ath9k_hw: restore mac address reading logic

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 should fix reading the MAC address from the EEPROM
on AR9003 hardware.

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

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

wl1251: register platform_device to pass board data

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.

rt2x00: rt2800pci: fix tx path by not accessing the skb after it was DMA mapped

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.

cfg80211: Avoid sending IWEVASSOCREQIE and IWEVASSOCRESPIE events with NULL event body

In a scenario, where a cfg80211 driver (station mode) does not send assoc request
and assoc response IEs in cfg80211_connect_result after a successful association
to an AP, cfg80211 sends IWEVASSOCREQIE and IWEVASSOCRESPIE to the user space
application with NULL data. This can cause an issue at the event recipient.

An example of this is when cfg80211 sends IWEVASSOCREQIE and IWEVASSOCRESPIE
events with NULL event body to wpa_supplicant. The wpa_supplicant overwrites
the assoc request and assoc response IEs for this station with NULL data.
If the association is WPA/WPA2, the wpa_supplicant is not able to generate
EAPOL handshake messages, since the IEs are NULL.

With the patch, req_ie and resp_ie will be NULL by avoiding the
assignment if the driver has not sent the IEs to cfg80211. The event sending
code sends the events only if resp_ie and req_ie are not NULL. This
will ensure that the events are not sent with NULL event body.

ath9k-htc: fix lockdep warning and kernel warning after unplugging ar9271 usb device

This patch fixes two warnings below after unplugging ar9271 usb device:
-one is a kernel warning[1]
-another is a lockdep warning[2]

The root reason is that __skb_queue_purge can't be executed in hardirq
context, so the patch forks ath9k_skb_queue_purge(ath9k version of _skb_queue_purge),
which frees skb with dev_kfree_skb_any which can be run in hardirq
context safely, then prevent the lockdep warning and kernel warning after
unplugging ar9271 usb device.

ath9k-htc:respect usb buffer cacheline alignment in reg out path

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).

ath5k: treat RXORN as non-fatal

We get RXORN interrupts when all receive buffers are full. This is not
necessarily a fatal situation. It can also happen when the bus is busy or the
CPU is not fast enough to process all frames.

Older chipsets apparently need a reset to come out of this situration, but on
newer chips we can treat RXORN like RX, as going thru a full reset does more
harm than good, there.

The exact chip revisions which need a reset are unknown - this guess
AR5K_SREV_AR5212 ("venice") is copied from the HAL.

Inspired by openwrt 413-rxorn.patch:
"treat rxorn like rx, reset after rxorn seems to do more harm than good"

ath5k: Use high bitrates for ACK/CTS

There was a confusion in the usage of the bits AR5K_STA_ID1_ACKCTS_6MB and
AR5K_STA_ID1_BASE_RATE_11B. If they are set (1), we will get lower bitrates for
ACK and CTS. Therefore ath5k_hw_set_ack_bitrate_high(ah, false) actually
resulted in high bitrates, which i think is what we want anyways. Cleared the
confusion and added some documentation.
