2013-12-02brcmfmac: add separate function for passing bus tx overheadArend van Spriel
The common driver needs the packet overhead for the bus in order to reserve headroom for sk_buffs. For the SDIO driver this depends on firmware features so it is not possible to provide it in the brcmf_attach() call.

2013-12-02brcmfmac: Update fwsignal to fix out of order tx.Hante Meuleman
When using fwsignal it is possible that tx packets get delivered out of order. This patch fixes that by reordering suppressed packets and tracking generation bit and sequence number per packet.

2013-12-02ath9k_hw: allow fast channel change when only CHANNEL_HT changesFelix Fietkau
The CHANNEL_HT flag is insignificant for fast channel change conditions, since it does not affect any important part of the hardware reset / channel setup. Scanning usually runs with HT disabled, so this change will slightly improve scan time on many chipsets. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-12-02ath9k_hw: fix TSF save/restore around chip resetFelix Fietkau
A cold reset can be triggered because of DMA stop issues, and this leads to TSF being cleared on all chipsets. To properly deal with this, always save the TSF. Additionally, account for the time it takes to do the actual chip reset, which can be quite significant. On AR9344 it takes around 4.5 ms.

2013-12-02ath9k: use a timer to put hardware into full sleepFelix Fietkau
When operating in client mode, the short period of time between scanning and associating is often enough to put the hardware through several FULL-SLEEP <-> AWAKE transitions, each wakeup requiring a reset to fully recover the hardware. This is completely unnecessary and can easily be avoided by deferring the switch to full sleep. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2013-12-02ath9k: Separate routines for PCOEM and SoC calibrationSujith Manoharan
Though there is some overlap between the calibration mechanisms of PC-OEM cards and SoC chip families, dumping both of them into a single function makes things hard to understand. ar9003_hw_init_cal() is unreadable with chip-specific segments scattered around. To make the logic understandable, use different functions for client cards and SoC chips. Some code is duplicated, but in the long run, it makes the code more maintanable.

2013-12-02ath9k: Fix TX99 config option usageSujith Manoharan
Use CONFIG_ATH9K_TX99 to properly enclose the tx99 code and make sure that it is not compiled as part of the driver when it is not selected. Move the tx99 code to a new file tx99.c and also add ATH9K_DEBUGFS as a dependency in Kconfig. This reduces the module size on platforms like OpenWrt where ATH9K_DEBUGFS is selected, but TX99 might be disabled. Cc: Luis R.
