| * ath6kl: Maintain the listen interval per VIF specificRaja Mani2012-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Firmware has the option to support the listen interval per vif specific. Fix this. Listen interval can be set by the TUs or by the number of beacons. Current code enables the user to configure the listen interval in the unit of 'number of beacons' using debugfs entry "listen_interval". Going forward, we need to alter the listen interval in the unit of TUs to get good power numbers while going to WOW suspend/resume. Allowing the user to change the listen interval in the unit of "number of beacons" in debugfs and changing listen interval in wow suspend/resume in the unit of time (TUs) would lead us to confuse. This patch make sures the listen interval is changed only in the unit of time (TUs). Signed-off-by: Raja Mani <rmani@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Below two scenarios are taken care in this patch which helped to fix the firmware crash during wow suspend/resume. * TX operation (ctrl tx and data tx) has to be controlled based on suspend state. i.e, with respect to WOW mode, control packets are allowed to send from the host until the suspend state goes ATH6KL_STATE_WOW and the data packets are allowed until WOW suspend operation starts. * Similarly, wow resume is NOT allowed if WOW suspend is in progress.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It gives flexibility to the user to define suspend policy when the suspend mode is set to WOW and the device is in disconnected state at the time of suspend. New module parameter wow_mode is added to get the choice from the user. This parameter is valid only if the module parameter suspend_mode is set to WOW. To force WOW in connected state and cut power in disconnected state: suspend_mode=0x3 wow_mode=0x1 To force WOW in connected state and deep sleep in disconnected state (this is also the default wow_mode): suspend_mode=0x3 wow_mode=0x2 If there is no value specified to wow_mode during insmod, deep sleep mode will be tried in the disconnected state. kvalo: clarified commit log Signed-off-by: Raja Mani <rmani@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| * | ath6kl: assign Tx packet drop threshold per endpoint based on AC priorityChilam Ng2012-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tx packets will begin to drop when there are multiple traffic priorities and the current traffic is not the highest priority and the remaining cookies drop below a certain number, which is fixed for all AC. It is possilbe that lower priority AC have more traffic which will consume more cookies and lock out higher priority AC from having any. Assign each endpoint (AC) with a different Tx-packet-drop threshold so lower priority AC is more likely to drop packets and the cookies become more available to higher priority AC.

| * | ath6kl: Add unicast mgmt frame bufferingNaveen Gangadharan2012-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PS buffering of unicast Action frames that are sent in a context of a BSS. In AP mode when the recepient station goes to powersave and PS_POLL flag is not set, we would buffer the frames. Send out unicast mgmt bufferred frame when PS_POLL is received. This fixes a bug in P2P GO behavior when sending a GO Discoverability Request to a client that is in sleep mode. kvalo: indentation fixes Signed-off-by: Thirumalai Pachamuthu <tpachamu@qca.qualcomm.com> Signed-off-by: Naveen Gangadharan <ngangadh@qca.qualcomm.com> Signed-off-by: Aarthi Thiruvengadam <athiruve@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| * | ath6kl: prioritize Tx bundling based on AC prioritiesChilam Ng2012-02-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tx bundling is the more efficient use of SDIO bus and allows more packet transfers with fewer bus transactions, and is a way to improve overall throughput. However, Tx bundling has only 4 scatter request resources available. When there are multiple traffic streams of different priorities, it's possible that lower priority traffic may hog all the scatter requests and lock out the higher prioirty traffic from bundling. Tx bundling is now enabled per AC. When an AC do a scatter request and the remaining scatter request resources is lower than a configurable threshold, it will disable Tx bundling for all AC's of lower priorities. When an AC has Tx bundling disabled and has no Tx bundles sent in a consecutive and configurable number of packets, Tx bundling will be re-enabled for that AC.
