The check after the loop which checks whether the initialization timed-out was wrong. If the initialization would succeed exactly in the 20000th time (the value set for INIT_LOOP), the driver would bail out and claim that initialization failed.

When mac80211 is asked to buffer multicast frames in AP mode, it will not set the flag indicating that the frames should be sent after the DTIM beacon for those frames buffered in software. Fix this little inconsistency by always setting that flag in the buffering code path. Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W.

This value is unused by mac80211, because it was only be used by wireless extensions, and turned out to not be useful there because the quality value needs to be comparable between scan results and the current value which is impossible when the qual value is calculated taking into account noise, for example. Since it is unused anyway, this patch deprecates it in the hope that drivers will remove their sometimes quite expensive calculations of the value. I'm open to actual uses of the value, but the best way of using it seems to be what the Intel drivers do which should probably be generalised if we have noise values from the hardware.

Compared to ieee80211_beacon_get(), the new function ieee80211_beacon_get_tim() returns information on the location and length of the TIM IE, which some drivers need in order to generate the TIM on the device. The old function, ieee80211_beacon_get(), becomes a small static inline wrapper around the new one to not break all drivers.

Force bias is a fix for usage of AR5416 radios on the 2.4 GHz band for orientation sensitivity. This was only partially implemented with the ath9k_hw_decrease_chain_power() but first -- this was being called for all chipsets which is not correct and second -- it was missing the actual orientation code. We now ensure to only enable force bias only for AR5416 and BUG_ON() on other chipsets. Although ath9k_hw_decrease_chain_power() was enabled for newer chipsets I suspect that it never ran unless the EEPROM had ATH9K_ANT_FIXED_A or ATH9K_ANT_FIXED_B for antenna diversity.

ath9k_hw_rfattach() was just calling a helper and this helper was doing nothing for single-chip devices, and for non single-chip devices it is just allocating memory for banks to program the RF registers at a later time. Simplify this by having the hw initialization call the rf bank allocation directly for external radios. Also, propagate an -ENOMEM properly now upon failure. Signed-off-by: NLuis R.

Document what we can about the RF analog front ends (radios) of Atheros 802.11n devices. What should be clearer now is the what we do for old pre AR5416 and AR5418 MAC based devices in comparison to the modern sigle-chip 802.11n solutions. All devices after AR9280 are single chip and require less programming -- the RF registers no longer need to be initialized as they all have the RF analog front end embedded together with the MAC/BB; this includes the AR9271. Older devices such as the ones with the AR5416 MACs (PCI) or AR5418 MACs (PCI-E) have an external 2.4 GHz AR2133 radio or a dual band 2.4 GHz / 5 GHz AR5133 radio. These external radios require additional programming of the RF registers. Clarify which parts are for what devices and which code is shared. This patch has no functional changes.

This update the register initialization/reset values (aka initvals) for ar9271 based on the last recommended values on 2009-06-04 by our systems engineering team. The changes account for: * Supporting ar9271 1.0 and ar9271 1.1 together, the difference is bb_spectral_scan_ena, for 1.0 we'll set this to 0x1. * Ensuring we get the correct noise floor values -115 ~ -118 when we enable bb_enable_ant_div_lnadiv=0 and mc_tx_def_ant_sel=1. Previous to this we would get noise floor values in the range -50 ~ -80. To fix settings for the registers: - bb_ch1_xatten1_db - bb_ch1_xatten2_db - bb_ch1_xatten1_margin - bb_ch1_xatten2_margin - bb_ch1_gain_force - bb_ch1_xatten2_hyst_margin - bb_ch1_xatten1_hyst_margin - bb_ch1_max_oc_gain * 0x8120[2] mc_mic_new_location_enable is changed to 0x1. The MAC team suggest to set this value. * 0x9910[0] bb_spectral_scan_ena is changed to 0x0. For ar9271 1.1 we don't need to enable this bit.

While there may be a case for a driver adding its own bits of radiotap information, none currently does. Also, drivers would have to copy the code to generate the radiotap bits that now mac80211 generates. If some driver in the future needs to add some driver-specific information I'd expect that to be in a radiotap vendor namespace and we can add a different way of passing such data up and having mac80211 include it. Additionally, rename IEEE80211_CONF_RADIOTAP to IEEE80211_CONF_MONITOR since it's still used by b43(legacy) to obtain per-frame timestamps. The purpose of this patch is to simplify the RX code in mac80211 to make it easier to add paged skb support. Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W.

In commit 601ae7f2 Author: Bruno Randolf <br1@einfach.org> Date: Thu May 8 19:22:43 2008 +0200 mac80211: make rx radiotap header more flexible code was added that tried to align the radiotap header position in memory based on the radiotap header length. Quite obviously, that is completely useless. Instead of trying to do that, use unaligned accesses to generate the radiotap header. To properly do that, we also need to mark struct ieee80211_radiotap_header packed, but that is fine since it's already packed (and it should be marked packed anyway since its a wire format).

There's currently a very odd bug in mac80211 -- a hardware scan that is done while the hardware is really operating on 2.4 GHz will include CCK rates in the probe request frame, even on 5 GHz (if the driver uses the mac80211 IEs). Vice versa, if the hardware is operating on 5 GHz the 2.4 GHz probe requests will not include CCK rates even though they should. Fix this by splitting up cfg80211 scan requests by band -- recalculating the IEs every time -- and requesting only per-band scans from the driver. Apparently this bug hasn't been a problem yet, but it is imaginable that some older access points get confused if confronted with such behaviour.
