Low level driver could pass rx frames to us after disassociate, what
can lead to run conn_mon_timer by ieee80211_sta_rx_notify(). That
is obviously wrong, but nothing happens until we unload modules and
resources are used after free. If kernel debugging is enabled following
warning could be observed:

The DMA latency issue is observed only in Intel pinetrail platforms
but in the driver we had a default PM-QOS value of 55. This caused
unnecessary power consumption and battery drain in other platforms.
Remove the pm-qos thing in the driver code and address the throughput
issue in Intel pinetrail platfroms in user space using any one of
the scripts in below links:
http://www.kernel.org/pub/linux/kernel/people/mcgrof/scripts/cpudmalatency.c
http://johannes.sipsolutions.net/files/netlatency.c.txt

The module parameter ieee80211_disable_40mhz_24ghz
was meant to allow disabling 40 MHz operation in
the 2.4 GHz band by default. However, it is buggy
as implemented because while it advertises to the
AP that the device doesn't support 40 MHz, it will
itself still use 40 MHz configurations.
To fix this, clear the 40 MHz bits from the sband
completely instead of overriding where used.

ssb_wait_bit was designed for only one-bit bitmasks.
People start using it for multi-bit bitmasks. Make the "set" case
is safe for this. The "unset" case is already safe.
This does not change behavior of the current code.

l2cap_load() was added to trigger l2cap.ko module loading from the RFCOMM
and BNEP modules. Now that L2CAP module is gone, we don't need it anymore.

Actually doesn't make sense have these modules built separately.
The L2CAP layer is needed by almost all Bluetooth protocols and profiles.
There isn't any real use case without having L2CAP loaded.
SCO is only essential for Audio transfers, but it is so small that we can
have it loaded always in bluetooth.ko without problems.
If you really doesn't want it you can disable SCO in the kernel config.

struct sco_conninfo has one padding byte in the end. Local variable
cinfo of type sco_conninfo is copied to userspace with this uninizialized
one byte, leading to old stack contents leak.
