The function rsi_mgmt_pkt_to_core() is for passing the 802.11 management frames to mac80211. So, it is unnecessary to check again for the frame type 802.11 management in this function. It can be checked before passing to this function. Signed-off-by:

Radio capabilities frame is updated to use common descriptor structure. Also, few changes to this frame is done like hardware queues are increase to 12 from 8, default channel number is included. Signed-off-by:

For all TX command packets immediate wakeup bit needs to be set in descriptor. This will make sure device will wakeup if it is in any sleep state. Priority of the packet is also set. Signed-off-by:

All internal management packets (command packets) use some common fields and some packet specific fields for packet descriptors. This patch adds some common structures which are needed for all command packets. Signed-off-by:

Deadlock issue is observed during our stress tests. The root cause for the issue is same lock is used between tx and rx threads. This patch adds a separate mutex lock for rx thread to resolve the problem. Signed-off-by:

Newer firmware sends information about number of blocks through interrupt only. We don't need to read extra register for this. This patch adds needed driver changes for this enhancment. The change here is backward compatible Signed-off-by:

SDIO host is already claimed in our interrupt handler. Some lower level APIs claims host while performing SDIO read or write operations. Let's use sdio_irq_task variable to check if we are in interrupt context and claim/release the host accordingly. Signed-off-by:
-

The variable in_sdio_litefi_irq is renamed to sdio_irq_task, as it is more relevant here. Signed-off-by:

Sometimes it's observed that we get interrupt/Rx frame when device is already detached from mac80211. In this case couple of error messages are displayed in dmesg log. This patch corrects the order so that disconnection will happen cleanly Signed-off-by:

EEPROM read frame is sent during device initialization to read mac address. The format of the frame is modified in firmware to include eeprom length and offset. This frame does not return firmware version now. Also same frame is sent again to read rf type and band information. Signed-off-by:

Whenever new fsm_state enum element is added, fsm_state array also needs to be updated. If this change is missed, we may end up doing invalid access in array. BUILD_BUG_ON check will help to avoid this problem. Signed-off-by:
