The result of container_of should not be NULL. In particular, in this case
the argument to the enclosing function has passed though INIT_WORK, which
dereferences it, implying that its container cannot be NULL.
A simplified version of the semantic patch that makes this change is as
follows:

This patch roughly implements xmit aggregation for ar9170-like device.
Not all AP are compatible with the driver(and firmware) yet, so YMMV.
A more refined code will definitely need the final HT specification
to be available for the public, lots of firmware modification and
possibly a redesigned driver just for good measure.
Sadly, these conditions won't come true anytime soon...

Implement set_tim callback for all rt2x00 drivers, this makes the
device wake up powersaving stations properly while in AP mode.
The only way to update the beacon is by simply calling mac80211 and
requesting the new beacon. This means the set_tim() event is mostly the
same as a beacon_done() event which was already defined in rt2x00lib.

We need to provide a reasonable minimum that will result in a
working setup if used. Set minimum to be 10 to provide for
4 standard TX queues + 1 command queue + 2 (unused) HCCA queues +
4 HT queues (one per AC).
We allow the user to change the number of queues used via a module
parameter and use this minimum value to check if it is valid. Without
this patch a user can select a value for the number of queues that
will result in a failing setup.

Certain types of control packets (LLDP, LACP, etc.) are not supposed to have a
priority tag or vlan tag inserted. Ixgbe driver is currently priority
tagging everything (if packet is not on a VLAN interface).
This patch modifies DCB mode, so that packets marked with skb priority
TC_PRIO_CONTROL are not priority tagged. It also transmits these packets on
the highest priority traffic class.
Programs (like dcbd) can set the skb priority using a socket option. Or, a tc
filter can be configured to set the priority value. Using the value
TC_PRIO_CONTROL (7) has the benefit that it is already defined in the kernel,
and the bonding LACP code already sets the skb->priority field to this value.

at91ether_probe lives in .init.text, so using platform_driver_register
to register it is wrong because binding a device after the init memory
is discarded (e.g. via sysfs) results in an oops.
As requested by David Brownell platform_driver_probe is used instead of
moving the probe function to .devinit.text as proposed initially.
This saves some memory, but devices registered after the driver is
probed are not bound (probably there are none) and binding via sysfs
isn't possible.

Fixed-link support is broken for the ucc_eth, gianfar, and fs_enet
device drivers. The "OF MDIO rework" patches removed most of the
support. Instead of re-adding fixed-link stuff to the drivers, this
patch adds a support function for parsing the fixed-link property
and obtaining a dummy phy to match.
Note: the dummy phy handling in arch/powerpc is a bit of a hack and
needs to be reworked. This function is being added now to solve the
regression in the Ethernet drivers, but it should be considered a
temporary measure until the fixed link handling can be reworked.

Adding support for BCM8727 - a dual port SFP+ PHY. That includes verification of
the optic module vendor and part number - the list of approved modules resides
on the nvram and the module is verified by the FW. Since not all users would
like to use this verification feature, it can be disabled. The default behavior
is to issue a warning if the module is not approved, but still allow using it -
but it is also possible to disable the link if the module is not approved.

For AP mode we must tune ANI specially for 2 GHz and
for 5 GHz. We mask in only the flags we want to toggle
on ath9k_hw_ani_control() through the ah->ani_function
bitmask, this will take care of ignoring changes during
ANI reset which we were disabling before.

This changes the power_level file to adhere to the "one value

requested as it will be the number just written to this file. It
is thus not necessary to create a new sysfs file for this value.
In addition it fixes a problem where powertop's parsing expects
this value to be the first value in this file without any descriptions.

netxen: fix deadlock on dev close
The tx ring accounting fix in commit cb2107be43
("netxen: fix tx ring accounting") introduced intermittent
deadlock when inteface is going down.
This was possibly combined effect of speculative tx pause,
calling netif_tx_lock instead of queue lock and unclean
synchronization with napi which could end up unmasking

The connector documentation states that the argument to the callback
function is always a pointer to a struct cn_msg, but rather than encode it
in the API itself, it uses a void pointer everywhere. This doesn't make
much sense to encode the pointer in documentation as it prevents proper C
type checking from occurring and can easily allow people to use the wrong
pointer type. So convert the argument type to an explicit struct cn_msg
pointer.

Bonding device forbids slave device of different types under the same
master.
However, it is possible for a bonding master to change type during its
lifetime. This can be either from ARPHRD_ETHER to ARPHRD_INFINIBAND
or the other way arround. The change of type requires device level
multicast address cleanup because device level multicast addresses
depend on the device type.
The patch adds a call to dev_close() before the bonding master changes
type and dev_open() just after that.
In the example below I enslaved an IPoIB device (ib0) under
bond0. Since each bonding master starts as device of type ARPHRD_ETHER
by default, a change of type occurs when ib0 is enslaved.
This is how /proc/net/dev_mcast looks like without the patch

5 bond0 1 0 01005e000116

6 ib0 1 0 00ffffffff12601bffff00000000000000000001
and this is how it looks like after the patch.
