- Modify the the platform macro define like as cpu_is_xxx()
for supporting Mergrez chip.
- Config MIIGSK for FEC IP to enable RMII mode. MX25,MX53,
and MX6Sololite use FEC IP, which need to config the MIIGSK
registers memory map for RMII and MII.
- Correct device id_table entry name for differnt IP.
- Rewrite FEC MAC address by net_device address when reset FEC,
which can avoid invalid MAC address to result in FEC cannot
work.

- Add NAPI methods.
NAPI can improve the performance of high-speed networking,
which can reduce the cpu loading of interrupt generate and

- Enet RX FIFO overruns number has been reduced by NAPI method.

The issue is hard to reproduce in normal envrionment. And
the reproduce rate is about 40% when doing VTE auto test.
while the driver did report being busy when the link is down
or no transmission buffers are available, it did not stop the
queue, causing instant retries. furthermore, transmission being
triggered with link down was caused by unconditional queue
wakes, especially on timeouts.
Now, wake queue only if link is up and transmission buffers
are available, and dont forget to wake queue when link has
been adjusted. next, add stop queue notification upon driver
induced transmission problems, so network stack has a chance
to handle the situation.

Last May we started working on cleaning up ath6kl driver which is
currently in staging. The work has happened in a separate
ath6kl-cleanup tree:
http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary
After over 1100 (!) patches we have now reached a state where I would
like to start discussing about pushing the driver to the wireless
trees and replacing the staging driver.
The driver is now a lot smaller and looks like a proper Linux driver.
The size of the driver (measured with simple wc -l) dropped from 49
kLOC to 18 kLOC and the number of the .c and .h files dropped from 107
to 22. Most importantly the number of subdirectories reduced from 26
to zero :)
There are two remaining checkpatch warnings in the driver which we
decided to omit for now:
drivers/net/wireless/ath/ath6kl/debug.c:31:
WARNING: printk() should include KERN_ facility level
drivers/net/wireless/ath/ath6kl/sdio.c:527:
WARNING: msleep < 20ms can sleep for up to 20ms;
see Documentation/timers/timers-howto.txt
The driver has endian annotations for all the hardware specific
structures and there are no sparse errors. Unfortunately I don't have
any big endian hardware to test that right now.
We have been testing the driver both on x86 and arm platforms. The
code is also compiled with sparc and parisc cross compilers.
Notable missing features compared to the current staging driver are:
o HCI over SDIO support
o nl80211 testmode
o firmware logging
o suspend support
Testmode, firmware logging and suspend support will be added soon. HCI
over SDIO support will be more difficult as the HCI driver needs to
share code with the wifi driver. This is something we need to research
more.
Also I want to point out the changes I did for signed endian support.
As I wasn't able to find any support for signed endian annotations I
decided to follow what NTFS has done and added my own. Grep for sle16
and sle32, especially from wmi.h.
Various people have been working on the cleanup, the hall of
fame based on number of patches is:

This patch change is very trivial and simply just add
cpu_is_mx6dl() or using cpu_is_mx6 to replace cpu_is_mx6q

such as sdhc etc.

Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).
To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.
Hope people are OK with tiny include file.
Note, that mm_types.h is still dragged in, but it is a separate story.

The original FEC_MII_TIMEOUT was set to 1ms, which is too low when
passed to the usecs_to_jiffies macro.
On ARM one jiffy is 10ms, so use msecs_to_jiffies instead and use
a timeout of 30ms, which corresponds to 3 jiffies.
After running 3 hours NFS boots, the MDIO timeout do not occur
anymore.

Using platform ids to handle differences between different SoCs.
The default rx fifo global mask register, newly introduced in mx6q,
is 0xffffffff and the reset value in Message buffers(can be reused as the
memory of rx fifo filter table) is none zero, it will wrongly cause the
can to be unable to recevie packets due to filter.
We need to clear it to make sure to receive all packets.

Integrate atheros driver package from atheros company.
It's mainly for AR6003.
NGR00132491-1 ath6kl upgrade: change Kconfig
This series of patches are for upgrading Atheros AR6003(ath6kl)
in 31 kernel to 35 kernel.
The WLAN_80211 config option has been changed to WLAN in 35 kernel.
ENGR00132491-2 ath6kl upgrade: add missed semaphore.h headfile
ENGR00132491-3 ath6kl upgrade: enable WEXT implicitely
Atheros ath6kl driver is based on WEXT subsystem and therefore
needs to select CONFIG_WIRELESS_EXT for compiling.
However in the latest kernel such as 2.6.35,
this option can no longer be configured using menuconfig.
So we select it when the user selects ath6kl driver to compile.

commit 31c15a2f24ebdab14333d9bf5df49757842ae2ec upstream.
Virtual Machines with emulated e1000 network adapter running on Parallels'
server were seeing kernel panics due to the e1000 driver dereferencing an
unexpected NULL pointer retrieved from buffer_info->skb.
The problem has been addressed for the e1000e driver, but not for the e1000.
Since the two drivers share similar code in the affected area, a port of the
following e1000e driver commit solves the issue for the e1000 driver:
commit 9ed318d546a29d7a591dbe648fd1a2efe3be1180

e1000e: save skb counts in TX to avoid cache misses
In e1000_tx_map, precompute number of segements and bytecounts which
are derived from fields in skb; these are stored in buffer_info. When
cleaning tx in e1000_clean_tx_irq use the values in the associated
buffer_info for statistics counting, this eliminates cache misses
on skb fields.

commit d6ee27eb13beab94056e0de52d81220058ca2297 upstream.
When we remove a key, we put a key index which was supposed
to tell the fw that we are actually removing the key. But
instead the fw took that index as a valid index and messed
up the SRAM of the device.
This memory corruption on the device mangled the data of
the SCD. The impact on the user is that SCD queue 2 got
stuck after having removed keys.
The message is the log that was printed is:
Queue 2 stuck for 10000ms
This doesn't seem to fix the higher queues that get stuck
from time to time.
