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.

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.

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.

This patch fixes an old problem, which - under certain
circumstances - could cause the device to become
unresponsive.
most of p54pci's rx-ring management is implemented in just
two distinct standalone functions. p54p_check_rx_ring takes
care of processing incoming data, while p54p_refill_rx_ring
tries to replenish all depleted communication buffers.
This has always worked fine on my fast machine, but
now I know there is a hidden race...
The most likely candidate here is ring_control->device_idx.
Quintin Pitts had already analyzed the culprit and posted
a patch back in Oct 2009. But sadly, no one's picked up on this.

We used to free all the Tx queues memory when interface is brought
down and reallocate them again in interface up. This requires
order-4 allocation for txq->cmd[]. In situations like s2ram, this
usually leads to allocation failure in the memory subsystem. The
patch fixed this problem by allocating the Tx queues memory only at
the first time. Later iwl_down/iwl_up only initialize but don't
free and reallocate them. The memory is freed at the device removal
time. BTW, we have already done this for the Rx queue.

The last_phy_res[100] variable is used in an odd
way. The first byte of it is used as a flag, and
the rest as the data. Thus, the array need only
be 61 bytes, since it is just the flag and a
struct iwl_rx_phy_res (which is 60 bytes).
Clean this up by splitting the variable into two:
last_phy_res and last_phy_res_valid, using correct
types for both (struct and bool). While doing all
this also move the variables to the _agn part of

Default WEP keys and regular keys are not allocated
from the same space in the firmware, so we shouldn't
use the same bits to indicate in use.
For default WEP keys, however, mac80211 won't allow
using the same key index twice, so the check is not
necessary at all -- add/remove are perfectly nested
due to those checks.
Other keys are allocated in the device in a global

for that we need to keep the allocation bitmap; but

The current algorithm will sometimes "detect" that
more chains are enabled than are really present in
the device because, for unknown reasons, the ucode
sends up all-zeroes signal values.
The simplest way of solving this is to restrict the
active chains mask to the chains we know are really
present on the device.
This fixes a bug with some devices where, since sometimes
more chains are enabled than really present, the system would hang.

This is an Adaptive Noise Imunity (ANI) implementation for ath5k. I have looked
at both ath9k and HAL sources (they are nearly the same), and even though i
have implemented some things differently, the basic algorithm is practically
the same, for now. I hope that this can serve as a clean start to improve the
algorithm later.
This also adds a possibility to manually control ANI settings, right now only
thru a debugfs file:
* set lowest sensitivity (=highest noise immunity):
echo sens-low > /sys/kernel/debug/ath5k/phy0/ani
* set highest sensitivity (=lowest noise immunity):
echo sens-high > /sys/kernel/debug/ath5k/phy0/ani
* automatically control immunity (default):
echo ani-on > /sys/kernel/debug/ath5k/phy0/ani
* to see the parameters in use and watch them change:
cat /sys/kernel/debug/ath5k/phy0/ani
Manually setting sensitivity will turn the automatic control off. You can also
control each of the five immunity parameters (noise immunity, spur immunity,
firstep, ofdm weak signal detection, cck weak signal detection) manually thru
the debugfs file.
This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band.

ah->mask_reg was used to hold different data throughout the driver.
ath9k_hw_init_interrupt_masks() used it to save the value written to
AR_IMR. ath9k_hw_set_interrupts() used it to hold the interrupt mask as
defined in enum ath9k_int. Those masks differ in many bits.
Use ah->imask instead of ah->mask_reg in ath9k_hw_set_interrupts() and
ath9k_hw_updatetxtriglevel(). That's what the code was meant to do.
ah->imask is initialized in ath9k_start(), so we don't need to

Previously in interrupt handling tasklet, iwlwifi driver only clear/ack
those interrupts that are enabled by the driver through inta_mask.
If the hardware generates unattended interrupts, driver will not ack them,
defeating the interrupt coalescing feature. This results in high number
of interrupts per second and high CPU utilization.
This patch addresses this issue by acking those unattended interrupts
in the tasklet. Local test showed an order of magnitude improvement
in terms of the number of interrupts without sacrificing networking
throughput. This is a workaround for hardware issue.
