2015-05-26cfg80211: properly send NL80211_ATTR_DISCONNECTED_BY_AP in disconnectJohannes Berg
When we disconnect from the AP, drivers call cfg80211_disconnect(). This doesn't know whether the disconnection was initiated locally or by the AP though, which can cause problems with the supplicant, for example with WPS. This issue obviously doesn't show up with any mac80211 based driver since mac80211 doesn't call this function. Fix this by requiring drivers to indicate whether the disconnect is locally generated or not. I've tried to update the drivers, but may not have gotten the values correct, and some drivers may currently not be able to report correct values. In case of doubt I left it at false, which is the current behaviour. For libertas, make adjustments as indicated by Dan Williams.

This will expose in /sys whether the ifname of a device is set by userspace or generated by the kernel. The latter kind (wlanX, etc) is not deterministic, so userspace needs to rename these devices to names that are guaranteed to stay the same between reboots. The former, however should never be renamed, so userspace needs to be able to reliably tell the difference.

2015-03-16mwifiex: add SDIO rx single port aggregationZhaoyang Liu
This patch brings in support for SDIO single port rx aggregation to mwifiex. Maximum read size support by SDIO cmd53 is 64K. Based on multi port aggregation which is already part of mwifiex, idea here is multiple packets received in FW can be aggregated into single buffer. A separate upload type is defined for such packet aggregated to single port. Packets from this single buffer are later deaggregated into individual packets. This way, driver can receive more packets each time through single SDIO cmd53; thereby reducing no of times MMC bus is accessed. SDIO SP aggregation support is advertised by FW during load time and driver would get FW block size in command response of HostCmd_CMD_SDIO_SP_RX_AGGR_CFG.

802.11ad adds new a network type (PBSS) and changes the capability field interpretation for the DMG (60G) band.

In order to get the BSS struct for the new PBSS networks, change the cfg80211_get_bss() function to take a new enum ieee80211_bss_type argument with the valid network types, as "capa_mask" and "capa_val" no longer work correctly (the search must be band-aware now.)

2015-02-27mwifiex: more_task flag for main_processShengzhen Li
This patch handles a corner case where TX packet would remain in driver queue till next packet comes in. Here is sequence: 1. TX packet is queued via hard_start_xmit and main_work is queued 2. SDIO interrupt comes in which directly call mwifiex_main_process. This starts executing main superloop. 3. Now work from step1 is scheduled but at first check itself it sees mwifiex_processing is set and exits. 4. Now if superloop from step2 has passed TX processing part of superloop this packet would remain in queue until next packet/command/SDIO interrupt arrives and queues main_work. This patch fixes this corner case by defining more_task flag which is set when mwifiex_processing is found to be true. At end of superloop we again check if more_task flag is set and if set, execute superloop again.
