At least in the i.MX series, the flexcan contrller divides into ver_3
and ver_10, current driver is for ver_3 controller.

i.MX6 has ver_10 controller, it has more reigsters than ver_3 has.
The rxfgmask (Rx FIFO Global Mask) register is one of the new added.
Its reset value is 0xffffffff, this means ID Filter Table must be
checked when receive a packet, but the driver is designed to accept
everything during the chip start, we need to clear this register to
follow this design.

Use the data entry of the struct of_device_id to point chip specific
info, we can set hardware version for each platform.

The "bat_" prefix in the source files implementing the batman-adv sysfs and
debugfs interface doesn't have a special meaning and are only used by these
files and files that implement the actual B.A.T.M.A.N. path finding algorithm.

The prefix is better suited to mark files that are used to implement the main
part of the path finding. All other files should not use it and therefore gets
renamed.

This patch adds the support for the Energy-Efficient Ethernet (EEE)
to the Physical Abstraction Layer.
To support the EEE we have to access to the MMD registers 3.20 and
7.60/61. So two new functions have been added to read/write the MMD
registers (clause 45).

An Ethernet driver (I tested the stmmac) can invoke the phy_init_eee to properly
check if the EEE is supported by the PHYs and it can also set the clock
stop enable bit in the 3.0 register.
The phy_get_eee_err can be used for reporting the number of time where
the PHY failed to complete its normal wake sequence.

In the end, this patch also adds the EEE ethtool support implementing:
 o phy_ethtool_set_eee
 o phy_ethtool_get_eee

v1: initial patch
v2: fixed some errors especially on naming convention
v3: renamed again the mmd read/write functions thank to Ben's feedback
v4: moved file to phy.c and added the ethtool support.
v5: fixed phy_adv_to_eee, phy_eee_to_supported, phy_eee_to_adv return
    values according to ethtool API (thanks to Ben's feedback).
    Renamed some macros to avoid too long names.
v6: fixed kernel-doc comments to be properly parsed.
    Fixed the phy_init_eee function: we need to check which link mode
    was autonegotiated and then the corresponding bits in 7.60 and 7.61
    registers.
v7: reviewed the way to get the negotiated settings.
v8: fixed a problem in the phy_init_eee return value erroneously added
    when included the phy_read_status call.
v9: do not remove the MDIO_AN_EEE_ADV_100TX and MDIO_AN_EEE_ADV_1000T
    and fixed the eee_{cap,lp,adv} declaration as "int" instead of u16.

This patch adds the Energy Efficient Ethernet support to the stmmac.

Please see the driver's documentation for further details about this support
in the driver.

Thanks also goes to Rayagond Kokatanur for his first implementation.

Note:
 to clearly manage and expose the lpi interrupt status and eee ethtool
 stats I've had to do some modifications to the driver's design and I
 found really useful to move other parts of the code (e.g. mmc irq stat)
 in the main directly. So this means that some core has been reworked
 to introduce the EEE.

v1: initial patch
v2: fixed some sparse issues (typos)
v3: erroneously sent the v2 renamed as v3
v4:
	o Fixed the return value of the stmmac_eee_init as suggested by D.Miller
	o Totally reviewed the ethtool support for EEE
	o Added a new internal parameter to tune the SW timer for TX LPI.
v5: do not change any eee setting in case of the stmmac_ethtool_op_set_eee fails
    (it has to return -EOPNOTSUPP in that case).

This patch adds a hook in the binding path of netlink.

This is used by ctnetlink to allow module autoloading for the case
in which one user executes:

 conntrack -E

So far, this resulted in nfnetlink loaded, but not
nf_conntrack_netlink.

I have received in the past many complains on this behaviour.

This patch adds the following structure:

struct netlink_kernel_cfg {
        unsigned int    groups;
        void            (*input)(struct sk_buff *skb);
        struct mutex    *cb_mutex;
};

That can be passed to netlink_kernel_create to set optional configurations
for netlink kernel sockets.

I've populated this structure by looking for NULL and zero parameters at the
existing code. The remaining parameters that always need to be set are still
left in the original interface.

That includes optional parameters for the netlink socket creation. This allows
easy extensibility of this interface in the future.

This patch also adapts all callers to use this new interface.

Here is another batch of updates intended for 3.6.  This includes a
number of pulls, including ones from the mac80211, iwlwifi, ath6kl, and
wl12xx trees.  I also pulled from the wireless tree to avoid potential
build conflicts.  There are a number of other patches applied directly,
including a number for the Broadcom drivers and the mwifiex driver.

The updates cover the usual variety of new hardware support and feature
enhancements.  It's all good work, but there aren't any big headliners.
This does resolve a net-next/wireless-next merge conflict reported

If rpfilter is off (or the SKB has an IPSEC path) and there are not
tclassid users, we don't have to do anything at all when
fib_validate_source() is invoked besides setting the itag to zero.

We monitor tclassid uses with a counter (modified only under RTNL and
marked __read_mostly) and we protect the fib_validate_source() real
work with a test against this counter and whether rpfilter is to be
done.

Having a way to know whether we need no tclassid processing or not
also opens the door for future optimized rpfilter algorithms that do
not perform full FIB lookups.
