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:

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. Signed-off-by:

We adjust the core clock for ar9271 to 117 MHz; this also requires us to adjust the baud divider based on the targetted baud rate. Signed-off-by:

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.

Move the netwave driver to drivers/staging. This is another pre-802.11 driver that has seen virtually no non-API-fixup activity in years, and for which no active hardware is likely to still exist. This driver represents unnecessary ongoing maintenance for no clear benefit. This patch brought to you by the "hacking" session at the 2009 Kernel Summit in Tokyo, Japan... Acked-by:

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:

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. Signed-off-by:

We had 0x9912 but AR_PHY_SPECTRAL_SCAN is 0x9910. By using the 0x9912 we were making the hardware unresponsive. This allows us to move forward with hardware reset on ar9271 on the ath9k_htc driver. Signed-off-by:

Devices with external radios have revisions which we can count on. On single chip solutions these EEPROM values for these radio revision also exist but are not meaningful as the radios are embedded onto the same chip. Each single-chip device evolves together as one device. Signed-off-by:

wl1251 supports power save and it can be enabled now. Signed-off-by:

In TX path it was assumed that dynamic power save works only if IEEE80211_HW_PS_NULLFUNC_STACK is set. But is not the case, there are devices which have nullfunc support in hardware but need mac80211 to handle dynamic power save timers, TI's wl1251 is one of them. The fix is to not check for IEEE80211_HW_PS_NULLFUNC_STACK in is_dynamic_ps_enabled(), instead check IEEE80211_HW_SUPPORTS_PS and IEEE80211_HW_SUPPORTS_DYNAMIC_PS flags and act accordingly. Tested with wl1251. Signed-off-by:

We can save a lot of code and pointers in the structs by using debugfs_remove_recursive(). First, change cfg80211 to use debugfs_remove_recursive() so that drivers do not need to clean up any files they added to the per-wiphy debugfs (if and only if they are ok to be accessed until after wiphy_unregister!). Then also make mac80211 use debugfs_remove_recursive() where necessary -- it need not remove per-wiphy files as cfg80211 now removes those, but netdev etc. files still need to be handled but can now be removed without needing struct dentry pointers to all of them.

The temporary copy of the VLAN group is not neccessary since the lower device is already in the process of being unregistered, if it was neccessary the memset of the global group would introduce a race condition. With this removed, the changes to the original code are only a few lines, so remove the new function and move the code back into vlan_device_event(). Signed-off-by:
