Some of the key differences between SD8897 and older chipsets are as follows: a) sdio mpa_rx and mpa_tx ports have been increased from 16 to 32 b) Same is the case with read/write bitmap that one receives from mpa_reg read c) aggregation packet count doubled from 8 to 16 d) Most of key reg addresses are changed e) There is a separate command or control port f) Now command rx/tx_done have new interrupts 1. 'supports_sdio_new_mode' flag is added to handle (a) and (b). 2. (c) and (d) are taken care of by filling chip specific information in global structurei (mwifiex_sdio_sd8897). 3. For older chipsets, port 0 was cmd port and port 1->15 were data port. Therefore we had CTRL_PORT_MASK to differentiate port type. Now these changes are under 'has_control_mask' flag. Signed-off-by:

There are some macros defined for multiport aggregation calculations. As we may need to add some more code to accomodate new chipsets, we will change them to inline functions. Also, use dynamic allocation for Rx buffer array. Signed-off-by:

We see this WARN_ON during PCIe unload: WARNING: at kernel/smp.c:382 smp_call_function_many+0x66/0x1e1() This happens because we are doing PCI iounmap operations while holding spinlock via spin_lock_irqsave(). Holding spinlock this way causes disabling IRQs and hence PCI iounmap shows warning on irqs_disabled() check. Use non-irq variant of spin_lock i.e. spin_lock() instead. Signed-off-by:

This patch adds cfg80211 del_station handler for mwifiex. If bss is not started or there are no stations in associated stations list, no action is taken. If argument received is null/broadcast mac, all stations in associated station list are deauthenticated. Patch also deletes related RxReorder stream and TxBA stream tables for related station.

During deleting a station entry from associated sta_list, we are supposed to delete entry only for this particular mac address. This patch is a bug fix wherein we were deleting all entries from list; fix this by removing list_for_each_entry_safe() call. Signed-off-by:

A full-channel scan is split to multiple scan commands in driver before they are sent to firmware. When each scan result is back the SSID entries are parsed and informed to cfg80211 directly. It's observed that sometimes userspace may initiate association as soon as the target AP is found. During the 4-way handshake firmware may go off-channel to scan the remaining channels. This causes the 4-way handshake to fail. Fix it by checking 'scan_block' flag and aborting the remaining scan in this case. 'scan_block' flag is set after association and before 4-way handshake. It gets cleared after 4-way handshake is completed. Tested-by:

As the variable is used only for preparation of internal scan commands, we don't need to keep it allocated until the entire scan completes. We will define it as a local variable and free immediately after it's use. New flag 'scan_aborting' is added to handle race between mwifiex_close() and scan handler. Previously user_scan_cfg pointer used to take care of this. This patch fixes a memory leak in mwifiex_cfg80211_scan after running "iwlist mlan0 scan & sleep 1; rmmod mwifiex_sdio". Reported-by:

Return from scan delay timer routine if surprise_removed flag is true. Also, cancel the timer in unload path. This fixes a crash when scan delay timer accesses structures that have been freed already. Tested with "iwlist mlan0 scan & sleep 1; rmmod mwifiex_sdio" Reported-by:

We have two different static routines with name mwifiex_free_adapter(). The routine in main.c actually frees the adapter structure. We will rename other routine in init.c to mwifiex_adapter_cleanup() to avoid confusion. Signed-off-by:

- Introduce common code for Tx/Rx descriptor physical address set/parse - Fix endianness for address fields - consistent descriptor naming: '_d' for non-cached memory, 'd' for cached copy - wil_tx_desc_map now modify cached copy, no need for 'volatile' Signed-off-by:

Introduce NAPI for Rx and Tx completion. This fixes packet reordering that happens when Rx handled right in the IRQ: netif_rx puts packet in 'percpu' queue, then network stack fetches packets from 'percpu' queues for processing, with different pattern of queue switching. As result, network stack see packets in different order. This causes hard to understand TCP throughput degradation in about 30min Complete polling if only one packet was processed - this eliminates empty polls that would be otherwise done at the end of each burst Signed-off-by:

Chun-Yeow and Javier Lopez contributed these changes to make mesh mode use the more similar AP beaconing mode and queue parameters. Should improve PS performance, interface concurrency (AP modes can coexist), and beacon interval stability. AR9271 (ath9k_htc) mesh interfaces also need to be in AP operating mode. Signed-off-by:

The beacon data queue is initialized already when the rt2800_clear_beacon_register() function is called. Fetch the size of the TXWI descriptor from that instead of using the winfo_size field of the data queue descriptor. The two values are the same, and the use of the rt2x00dev->bcn->winfo_size value allows us to get rid of a superfluous pointer dereference. Signed-off-by:
