Amitkumar Karwar 98a4635bba mwifiex: fix potential mem leak in .del_virtual_intf
1) Currently we freeing wdev for each interface in driver unload
path. We may leak memory if user have already deleted an interface.
mwifiex_add_virtual_intf() allocates wdev structure. So it should
be freed in mwifiex_del_virtual_intf().
This will make sure that wdev will be freed when user deletes an
interface and also in unload path.
2) "priv->netdev->ieee80211_ptr" should also be cleared in
mwifiex_del_virtual_intf.

Amitkumar Karwar bec568ff51 mwifiex: failure path handling in mwifiex_add_virtual_intf()
1) If register_netdevice() is failed, we are freeing netdev
pointer, but priv->netdev is not cleared. This gives kernel
paging request error when driver is unloaded or interface is
deleted. Fix the problem by clearing the pointer.
2) Fix memory leak issue by freeing 'wdev' in failure paths.
Also, clear priv->wdev pointer.

As mwifiex_add_virtual_intf() successfully handles the
failure conditions, redundant code under err_add_intf label
is removed in this patch.

Amitkumar Karwar 562fc5b30f mwifiex: add packet coalesce support
Coalesce filters are configured in firmware based on settings
received from cfg80211.

Packet type which is required by firmware is determined based on
provided patterns in a rule:

Unicast: if pattern '01' with offset 0 is found
Multicast: if pattern '33:33' or '01:00:5e' with offset 0 is found
Broadcast: if pattern 'ff:ff:ff:ff' with offset 0 is found

Some example coalesce configuration files:

1) Coalesce Rx data packets from 192.168.0.88
mac address of our device is 00:50:43:21:53:7A
Source IP address offset comes out as 52 after following
calculations:
    32 bytes of HW 802.11 header + 8 bytes LLC +
    12 bytes in IPV4 header till source IP address
Destination mac is at offset 6 in HW header.

delay=100
condition=1
patterns=01,6+00:50:43:22,10+53:7A,52+c0:a8:00:58

2) Coalesce all broadcast and multicast packets(Multiple packet
types are not allowed in a single rule. Hence created separate
rules)

delay=400
condition=1
patterns=33:33
delay=400
condition=1
patterns=ff:ff:ff:ff

Avinash Patil 953b3539ef mwifiex: check for bss_role instead of bss_mode for STA operations
This patch fixes an issue wherein association would fail on P2P
interfaces. This happened because we are checking priv->mode
against NL80211_IFTYPE_STATION. While this check is correct for
infrastructure stations, it would fail P2P clients for which mode
is NL80211_IFTYPE_P2P_CLIENT.

Better check would be bss_role which has only 2 values: STA/AP.

Amitkumar Karwar 75ab753d77 mwifiex: remove global user_scan_cfg variable
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".

Conflicts:
	Documentation/networking/ip-sysctl.txt
	drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c

Both conflicts were simply overlapping context.

A build fix for qlcnic is in here too, simply removing the added
devinit annotations which no longer exist.

Luis R. Rodriguez 0c0280bd0b wireless: make the reg_notifier() void
The reg_notifier()'s return value need not be checked
as it is only supposed to do post regulatory work and
that should never fail. Any behaviour to regulatory
that needs to be considered before cfg80211 does work
to a driver should be specified by using the already
existing flags, the reg_notifier() just does post
processing should it find it needs to.

Also make lbs_reg_notifier static.

Amitkumar Karwar d7b9c5204e mwifiex: update config_bands during infra association
Currently "adapter->config_bands" is updated during infra
association only if channel is provided by user in "iw connect"
command. config_bands is used while preparing association
request to calculate supported rates by intersecting our rates
with the rates advertised by AP.

There is corner case in which we include zero rates in
supported rates TLV based on previous IBSS network history,
which leads to association failure.

This patch fixes the problem by correctly updating config_bands.
