* ath5k: enable combined michael mic in key cacheBob Copeland2008-12-05
| | | | | | | | | | | | | | | | For mac revisions >= "Griffin," the hardware allows the mic tx and rx authenticator keys to share the same cache line, whereas earlier hardware can only store the rx. Enable the combined mic on hardware that supports it.

* ath5k: clean up ath5k_hw_set_keyBob Copeland2008-12-05
| | | | | | | | | | | | | | | | | | | 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.

* ath5k: preserve higher order bits when setting mac addressBob Copeland2008-12-05
| | | | | | | | | | | In some cases we would like to set the mac address without changing the operating mode. However, Atheros cards store PCU data in the high 16 bits of the mac address register. Change ath5k_hw_set_lladdr() to not clobber the PCU settings. Changes-licensed-under: ISC Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | *On a previous patch i splitted AR5K_INT_TX to multiple different TX interrupt flags for better handling but i forgot to unmask the new TXDESC and TXEOL interrupts on ath5k_init and only left TXOK. However for each queue we enable TXDESC and TXEOL interrupts, not TXOK so we don't handle TX interrupts at all (because these interrupts remain masked on PISR) and under load it results packet loss.

* | ath5k: ignore the return value of ath5k_hw_noise_floor_calibrationFelix Fietkau2008-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Also set TSF to 0 to start TSF increment on AP mode. We need to handle sleep timers for AR5212 there + add support for PCF. * Properly clean MIC key from keytable when TKIP is used (Bob is working on set_key function etc so i leave it for now).

* ath5k: HW code cleanupNick Kossifidis2008-09-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * No code changes... * Split hw.c to multiple files for better maintenance and add some documentation on each file code is going to grow soon (eeprom.c for example is going to get much stuff currently developed on ath_info) so it's better this way. * Rename following functions to maintain naming scheme: ah_setup_xtx_desc -> ah_setup_mrr_tx_desc (Because xtx doesn't say much, it's actually a multi-rate-retry tx descriptor) ath5k_hw_put_tx/rx_buf - > ath5k_hw_set_tx/rxdp ath5k_hw_get_tx/rx_buf -> ath5k_hw_get_tx/rxdp (We don't put any "buf" we set descriptor pointers on hw) ath5k_hw_tx_start -> ath5k_hw_start_tx_dma ath5k_hw_start_rx -> ath5k_hw_start_rx_dma ath5k_hw_stop_pcu_recv -> ath5k_hw_stop_rx_pcu (It's easier this way to identify them, we also have ath5k_hw_start_rx_pcu which completes the set) ath5k_hw_set_intr -> ath5k_hw_set_imr (As in get_isr we set imr here, not "intr") * Move ath5k_hw_setup_rx_desc on ah->ah_setup_rx_desc so we can include support for different rx descriptors in the future * Further cleanups so that checkpatch doesn't complain (only some > 80 col warnings for eeprom.h and reg.h as usual due to comments) Tested on 5211 and 5213 cards and works ok.

| * Ath5k: fix bintval setupJiri Slaby2008-08-26
| | | | | | | | | | | | | | | | | | | | | | bintval is set to the initial value at .config_interface which is too late, since it overwrites previously set value from .config. Move the initialization to the .add_interface. Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Cc: Nick Kossifidis <mickflemm@gmail.com> Cc: Luis R.

| * Ath5k: lock beaconsJiri Slaby2008-08-26
| | | | | | | | | | | | | | | | | | | | | | | | | | Beacons setup and config was racy with beacon send. Ensure that ISR and reset functions see consistent state of bbuf. Use also dev_kfree_skb_any in ath5k_txbuf_free since we call it from atomic now. Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Cc: Nick Kossifidis <mickflemm@gmail.com> Cc: Luis R.

* | ath5k: explicitly check skb->lenHarvey Harrison2008-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | ieee80211_get_hdrlen_from_skb internally checks that the skb is long enough to hold the full header, or it returns 0 if not. The check in ath5k does not check this case and assumes it always got the actual header length which it then checks against the skb->len plus some headroom. Change to ieee80211_hdrlen which always returns the hdrlen and keep the existing headroom check. Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: John W.

* | ath5k: rates cleanupBruno Randolf2008-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cleanup the rates structures used by ath5k. instead of separate driver and mac80211 rate structures we now setup a static ieee80211_rate array and use it directly. no conversion between two different rate structures has to be done any more. a lot of unused and confusing junk was deleted. renamed ath5k_getchannels into ath5k_setup_bands because this is what it does. rewrote it to copy the bitrates correctly for each band. this is necessary for running different hardware with the same driver (e.g. 5211 and 5212 based cards). add special handling of rates for AR5211 chipsets: it uses different rate codes for CCK rates (which are actually like the other chips but with a 0xF mask). setup a hardware code to rate index reverse mapping table for getting the rate index of received frames. the rates for control frames which have to be set in ath5k_hw_write_rate_duration are now in one single array. drivers/net/wireless/ath5k/ath5k.h: Changes-licensed-under: ISC drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD drivers/net/wireless/ath5k/base.h: Changes-licensed-under: 3-Clause-BSD drivers/net/wireless/ath5k/hw.c: Changes-licensed-under: ISC Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W.
