2014-03-17brcmfmac: remove mode field from brcmf_cfg80211_vif structureArend van Spriel
The nl80211 iftype was converted to a mode value and stored in brcmf_cfg80211_vif structure. The value was used only within brcmfmac driver to decide execution of conditional code. Better use wireless_dev::iftype for that as the wdev is contained in the brcmf_cfg80211_vif structure.

2014-03-17brcmfmac: assure active clock request upon entering SLEEP stateArend van Spriel
When the SDIO driver goes in low power state it must assure that a clock request in ChipCLKCSR is set. Otherwise waking up the device can fail. The register is read and if necessary the ALP clock will be requested.

2014-03-17brcmfmac: Improve scanning settings for connect.Hante Meuleman
When connecting without specifying the channel it can take quite some time to connect. This is because not all parameters for the scan operation are set to optimized values. This patch changes these parameters resulting in a much faster connect in certain situations.

2014-03-17brcmfmac: Protect tx seq number for data and controlHante Meuleman
SDIO tx uses a sequence number which is common for data and control. This requires that access to this sequence number is protected. A mutex was used to achieve this, but it also required the reordering of code for tx control.

2014-03-14ath9k_hw: set ANI firstep as absolute values instead of relativeFelix Fietkau
On older chips, the INI value differ in similar ways as cycpwr_thr1, so convert it to absolute values as well. Since the ANI algorithm is different here compared to the old implementation (fewer steps, controlled at a different point in time), it makes sense to use values similar to what would be applied for newer chips, just without relying on INI defaults.

2014-03-14ath9k_hw: set ANI cycpwr_thr1 as absolute values instead of relativeFelix Fietkau
The table was copied from the ANI implementation of AR9300. It assumes that the INI values contain a baseline value that is usable as reference from which to increase/decrease based on the noise immunity value. On older chips, the differences are bigger and especially AR5008/AR9001 are configured to much more sensitive values than what is useful. Improve ANI behavior by reverting to the absolute values used in the previous implementation (expressed as a simple formula instead of the old table).

2014-03-14rtl8180: prepare to handle more than two chip typesAndrea Merello
Currently a "r8185" integer variable is used as a boolean flag to indicate whether the card is a rtl8185 or not. Since now the driver supports only rtl8185 and rtl8180 cards, if "r8185" variable is zero then the card is implicitly assumed to be a rtl8180. Now I'm preparing to add support for a third card type (rtl8187se). This patch changes the "r8185" flag with an enum variable to explicitly indicate which card type we have. I'm submitting this this patch now, even if I still have to submit other patches that not pertain with rtl8187se support, because IMHO it's not worth rebasing them on the current code, using r8185 flag, and then changing them back again nearly immediately.
