ah->noise is maintained globally and not per-channel. This is updated in the reset() routine after the NF history has been filled for the *current channel*, just before switching to the new channel. There is no need to do it inside getnf(), since ah->noise must contain a value for the new channel. Cc: stable@vger.kernel.org Signed-off-by:

The commits, "ath9k: Fix regression in channelwidth switch at the same channel" "ath9k: Fix invalid noisefloor reading due to channel update" attempted to fix noisefloor calibration when a channel switch happens due to HT20/HT40 bandwidth change. This is causing invalid readings resulting in messages like: "ath: phy16: NF[0] (-45) > MAX (-95), correcting to MAX". This results in an incorrect noise being used initially for reporting the signal level of received packets, until NF calibration is done and the history buffer is updated via the ANI timer, which happens much later. When a bandwidth change happens, it is appropriate to reset the internal history data for the channel. Do this correctly in the reset() routine by checking the "chanmode" variable.

When b43 gets build into the kernel and it should use bcma we have to ensure that bcma was also build into the kernel and not as a module. In this patch this is also done for SSB, although you can not build b43 without ssb support for now. This fixes a build problem reported by Randy Dunlap in 5187EB95.2060605@infradead.org Reported-By:

All known ar7010+ar* device and current FW support STBC TX. This patch make use of it and suggest to send STBC if peer support it. I use wort "suggest" since currenly we have separate rate controller in FW which will make decision based on rate and hardware. Signed-off-by:

WMI PCP Start flow should not be handled through: net_device_ops->ndo_open()->wil_up()->__wil_up() because it missing mandatory FW parameters (SSID,Channel,IEs, Security...). Prior to AP starting __wil_up() may be called with iftype set cfg80211_ops->change_virtual_intf(NL80211_IFTYPE_AP or STATION) depend on the application hostapd/wpa_supplicant/iw. there should not be an attempt to start an AP flow, AP/PCP start flow will be started latter by cfg80211_ops->start_ap().

The CAB (Content after Beacon) queue is used for beacon-triggered transmission of buffered multicast frames. If lots of multicast frames were buffered and this queue fills up, it drowns out all regular traffic. To limit the damage that buffered traffic can do, try to limit the queued data to becaon_interval / 8. Signed-off-by:

When initialization within brcmf_bus_start() fails on steps before the brcmf_net_attach() the net_device for the primary interface needs to be freed. This patch resolves a panic during kernel boot as reported by Stephen Warren. ref.: http://mid.gmane.org/51AD1F22.2080004@wwwdotorg.orgTested-by:

When data is available and fw signalling is enabled then TIM information should be sent to firmware. If it can piggy back on existing packet then do that otherwise create dummy packet to get information out. Cc: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by:

Currently suppressed packets get enque-ed with header which then gets pulled before transmit. It is more logical and clean to pull the header on return and push it unconditionally on xmit. Reviewed-by:

During P2P testing it turned out that the firmware sents multiple multiple creditmap event messages. Only the first message from the firmware should be processed. Otherwise the firmware-signalled flow control can run haywire when it has packets outstanding in firmware. Reviewed-by:

On bus flow control (no more host bus resources to send packets to device) the netif flow control was toggled, however credit management should also take this status into account. Since there are multiple sources handling this flow control necessary spinlocks were added to protect flow control related data/states. Reviewed-by:

The extra_tx_headroom field of struct rt2x00_ops indicates the extra TX headroom size required for a given device. This data is redundant, the value can be computed from the desc_size and winfo_size fields of the TX queues. Move the extra_tx_headroom field to struct rt2x00_dev, compute its value in the probe routine and use the cached value in the rest of the code. Signed-off-by:
