Currently, RSI_NEEDED_HEADROOM is '80' for rsi driver, which is wrong. As per rsi internal frame format, the RSI_NEEDED_HEADROOM shall be '84', which is 64(dword_align) + 4(extended_desc) + 16(frame_desc). Hence, corrected the needed headroom.

2018-07-31rsi: add firmware support for AP+BT dual modeSiva Rebbagondla1-0/+3
Currently, AP mode will work on only WLAN alone firmware. To give support for AP and BT dual mode, adding firmware entry in 'struct ta_metadata'. The firmware entry is based on what coex_mode is used in driver and coex mode '4' for all AP+BT related functionalities. Hence, added the same.

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.

2018-07-31mwifiex: use atomic bitops to represent adapter status variablesGanapathi Bhat15-72/+91
Driver is using boolean variables to maintain vairous status information of adapter. These status variables are accessed by multiple threads and there is a possibility of a race. To avoid this, convert these variables to a set of bitops flags, to be operated atomically. Below variables of mwifiex_adapter are converted to bitop flags: surprise_removed is_cmd_timedout is_suspended is_hs_configured hs_enabling Signed-off-by: Ganapathi Bhat <gbhat@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-07-31mwifiex: restructure rx_reorder_tbl_lock usageGanapathi Bhat3-51/+53
Driver must ensure that whenever it holds a pointer to the list entry mwifiex_rx_reorder_tbl, it must protect the same with rx_reorder_tbl_lock. At present there are many places where driver does not ensure this. To cover all cases, spinlocks in below funcions are moved out and made sure that the caller will hold the spinlock: mwifiex_11n_dispatch_pkt_until_start_win() mwifiex_11n_scan_and_dispatch() mwifiex_del_rx_reorder_entry() mwifiex_11n_get_rx_reorder_tbl() mwifiex_11n_find_last_seq_num() Signed-off-by: Ganapathi Bhat <gbhat@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-07-31mwifiex: replace rx_pkt_lock by rx_reorder_tbl_lockGanapathi Bhat3-13/+10
At present driver spinlock protects iteration of list rx_reorder_tbl_ptr with rx_reorder_tbl_lock. To protect the individual items in this list, it uses rx_pkt_lock. But, we can use a single rx_reorder_tbl_lock for both purposes. This patch replaces rx_pkt_lock by rx_reorder_tbl_lock.

2018-07-26iwlwifi: introduce new rx structures used by 22560 RFHGolan Ben Ami1-0/+100
22560 devices RFH uses different structures, which act similar to the legacy rxq management lists - free and used list. The iwl_rx_transfer_desc struct is part of the free list, and consists of pointers to the empty rb's the driver wants to pass to the fw. The iwl_rx_completion_desc struct is part of the used list, and consists of pointers to the buffer the fw filled up with new rx, both commands and data, for the host.

2018-07-26iwlwifi: cancel the injective function between hw pointers to tfd entry indexGolan Ben Ami2-7/+16
Nowadays, the tfd queue max size is 2^8, and the reserved size in the command header sequence field for the tfd entry index is 8 bits, allowing an injective function from the hw pointers to the tfd entry index in the sequence field. In 22560 devices the tfd queue max size is 2^16, meaning that the hw pointers are 16 bit long (allowing to point to each entry in the tfd queue). However, the reserved space in the sequence field for the tfd entry doesn't change, and we are limited to 8 bit. This requires cancelling the injective function from hw pointer to tfd entry in the sequence number. Use iwl_pcie_get_cmd_index to wrap the hw pointer's to the n_window size, which is maximum 256 in tx queues, and so, keep the injective function between the window wrapped hw pointers to tfd entry index in the sequence.

2018-07-26iwlwifi: pcie: support context information for 22560 devicesGolan Ben Ami7-60/+578
Context information structure was added to 22000 devices for firmware self init. In the next generation of devices the context information changes significantly, and the original context information is divided roughly to three data structures: context information gen3, prph information and prph scratch. In addition, the init flow changes so the firmware is loaded by the IML, and so we must allocate the IML on the DRAM and give the ROM the IML's address before kicking the firmware's self init.

2018-07-26iwlwifi: pcie: allocate and free rx cr's and tr's tailsGolan Ben Ami2-83/+131
The hw now refers to two new blocks: * rx tr tail - The Tail index on the free buffers queue TR, which is update by the device after reading the free buffer from the tr. * rx cr tail - Updated by the driver when completing processing a new completion descriptor in the cr. Add these two new struct to the rxq, allocate and free them when needed. In addition, the register for rx write pointer had been changed to HBUS_TARG_WRPTR. The way to differentiate tx from rx is the queue number. TX range is 0-511, and RX's is 512-527.
