2013-07-26mwifiex: handle driver initialization error pathsAmitkumar Karwar2-28/+56
mwifiex_fw_dpc() asynchronously takes care of firmware download and initialization. Currently the error paths in mwifiex_fw_dpc() are not handled. So if wrong firmware is downloaded, required cleanup work is not performed. memory is leaked and workqueue remains unterminated in this case. mwifiex_terminate_workqueue() is moved to avoid forward declaration.

2013-07-24mwifiex: correction in mwifiex_check_fw_status() return statusAmitkumar Karwar1-2/+0
For PCIe cards, when wrong firmware is downloaded, firmware is failed to be ready in 10 seconds. We should return an error at this point. But currently we are sending first command to firmware. As expected firmware doesn't respond to this command and command timeout occurs. This patch fixes the problem by removing unnecessary 'ret' variable modifications in "if (ret) {" block. The block is just supposed to update "adapter->winner" flag. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

2013-07-24mwifiex: replace mdelay with msleepAmitkumar Karwar2-2/+2
It is observed that when wrong firmware is downloaded for PCIe card, system hangs for 10 seconds. The reason is mdelay() is used when firmware status is polled.

2013-07-24mwifiex: reduce firmware poll retriesAmitkumar Karwar2-4/+0
After downloading the firmware, firmware status is checked by reading a register. Polling interval is 100 msecs. Therefore 100 retries means the status is checked for 10 secs which is more than sufficient for firmware to get ready. This patch removes 1000 retries macro usage, because 100secs time is not practical.

2013-07-24mwifiex: add unregister_dev handler for usb interfaceAmitkumar Karwar1-0/+8
Clear the data pointer stored in USB interface structure in this handler. This helps to return from mwifiex_usb_disconnect() if driver deinitialization is already performed while handling an error path for mwifiex_usb_probe(). USB8797 card gets enumerated twice. First enumeration is for firmware download and second enumeration expects firmware initialization. mwifiex_usb_probe() always takes care of deinitialization for first enumeration after firmware download. Also, this change matches our handling for SDIO and PCIe interfaces. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

2013-07-22mwifiex: fix IRQ enable/disableDaniel Drake5-61/+57
During tear down (e.g. mwifiex_sdio_remove during system suspend), mwifiex left IRQs enabled for a significant period of time when it was unable to handle them correctly. This caused interrupt storms and interfered with the bluetooth interface on the same SDIO card. Solve this by disabling interrupts at the point when they can no longer be handled correctly, which is at the start of mwifiex_remove_card(). For cleanliness, we now enable interrupts in the mwifiex_add_card() path, to be symmetrical with the disabling of interrupts. We also couple the registration of the sdio IRQ handler with the actual enable/disable of interrupts at the hardware level. I also removed a write to this register in mwifiex_init_sdio which seemed pointless and won't cause any ill effects now that we only register the SDIO IRQ handler when we are ready to accept interrupts.

2013-06-17mwifiex: fix memory corruption when unsetting multicast listDaniel Drake2-13/+10
When trying to unset a previously-set multicast list (i.e. the new list has 0 entries), mwifiex_set_multicast_list() was calling down to mwifiex_request_set_multicast_list() while leaving mcast_list.num_multicast_addr as an uninitialized value. We were arriving at mwifiex_cmd_mac_multicast_adr() which would then proceed to do an often huge memcpy of mcast_list.num_multicast_addr*ETH_ALEN bytes, causing memory corruption and hard to debug crashes. Fix this by setting mcast_list.num_multicast_addr to 0 when no multicast list is provided. Similarly, fix up the logic in mwifiex_request_set_multicast_list() to unset the multicast list that was previously sent to the hardware in such cases.

2013-05-22mwifiex: add support for Marvell SD8897 chipsetYogesh Ashok Powar3-61/+315
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.

2013-05-22mwifiex: code rearrangement in multiport aggregation pathAmitkumar Karwar2-36/+64
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: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

2013-05-22mwifiex: replace spin_lock_irqsave with spin_lock and fix warn_onAvinash Patil1-3/+2
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.

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.
