The TX status reporting is done for both the nl80211 report as well as the socket option. The socket option is also reported when an skb is dropped to guarantee that the copy in the IDR tree is freed and status is reported to userspace. However, when a frame is dropped, no nl80211 status is reported. This can cause userspace to stop making progress while waiting for a status notification. Combine the nl80211 and socket option status reporting into a new function and call it in both places -- when the status comes in from the driver and when the skb is dropped. While at it, also simplify the code in the nl80211 portion a bit. Signed-off-by:Johannes Berg <johannes.berg@intel.com>

Just for debugging, print the interface TX power whenever it changes. Signed-off-by: -

Even before channel contexts/multi-channel, having a single global TX power limit was already problematic, in particular if two managed interfaces connected to two APs with different power constraints. The channel context introduction completely broke this though and in fact I had disabled TX power configuration there for drivers using channel contexts. Change everything to track TX power per interface so that different user settings and different channel maxima are treated correctly. Also continue tracking the global TX power though for compatibility with applications that attempt to configure the wiphy's TX power globally. Signed-off-by: -

The TX power setting is currently per wiphy (hardware device) but with multi-channel capabilities that doesn't make much sense any more. Allow drivers (and mac80211) to advertise support for per-interface TX power configuration. When the TX power is configured for the wiphy, the wdev will be NULL and the driver can still handle that, but when a wdev is given the TX power can be set only for that wdev now. Signed-off-by: -

Setting the wdev to NULL when the channel can't be set for that interface type (to treat the channel setting for the wiphy/monitor) currently works, but is confusing in the code if netdev/wdev aren't both set/unset in the same way. Move the check whether the channel can be set to where it's needed so that wdev and netdev are always both assigned or NULL. Signed-off-by: -

To use mac80211_hwsim for testing channel contexts it has to support them, and for that it has to support hw scan and hw-remain-on-channel. Since it's pure software, the off-channel activities are really not off-channel but listening and sending on a second channel. Also, the multi-channel isn't really doing TDM, it's just on both channels at the same time. For testing purposes, you can specify the number of concurrent channels with a module parameter, it is set to one by default. When set to two or more, the userspace API for wmediumd is disabled as it has no provisions for multi-channel yet. Signed-off-by: -

Whenever WLAN receives scheduling msg from BT, it reduces tx power based on RSSI level. And then BT starts simultaneous transmission along with WLAN. Sometimes HW MAC compares tx power that is used prior to power reduction which is causing BT transmission to defer. Signed-off-by:

This driver is for the AR5523 chipset from Atheros. It was created in 2007 by Christoph Hellwig but it was never finished. I found it a couple of months ago and after some polishing it's working pretty fine. The driver was written with the FreeBSD driver (uath) as reference, which was written with the reverse-engineered windows driver as reference, hence the feature set is very limited. Station mode only, no HW crypto offload. Signed-off-by:

For AP feature the IEs are stored in global structure. For future functionality like P2P-GO it needs to be stored per virtual interface so better store it in the virtual interface structure. Reviewed-by:

The functions for communicating were given the net_device only because its private data contained struct brcmf_if object. However, not all firmware related interfaces will be associated with a net_device. To accomodate provisioning firmware for such interfaces the struct brcmf_if object will be passed to the fwil functions. Reviewed-by:

When the firmware notifies the driver about adding a new interface it also provides an index for the bss associated with this interface. This index will be needed for upcoming features like peer-to-peer. By adding this index in struct brcmf_if it is easy to obtain as this will be associated with the net_device private data.
