Subject: ath5k: remove stale function declarations, make some functions static

Remove all unnecessary function declarations from ath5k.h.  Comment out
unused functions.  Remove ath5k_hw_get_tsf32(), which is too trivial to
be commented out.  Make functions static if suggested by sparse.  Make
ath5k_pm_ops static.

Subject: ath5k: Fix TX/RX padding for all frames

Currently, the padding position is based on
ieee80211_get_hdrlen_from_skb(). This is not correct since the HW does
padding on RX (and expect the same padding to be present on TX) at the
following position :

- management : 24 + 6 if 4-addr format
- control    : 24 + 6 if 4-addr format
- data       : 24 + 6 if 4-addr format + 2 if QoS
- invalid    : 24 + 6 if 4-addr format

whereas ieee80211_get_hdrlen_from_skb() is :

- management : 24
- control    : 16 except for ACK/CTS where it is 10
- data       : 24 + 6 if 4-addr format + 2 if QoS + 2 if QoS & order
- invalid    : 24

So, correct frames are not affected : management frames do not use
4-addr format, control frames have no body and invalid frames are ...
not valid by definition. However, in order to use monitor interface for
debugging purpose, one must be able to send/receive any frames, be it
correct or not. Such frames are affected by incorrect padding.

Moreover, since padding is added on TX, we need to remove it before
calling ieee80211_tx_status. This affect TX packets received by monitor
interfaces.

It has been tested between an ath5k based card (AR5212) and an ar9170usb
based card (netgear WNDA3100) using a frame generator and a monitor
interface for each card.

v2: Added ath5k_add_padding / ath5k_remove_padding

Subject: ath5k: add antenna statistics and debugfs file for antenna settings

keep statistics about which antenna was used for TX and RX. this is used only
for debugging right now, but might have other applications later.

add a new file 'antenna' in debugfs (/sys/kernel/debug/ath5k/phy0/antenna) to show
antenna use statistics and antenna diversity related register values. it can
also be used to set the antenna mode until we have proper support for that in
iw:
  - echo diversity > antenna: use default antenna mode (RX and TX diversity)
  - echo fixed-a > antenna: use fixed antenna A for RX and TX
  - echo fixed-b > antenna: use fixed antenna B for RX and TX
  - echo clear > antenna: reset antenna statistics

Subject: ath5k: remove double opmode definition

opmode (operating mode) was defined in struct ath5k_hw and struct ath5k_softc.
remove it from ath5k_hw and use only from ath5k_softc (sc->opmode).

(btw: what's the meaning of opmode when we have multiple interfaces?)

Subject: ath5k: add debugfs file frameerrors

add a debugfs file to see different RX and TX errors as reported in our status
descriptors. this can help to diagnose driver problems.

statistics can be cleared by writing 'clear' into the frameerrors file.

example:

# cat /sys/kernel/debug/ath5k/phy0/frameerrors
RX
---------------------
CRC     27      (11%)
PHY     3       (1%)
FIFO    0       (0%)
decrypt 0       (0%)
MIC     0       (0%)
process 0       (0%)
jumbo   0       (0%)
[RX all 245]

TX
---------------------
retry   2       (9%)
FIFO    0       (0%)
filter  0       (0%)
[TX all 21]

Subject: ath5k: remove static calibration interval variable

Remove static variable ath5k_calinterval which was used as a constant. Use a
#define instead. Also we don't need ah_cal_intval.

Subject: ath5k: remove the use of SWI interrupt

We don't need to generate a software interrupt (SWI) just to schedule a tasklet
- we can just schedule the tasklet directly.

Rename constants, names, etc to reflect the fact that we don't use SWI any more.

Also move the flag handling into the tasklet and prepare it to behave correctly
when there are multiple flags present.

Keep an exponentially weighted moving average of the beacon RSSI in our BSS.
It will be used by the ANI implementation.

The averaging algorithm is copied from rt2x00, Thanks :)

Subject: ath5k: simplify MIB counters

Let's keep MIB counter statistics in our own statistics structure and only
convert it to ieee80211_low_level_stats when needed by mac80211. Also we don't
need to read profile count registers in the MIB interrupt (they don't trigger
MIB interrupts).

Subject: net: convert multicast list to list_head

Converts the list and the core manipulating with it to be the same as uc_list.

+uses two functions for adding/removing mc address (normal and "global"
 variant) instead of a function parameter.
+removes dev_mcast.c completely.
+exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for
 manipulation with lists on a sandbox (used in bonding and 80211 drivers)

From 2111ac0d888767999c7dd6d1309dcc1fb8012022 Mon Sep 17 00:00:00 2001

Subject: ath5k: Adaptive Noise Immunity (ANI) Implementation

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.

+ * DOC: Basic ANI Operation
+ *
+ * Adaptive Noise Immunity (ANI) controls five noise immunity parameters
+ * depending on the amount of interference in the environment, increasing
+ * or reducing sensitivity as necessary.
+ *
+ * The parameters are:
+ *   - "noise immunity"
+ *   - "spur immunity"
+ *   - "firstep level"
+ *   - "OFDM weak signal detection"
+ *   - "CCK weak signal detection"
+ *
+ * Basically we look at the amount of ODFM and CCK timing errors we get and then
+ * raise or lower immunity accordingly by setting one or more of these
+ * parameters.
+ * Newer chipsets have PHY error counters in hardware which will generate a MIB
+ * interrupt when they overflow. Older hardware has too enable PHY error frames
+ * by setting a RX flag and then count every single PHY error. When a specified
+ * threshold of errors has been reached we will raise immunity.
+ * Also we regularly check the amount of errors and lower or raise immunity as
+ * necessary.

Subject: ath5k: clean up queue manipulation

Review spotted a couple of strange invocations to
ieee80211_wake_queues that could potentially cause problems:

 - queues are awakened in the calibration tasklet before
   phy calibration, and then again after calibration

 - queues are awakened inside reset when we're trying to
   drain the ath5k transmit queues, and again after
   reset is completed (in callers to ath5k_reset_wake).

In both cases the first wake is unnecessary, so remove it.

Subject: ath5k: fix race condition in tx desc processing

As pointed out by Benoit Papillault, there is a potential
race condition between the host and the hardware in reading
the next link in the transmit descriptor list:

cpu0              hw
                  tx for buf completed
                  raise tx_ok interrupt
process buf
buf->ds_link = 0
                  read buf->ds_link

This change checks txdp before processing a descriptor
(if there are any subsequent descriptors) to see if
hardware moved on.  We'll then process this descriptor on
the next tasklet.

Subject: 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.

Subject: 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"

Subject: ath5k: drop warning on jumbo frames

Jumbo frames are not supported, and if they are seen it is likely
a bogus frame so just silently discard them instead of warning on
them all time. Also, instead of dropping them immediately though
move the check *after* we check for all sort of frame errors. This
should enable us to discard these frames if the hardware picks
other bogus items first. Lets see if we still get those jumbo
counters increasing still with this.

Jumbo frames would happen if we tell hardware we can support
a small 802.11 chunks of DMA'd frame, hardware would split RX'd
frames into parts and we'd have to reconstruct them in software.
This is done with USB due to the bulk size but with ath5k we
already provide a good limit to hardware and this should not be
happening.

This is reported quite often and if it fills the logs then this
needs to be addressed and to avoid spurious reports.
