" command handling is a bit
confusing, and very limited since only one
command may be huge at a time. Additionally,
we often copy data around quite pointlessly
since we could instead map the existing scan
buffer for example and use it directly.

This patch makes that possible. The first
change is that multiple buffers may be given
to each command (this change was prepared
earlier so callsites don't need to change).
Each of those can be mapped attached to a TB
in the TFD, and the command header can use a
TB (the first one) in the TFD as well.

Doing this allows getting rid of huge commands
in favour of mapping existing buffers. The
beacon transmission is also optimised to not
copy the SKB at all but use multiple TBs.

747df2258b sfc: Always map MCDI shared memory as uncacheable
We enabled write-combining for memory-mapped registers in commit
65f0b417de, but inhibited it for the
MCDI shared memory where this is not supported.  However,
write-combining mappings also allow read-reordering, which may also
be a problem.

I found that when an SFC9000-family controller is connected to an
Intel 3000 chipset, and write-combining is enabled, the controller
stops responding to PCIe read requests during driver initialisation
while the driver is polling for completion of an MCDI command.  This
results in an NMI and system hang.  Adding read memory barriers
between all reads to the shared memory area appears to reduce but not
eliminate the probability of this.

We have not yet established whether this is a bug in our BIU or in the
PCIe bridge.  For now, work around by mapping the shared memory area
separately.

Start/stop TX queue is controlled by TX queue "used" counter.
It is incremented while WRBs are posted to TX queue and
decremented when TX completions are received. This counter was
getting decremented before HW is informed about processing of TX
completions. As used counter is decremented, transmit function
posts new WRBs and creates completion queue full scenario in HW.

fc7707a469 rtlwifi: rtl8192se: Remove need to disable ASPM
When this driver was initially submitted, the system would crash unless
ASPM was disabled. This problem has been fixed.

This patch also adds a printk that outputs the name of the firmware
file that is used.

c84aa5af99 rtlwifi: Move 2 large arrays off stack
In driver rtlwifi, efuse_read() places two relatively large arrays on the
stack - a 1D u8 array of size 128, and a 2D array of u16 with 128 * 4 elements.
With driver rtl8192de, the sizes will be 256 and 256 * 4 respectively. As that
will make the 2D array be 2048 bytes, I have changed the code to use kmalloc to
allocate the space.

054ec92494 iwlagn: fix iwl_is_any_associated
The function iwl_is_any_associated() was intended
to check both contexts, but due to an oversight
it only checks the BSS context. This leads to a
problem with scanning since the passive dwell
time isn't restricted appropriately and a scan
that includes passive channels will never finish
if only the PAN context is associated since the
default dwell time of 120ms won't fit into the
normal 100 TU DTIM interval.

Fix the function by using for_each_context() and
also reorganise the other functions a bit to take
advantage of each other making the code easier to
read.
