2009-02-13ath5k: Don't call reset on config_interfaceNick Kossifidis
* We call reset too often and this can result various PHY problems. On config_interface we don't need to reset the whole device. TODO: Create a function hw_fast_reset that only resets the PCU (tx/rx stuff) and not the whole device so that we can use this for stuck beacons etc. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

2009-02-13ath5k: Update RF Buffer handlingNick Kossifidis
* Use the new way to modify rf buffer and put some rf buffer documentation on rfbufer.h * Merge all rf regs functions to one * Sync with legacy HAL and Sam's HAL * Set gain_F settings so that gain_F optimization engine works on RF5111/RF5112 (note that both HALs only use step 0 for RF5111 and they don't use gain_F optimization for this chip, code is there but is never used) Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

2009-02-13ath5k: Update gain_F calibration code and add documentationNick Kossifidis
* Update and cleanup rf gain optimization code * Add comments and refferences to docs and use sane function names * Use only step index on ath5k_gain, no need to have a pointer to the current step since we can determine te step from it's index, this also allows us to put all other structs on rfgain.h and cleanup ath5k.h a little * No need for ah_rfgain variable, we use ah_gain.g_state for everything * Tested on RF2112B chip but gain_F calibration is not yet done (we will finish this on the next patch where we'll rewrite rf-buffer handling) * Use initial rf gain settings for 2316 and 2317 SoCs introduced on a previous patch It seems big but it's mostly cleanup, very few functional changes have been made on phy.c Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

2009-02-13ath5k: PHY code cleanupNick Kossifidis
* Clean up initial rf buffer settings (new file rfbufer.h) and introduce a new way to access specific rf registers (will use it later) * Clean up initial rf gain settings by moving them on a new file (rfgain.h) so we can later work on gain optimization functions * Update initial rf buffer settings and initial rf gain settings from HALs. This breaks things for now because our current dumps come from pre-configured rf buffer (regdumps already had the needed values set from binary HAL).

2009-01-29ath5k: honor the RTS/CTS bitsBob Copeland
The ath5k driver didn't use set_rts_threshold or use_cts_prot, and also didn't check the IEEE80211_TX_RC_USE_{RTS_CTS,CTS_PROTECT} RC flags.

2009-01-29ath5k: discard 11g caps if reported by an ar5211 eepromHelmut Schaa
At least one ar5211 card (GIGABYTE GN-WLMA101, 168c:0012 subsystem 1458:e800) reports itself as 11g capable which seems to be a bug in the eeprom. initvals.c assumes that ar5211 is only 11b capable and thus refuses to initialize this card. Hence this patch changes the probing for 11g capabilities to discard 11g capabilities for ar5211 cards which allows this specific card to work fine in 11b and 11a modes.

2009-01-29ath5k: More EEPROM code updatesNick Kossifidis
* Don't scale power values on RF5111 EEPROMs because they get out of bounds (power is u8, so multiplying power by 50 is too much and there is no reason to do so -we don't do it on other chips anyway-). HAL does it as a technique to handle 0.5 dbm steps but i believe it's not the right thing to do and certainly not the right place to do it.

2008-12-05ath5k: clean up ath5k_hw_set_keyBob Copeland
Status: O With the addition of TKIP (and soon CCMP), key->alg is a more useful guide to key type than the key length. This patch cleans up key type assignment in ath5k_hw_set_key by extracting it into its own function. It also replaces the separate memcpy() calls for extracting key material into the hardware format with a loop that works regardless of key size. Finally, the patch removes support for WEP-128 since it is a non-standard key length that mac80211 also doesn't use.

2008-11-21ath5k: ignore the return value of ath5k_hw_noise_floor_calibrationFelix Fietkau
Noise floor calibration occasionally fails on Atheros hardware. This is not fatal and can happen if there's simply too much noise on the air. Ignoring the calibration error is the right thing to do here, because when the error is ignored, the hardware will still work, whereas if the error causes the driver to bail out of a bigger configuration function and does not configure the tx queues or the IMR (as is the case in reset.c), the hw no longer works properly until the next reset.
