181fb18daa ath9k: Fix a PLL hang issue observed with AR9485.
When this PLL hang issue is seen, both Rx and Tx fail to work.
The sqsum_dvc needs to be below 2000 for a good chip. During
this issue the sqsum_dvc value is beyond 80000 and only a
full reset can solve this problem.

0d95521ea7 ath9k: use split rx buffers to get rid of order-1 skb allocations
With this change, less CPU time is spent trying to look for consecutive
pages for rx skbs. This also reduces the socket memory required for IP/UDP
reassembly.
Only two buffers per frame are supported. Frames spanning more buffers
will be dropped, but the buffer size is enough to handle the required
AMSDU size.

00e0003e09 ath9k_hw: Fix opmode initialization
Commit "ath9k_hw: Relocate Opmode initialization"
moved the opmode initialization before the STA_ID1 register
was programmed with defaults. This changed the original
behaviour because the re-programming code doesn't take into
account the existing value in the register. Both ath9k and ath9k_htc
were not affected by this change because the opmode is
re-initialized after every reset, when RX is started.

Revert to the original behavior, except keep it outside the
REGWRITE block. This would help remove extraneous opmode calls
in the driver core.

45cbad6a12 cfg80211: Allow non-zero indexes for device specific pair-wise ciphers
Some vendor specific cipher suites require non-zero key indexes for pairwise
keys, but as of currently, the cfg80211 does not allow it.

As validating they cipher parameters for vendor specific cipher suites is the

non-zero pairwise key indexes for vendor specific ciphers.

0e4722524d ath5k: use tracing for packet tx/rx dump
This adds a few tracepoints to ath5k driver transmit and
receive callbacks in order to record packet traffic.
We record the entire packet in the trace buffer so that
the data can be extracted with trace-cmd and external
plugins.

Compared to the previous debugging calls, this approach
removes an out-of-line function call from the tx and rx
paths in the compiled-in-but-disabled case, while
improving the ability to process the logged data.

A new option, CONFIG_ATH5K_TRACER, is added so that one
may disable the tracepoints completely.

5719efdde1 ath: Add function to check if 4.9GHz channels are allowed
This adds a helper function to ath/regd.c which can be asked if 4.9GHz channels
are allowed for a given regulatory domain code. This keeps the knowledge of
regdomains and defines like MKK9_MKKC in one place. I'm passing the regdomain
code instead of the ath_regulatory structure because this needs to be called
quite early in the driver inititalization where ath_regulatory is not available
yet in ath5k.

I'm using MKK9_MKKC only because this is the regdomain in the 802.11j enabled
sample cards we got from our vendor. I found some hints in HAL code that this
is used by Atheros to indicate 4.9GHz channels support and that there might be
other domain codes as well, but as I don't have any documentation I'm just
putting in what I need right now. It can be extended later.

5bec3e5ade ath9k: fix tx queue index confusion in debugfs code
Various places printing tx queue information used various different ways to
get a tx queue index for printing statistics. Most of these ways were wrong.

ATH_TXQ_AC_* cannot be used as an index for sc->tx.txq, because it is only
used internally for queue assignment.

One place used WME_AC_* as a queue index for sc->debug.stats.txstats, however
this array uses the ath9k_hw queue number as well.

Fix all of this by always using the ath9k_hw queue number as an index, and
always looking it up by going through sc->tx.txq_map.

It does not make much sense to keep the current virtual wiphy implementation
any longer - it adds significant complexity, has very few users and is still
very experimental. At some point in time, it will be replaced by a proper

helps with fixing the remaining driver issues and adding further improvements.

Instead of spreading ath_wake_mac80211_queue() calls over multiple places
in the tx path that process the tx queue for completion, call it only
where the pending frames counter gets decremented, eliminating some
redundant checks.
To prevent queue draining from waking the queues prematurely (e.g. during
a hardware reset), reset the queue stop state when draining all queues,
as the caller in main.c will run ieee80211_wake_queues(hw) anyway.

c7c1806098 ath9k: Fix power save usage count imbalance on deinit
While unloading the driver, the ps_usecount is incremented
before configuring gpio registers in deinit_device.
But it is failed to restore the ps_usecount after that.
The problem is that the chip is forcibly moved to FULL SLEEP
by radio_disable when mac80211 is reporting as idle
though ps_usecount is not zero.

This patch retores ps_usecount properly and ensures that
the chip is always moved to full sleep only if ps usage
count is zero which also helps in debugging deadbeef on
multivif case. And also fixes the following warning.

ath: DMA failed to stop in 10 ms AR_CR=0xdeadbeef AR_DIAG_SW=0xdeadbeef
ath: Could not stop RX, we could be confusing the DMA engine when we
start RX up

ac45c12dfb ath9k_hw: Fix incorrect macversion and macrev checks
There are few places where we are checking for macversion and revsions
before RTC is powered ON. However we are reading the macversion and
revisions only after RTC is powered ON and so both macversion and
revisions are actully zero and this leads to incorrect srev checks

Incorrect srev checks can cause registers to be configured wrongly and can
cause unexpected behavior. Fixing this seems to address the ASPM issue that
we have observed. The laptop becomes very slow and hangs mostly with ASPM L1
enabled without this fix.

fix this by reading the macversion and revisisons even before we start
using them. There is no reason why should we delay reading this info
until RTC is powered on as this is just a register information.

e5e2f24b3e wl12xx: disable auto-arp
The auto-arp feature sometimes has unexpected side effects (e.g. firmware
crashes, no ARP replies, etc.)
disable it until it will be solved.

ea45b2cbf5 wl12xx: Increase scan channel dwell time for passive scans
The passive scan channel dwell time currently used is 30-60TU. A typical
beacon interval for AP's is 100TU. This leads to a ~30% worst-case probability
of finding an AP via passive scanning.

For 5GHz bands for DFS frequencies passive scanning is the only scanning
option. Hence for these, the probability of finding an AP is very low.

To fix this, increase the passive channel scan dwell times (also the early
leave value, as 5GHz channels are still typically very silent.) Use a value
of 100TU, because that covers most typical AP configurations.

Based on testing the probability of finding an AP (100TU beacon interval) on
a single scan round are as follows (based on 100 iterations):

dwell min/max (TU)   | probability
---------------------+------------
30/60                | 35%
60/60                | 56%
80/80                | 77%
100/100              | 100%

Total scan times now and after the change:

Region | Before (s) | After (s)
-------+------------+----------
00     | 0.77       | 1.48
FI     | 0.95       | 2.01
US     | 0.91       | 1.76

8e2de74e78 wl12xx: wrong values are returned in gpio_power_write()
Return values were assigned to incorrect var / weren't assigned.
fix it, and defer mutex_lock after the sanity checks.
