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
Chipsets since revision AR5213A (0x59) have hardware counters for PHY errors
which we can read directly from the registers. Older hardware has to use the RX
descriptor status to get a count of PHY errors. This will be used in several
places in the ANI implementation, so a flag is useful.

Update PHY error codes from the HAL, and keep them in statistics for debugging
via the 'frameerrors' file. This will also be used by ANI.

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).

Initialize noise floor variable with a default of -95. This was used
uninitialized in the signal strength (RSSI -> dBm) conversion until the first
noise floor calibration was completed.

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 :)

It's not a phy related funtion; It has more to do with the interrupt handler
and tasklet scheduling, so it belongs to base.c.

Optimize ath5k_hw_calibration_poll() since it is called on every singe
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
Remove static variable ath5k_calinterval which was used as a constant. Use a
#define instead. Also we don't need ah_cal_intval.

This is ANI for ath5k. I have looked ath both the HAL and ath9k sources, while
implementing this, so the basic algorithm is the same. A notable difference is
that i do everything in a tasklet, while ath9k and HAL do larger parts in the
interrupt handler. Also i have only one routine for raising imm

Bob,
a recent wireless-testing kernel with both of your patches from Kernel Bug
#14342 run for two days now without the failed reset error message.
However, different from my previous tries I did not include Bruno's ANI
patch, so the success might be either because of your patchset or the
omission
