When I set up multiple VAPs with ath9k, I encountered an issue that
the traffic may be lost after a while.
The detailed phenomenon is
1. After a while the clients connected to one of these VAPs will get
into a state that no broadcast/multicast packets can be transfered
successfully while the unicast packets can be transfered normally.
2. Minutes latter the unitcast packets transfer will fail as well,
because the ARP entry is expired and it can't be freshed due to the
broadcast trouble.
It's caused by the group key overwritten and someone discussed this
issue in ath9k-devel maillist before, but haven't work out a fix yet.
I referred the method in madwifi, and made a patch for ath9k.
The method is to set the high bit of the sender(AP)'s address, and
associated that mac and the group key. It requires the hardware
supports multicast frame key search. It seems true for AR9160.
Not sure whether it's the correct way to fix this issue. But it seems
to work in my test. The patch is attached, feel free to revise it.

This patch introduces the parity errors handling code for 57710 and 57711 chips.
HW is configured to stop all DMA transactions to the host and sending packets to the network
once parity error is detected, which is meant to prevent silent data corruption.
At the same time HW generates the attention interrupt to every function of the device where parity
has been detected so that driver can start the recovery flow.
The recovery is actually resetting the chip and restarting the driver on all active functions
of the chip where the parity error has been reported.

Even the initial single/dual stream values will be overridden later when
issue link quality command; but still make sense not to use hard-code
value during initialization. Single/Dual stream mask are used to indicate the
best antenna for SISO/MIMO; different NIC has different tx antenna
configuration; so the parameter need to based on the valid tx antenna.
1x2 device: single tx antenna available, only SISO is valid
configuration, but still need to set up MIMO configuration, so set it up
with antenna A & B as default.
2x2 device: two tx antenna available, dual_stream will use both valid
antenna.

choice the second and third antenna for dual_stream.

According to tests, both TSF lower and upper registers kept counting, so
the higher part could have been updated after the lower part has been
read, as shown in the following log where the upper part is read first
and the lower part next.
tsf = {00000003-fffffffd}
tsf = {00000003-00000001}
tsf = {00000004-0000000b}
This patch corrects this by checking that the upper part has not been
changed while the lower part was read. It has been tested in an IBSS
network where artifical IBSS merges have been done in order to trigger
hundreds of rollover for the TSF lower part.
It follows the logic mentionned by Derek, with only 2 register reads
needed at each additional steps instead of 3 (the minimum number of
register reads is still 3).

Once upon a time the AR_EEPROM_MAC macro was added to let us
add a random attribute to the three 4-bytes of MAC addresses
entries we read from the EEPROM. This was good while a random
high-enough value was used which did not conflict with any
of the already existing enum eeprom_param values. With AR9003
support the enums overlap and it means we either increment
the random offset or just restore the reading logic to match
what the HAL has. I choose to do the later to synchronize
the logic on both code bases.

This is used only once by ath9k_hw_process_ini() to
write an array of phy registers through REG_WRITE_ARRAY(),
but we already call REG_WRITE_ARRAY() multiple times
on the same caller so just remove this pointless wrapper.
We'll eventually just move the ath9k_hw_process_ini()
caller as an callback to abstract away between different
hardware families.
Although this change is subtle I should note that this
does change the delay pattern on writing the next series
of registers. REG_WRITE_ARRAY() uses a counter for each
register write and does a udelay(1) every 64 writes. By
removing this call it means that the counter is processed
for all the iniBB_RfGain registers and is incremented
on ath9k_hw_process_ini(), before this the after the call
ath9k_hw_write_regs() was made the register counter was
kept at the same index number prior to the call.

wl1251 is embedded chip that can be connected using SDIO bus, and is not
an actual SDIO card. For this reason there is a need to pass some board
specific data, like 'EEPROM is attached' flag or power control callback.
However currently there is no way to pass this data through SDIO subsystem,
so this patch registers dummy platform_device to allow that, until we
have a better solution to this.

rt2800pci used the callback write_tx_desc to write the tx descriptor but
also to update the txwi which is part of the dma mapped skb. Since the
memory was already DMA mapped _before_ the call to write_tx_desc the
device didn't get the txwi data at all or only sporadically.
The call order is basically as follows (from rt2x00queue.c):
1) write_tx_data
2) rt2x00queue_map_txskb
3) write_tx_desc
Hence, we shouldn't touch the skb in write_tx_desc anymore.
To fix this issue create a new rt2800pci_write_tx_data callback and use it
for updating the txwi _before_ the memory gets DMA mapped.
The tx descriptor is still written (as before) in write_tx_desc.
This patch allows basic TX on an rt305x soc device but I'm pretty sure
that it will fix pci based cards as well. I can associate just fine with
an AP now but I wasn't able to get a wpa secured connection working yet.

Some wl1251 hardware configurations (like in WG7210 module) have
EEPROM attached where NVS data is kept, which includes MAC address.
In such configurations, let's read default MAC address from EEPROM,
instead of using random one.

Correct fix for the "ioremap() causes build failure on S390" should have been
a dependancy on HAS_IOMEM. So we add this dependancy also (and leave the driver
in the ARM section for now).

When shutting down the watchdog timer, special care must be taken
not to overwrite other bits in the register, as it may be shared
with other peripherals.
For example, on the Arcom Vulcan, the register is shared between
the watchdog and the PCI reset line...

A previous fix changed the WDTP function to use the period directly,
rather than subtracting from 63. However the mask generation was
not changed, so the mask was coming out as 0. This patch fixes it.

When Wacom devices wake up from a sleep, the switch mode command
(wacom_query_tablet_data) is needed before wacom_open is called.
wacom_query_tablet_data should not be executed inside wacom_open
since wacom_open is called more than once during probe.
wacom_retrieve_hid_descriptor is removed from wacom_resume due
to the fact that the required descriptors are stored properly
upon system resume.

The ixgbe driver was setting up 82598 hardware correctly, so that
when promiscuous mode was enabled hardware stripping was turned
off. But on 82599 the logic to disable/enable hardware stripping
is different, and the code was not updated correctly when the
hardware vlan stripping was enabled as default.
This change comprises the creation of two new helper functions
and calling them from the right locations to disable and enable
hardware stripping of vlan tags at appropriate times.

In ath9k-htc register out path, ath9k-htc will pass skb->data into
usb hcd and usb hcd will do dma mapping and unmapping to the buffer
pointed by skb->data, so we should pass a cache-line aligned address.
This patch replace __dev_alloc_skb with alloc_skb to make skb->data
pointed to a cacheline aligned address simply since ath9k-htc does not
skb_push on the skb and pass it to mac80211, also use kfree_skb to free
the skb allocated by alloc_skb(we can use kfree_skb safely in hardirq
context since skb->destructor is NULL always in the path).
