2019-02-08rsi: fix for wowlan wakeup failureSiva Rebbagondla
During wowlan regression tests, sometimes radio is not waking up for wowlan packet in coex mode. This is because of power save is enabled by default in case of coex mode greater than one. Hence, disable power save in coex mode to avoid radio loss. Signed-off-by: Siva Rebbagondla <siva.rebbagondla@redpinesignals.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-02-08rsi: resolve power save issue after S4 resumeSiva Rebbagondla
We are redownloading the firmware after S4 restore and observed in stress test that mac80211 sometimes gives power save request after resume which causes the firmware in bad state. mac_ops_resumed flag is added to skip that request until initialisation is done and Keeping power save state is NONE.

2019-01-10rsi: add support for hardware scan offloadPrameela Rani Garnepudi
With the current approach of scanning, roaming delays are observed. Firmware has support for back ground scanning. To get this advantage, mac80211 hardware scan is implemented, which decides type of scan to do based on connected state. When station is in not connected, driver returns with special value 1 to trigger software scan in mac80211. In case of connected state, background scan will be triggered.

2018-07-31rsi: optimize virtual interfacesSiva Rebbagondla
Due to multiple calls of add interface routine, vif is getting duplicated and at certain instance, we are out of vifs, causing the driver to behave abnormal. Fix: Every vif has a unique mac-id, when we got a vif with same mac-id as the previous id's, we will override the respective vif.

2018-05-23rsi: add fix for crash during assertionsSanjay Konduri
Observed crash in some scenarios when assertion has occurred, this is because hw structure is freed and is tried to get accessed in some functions where null check is already present.

2018-05-15rsi: Add null check for virtual interfaces in wowlan configSanjay Kumar Konduri
When the "poweroff" command is executed after wowlan enabled, we have observed a system crash. In the system "poweroff" sequence, network-manager is sent to inactive state by cleaning up the network interfaces, using rsi_mac80211_remove_interface() and when driver tries to access those network interfaces in rsi_wowlan_config() which was invoked by SDIO shutdown, results in a crash. Added a NULL check before accessing the network interfaces in rsi_wowlan_config().

2018-04-24rsi: roaming enhancementsPrameela Rani Garnepudi
To support roaming below changes are done: * Station notify frame is send to firmware after sending assoc request. This will avoid dropping of first EAPOL frame due to delay in creation of station control block in firmware. * Data queues are unblocked after sending station notify in open mode, after configuring key in WEP mode, and after receiving EAPOL4 confirm in WPA mode. * Initial EAPOL frames priority is chaged to MGMT, rekey EAPOL frames priority changed to VO.
