| * mwifiex: recover from skb allocation failures during RXZhaoyang Liu2015-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds recovery mechanism for SDIO RX during SKB allocation failures. For allocation failures during multiport aggregation, we skip and drop RX packets. For single port read case, we will use preallocated card->mpa_rx.buf to complete cmd53 read. Now we terminate SDIO operations only upon cmd53 failures.

| * mwifiex: Fix issue in the SDIO reset path of mwifiex.Maithili Hinge2015-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | SDIO reset was not happening properly on mwifiex as cancel_work_sync in mwifiex_sdio_remove used to kill the calling work function itself. Due to this, the interface was not getting removed and card was not getting added again. Reset work function has been made independent of adapter variable and cancel_work_sync has been moved to cleanup function.

| * mwifiex: add SDIO rx single port aggregationZhaoyang Liu2015-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| * cfg80211: add bss_type and privacy arguments in cfg80211_get_bss()Dedy Lansky2015-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 802.11ad adds new a network type (PBSS) and changes the capability field interpretation for the DMG (60G) band. The same 2 bits that were interpreted as "ESS" and "IBSS" before are re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid values are: "IBSS", "PBSS" (new) and "AP". 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.) The remaining bits in "capa_mask" and "capa_val" are used only for privacy matching so replace those two with a privacy enum as well.

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.

* mwifiex: update IEs after AP has startedAvinash Patil2015-01-29
| | | | | | | | | | This patch moves IE management routine to end of start_ap handler. IEs now would be updated after AP has started.

* mwifiex: do not send regulatory update while starting APAvinash Patil2015-01-29
| | | | | | | | | | | When regulatory domain changes, cfg80211 already issues request to change regulatory domain to driver via reg_notifier. There is no need to set regulatory again during start_ap.

* mwifiex: support conversion to any virtual interface typeAvinash Patil2015-01-29
| | | | | | | | | | | | Currently, we support virtual interface type change from station<=>adhoc or station <=> p2p client/GO. This patch adds support to change virtual interface type to any of the type advertised in interface combinations.

* mwifiex: manage virtual interface limits efficientlyAvinash Patil2015-01-29
| | | | | | | | | | | | | | Currently interface limits are checked by seeing if bss_mode for particular priv is set. If bss_mode is not set, interface creation is allowed. This patch adds framework to initializes maximum virtual interfaces supported during load time and check current number of interfaces created agains allowed interface limit during new virtual interface creation.

* mwifiex: add init parameter to init command routineAvinash Patil2015-01-29
| | | | | | | | | | | | | FW initialization routine can also be called while changing virtual interface types. This patch adds bool parameter "init" to init command routine so as to differentiate between initialization during driver load and change virtual interface handler.
