This series includes error case handling, bridged packet handling
in AP mode, p2p updates, random cleanups, etc.
Amitkumar Karwar (11):
mwifiex: add PCIe shutdown handler to avoid system hang on reboot
mwifiex: move del_timer_sync(scan_delay_timer) call to fix memleak
mwifiex: remove unnecessary del_timer(cmd_timer)
mwifiex: move if_ops.cleanup_if() call
mwifiex: add unregister_dev handler for usb interface
mwifiex: reduce firmware poll retries
mwifiex: replace mdelay with msleep
mwifiex: correction in mwifiex_check_fw_status() return status
mwifiex: handle driver initialization error paths
mwifiex: code rearrangement in sdio.c
mwifiex: remove duplicate structure host_cmd_tlv
Avinash Patil (5):
mwifiex: rename pkt_count to ba_pkt_count in mwifiex_ra_list_tbl
struct
mwifiex: maintain outstanding packet count for RA list instead of
packet size
mwifiex: delete AP TX queues when bridged packets reach threshold
mwifiex: correct max IE length check for WPS IE
mwifiex: modify mwifiex_ap_sta_limits to advertise support for P2P
Huawei Yang (2):
mwifiex: remove stop_net_dev_queue operation in AP forwarding
mwifiex: add tx info to skb when forming mgmt frame
Stone Piao (3):
mwifiex: discard deauth and disassoc event during WPS session

From: Huawei Yang <harvey.huawei.yang@gmail.com>
Under uAP mode mwifiex may stop all net tx queues on forwarding
packets. This may stop some tx queues and they never have chance
to be waked up. There is also no need to check tx_pending and
stop queues here. Because local host has such kind of check when
transmitting packets and it's not proper to have forwarding affect
local transmitting.

pkt_count is used to determine if BA can be formed on this RA list
by comparing it with randomly generated BA threshold. The pkt_count
variable name here is ambiguous and does not reflect its usage
correctly. Rename it to ba_pkt_count.

Maintain total outstanding packet count for RA list instead of total
outstanding size as packet count metric seems more reasonable for
checking threshold etc.

Delete packets from TX queues for this mwifiex_private structure
when bridged packet count reaches maximum threshold. Bridged packets
from each RA List are deleted till they fall to low threshold of 128.

In function 'mwifiex_write_data_complete' it need tx info to find
the mwifiex_private to updates statistics and wake up tx queues.
Or we may trigger tx queues timeout when transmitting lots of mgmt
frames.

Some GO will send deauth or disassoc packet at the end of WPS
handshake, which causes P2P connecion failure due to the race
condition between event path and data path.

Before sending command to firmware, we need to check the frame type.
We skip registering the mgmt frame that has already been registered.

During P2P handshake, P2P client needs to send deauth after EAPOL
FAILURE to GO. We need add bss mode for P2P client when handle deauth
request.
Without this change, deauth can not be sent out from P2P client side.

Currently it is in mwifiex_adapter_cleanup() which doesn't get
called if driver initialization is failed causing memory leak.
scan_delay_timer is initialized in mwifiex_register(), so it
should be deleted in mwifiex_unregister(). Hence it has been
moved to appropriate place.

corresponding cleanup routine should be called in

Currently it's there in mwifiex_adapter_cleanup(), hence
interface specific cleanup is not performed if driver

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.

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.

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.
Replace mdelay with msleep(non-blocking API) to fix the issue.

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.

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.

We support maximum simultaneous 2 non-AP station interfaces and
they can assume role of Station/P2P client/P2P GO.
Advertise this support to cfg80211 so that concurrent P2P/STA
operation is possible.

This one didn't apply on the current wireless-next tree. Can you

Hi John,
> This one didn't apply on the current wireless-next tree. Can you
> fix it up?
18/21 and 19/21 depend on this patch:
commit 232fde062e0a2cc52e8e18a50cda361b4ba88f34
Author: Daniel Drake <dsd@laptop.org>
Date: Sat Jul 13 10:57:10 2013 -0400
mwifiex: fix IRQ enable/disable
which is in wireless.git and wireless-testing.git currently.
We can apply 18 and 19 later after commit 232fde0 is merged back to wireless-next.git.
(I will send you a reminder to merge these two patches once commit 232fde0 is in -next tree.)
Thanks,
Bing
