This iface is intended to be used with DEP transfers. It differs from pn533_send_cmd_async() in the way the response skb is allocated. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

This is intendend to replace pn533_send_cmd_frame_async() which requires from the caller to create a complete frame. The new function constructs a frame and sends it out which hides the frame logic and avoid code duplication. The caller has to allocate skb and put its payload there, and finally provide the skb together with a complete cb to pn533_send_cmd_async(). Response skb is allocated by the core part and pass to the caller cb. Next, the caller has to free it when is not needed anymore or pass it up to the stack.

__pn533_send_cmd_frame_async() is called when lock is held so GFP_KERNEL flag will be always used. Thus, having extra param does not optimise the code. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

This patch is an enhacement to mwifiex_pcie driver to use map/unmap PCI memory APIs. This reduces one memcpy each in TX path and RX path, and enhances throughput.

This patch uses pci_alloc_consistent and pci_free_consistent APIs for mwifiex_pcie driver. Consistent DMA memory is allocated for TX, RX and event rings. Command buffer and command response buffer also uses map/unmap memory APIs to download commands and get command responses.

This patch fixes a bug for few instances where PCIe interrupt status variable is accessed without holding spin lock. This can result into missing interrupts. Fix this by copying interrupt status to a local variable and then using it for calling specific routine.

The assignment of the IRQs to the cores of the chips by iterating over the cores is complicated and causes problems with SoC like the BCM4706 with two GMAC core where just one should get a dedicated IRQ number. Now the code assigns the same IRQs to the cores as the code from the Broadcom SDK does. If the SoC is not know the current assigned IRQs are only read out and an error message is printed.

TX_IQ_ON_AGC_CAL should not be enabled for AR9340. TX-IQ calibration is run as part of AGC calibration only for AR9485, AR9462 and AR9565. For the others (AR9300, AR9330, AR9340), TX-IQ cal is done independent of AGC-cal. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Currently, command path waits till all the tx host queues are empty. Whenever watchdog event is raised, firmware expects driver to destroy ampdu queues immediately. This requires corresponding commands i.e. mwl8k_cmd_get_watchdog_bitmap and mwl8k_destroy_ba to be sent without waiting for the tx queues to be completely empty. Use "watchdog_event_pending" to ensure the above mentioned two commands are sent down immediately.

With more ampdu streams, we need to handle watchdog events for the new ampdu streams. Handle these events appropriately. Earlier mwl8k_cmd_get_watchdog_bitmap used to return only one stream index and hence bitwise operations on the return value were not required. Now the function returns a bitmap with different bits are mapped with different stream indices.

Currently, mwl8k_ampdu_stream is passed as one of the argument to the function mwl8k_destroy_ba. Instead of this pass only the stream index.

If pci_set_dma_mask() or pci_set_consistent_dma_mask() fails in p54p_probe(), it breaks off initialization, deallocates all resources, but returns zero. Similar issue is if check for returned value of pci_resource_len() fails. The patch implements proper error code propagation. Found by Linux Driver Verification project (linuxtesting.org).
