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 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

After SKB is queued into tx_queue, it will be freed if request_gop is NULL.
However, no dequeue action is called in this situation, it is likely that
tx_queue constains freed SKB. This patch should fix this issue, and it is
based on 3.5.0-rc4+.
This issue is found through code inspection, no bug is seen with it currently.
I run netperf test for several hours, and no network regression was found.

The correct behavior is to program the interrupt coalescing regs
(RXICr/TXICr) in accordance with the Rx/Tx Q's "rx/txcoalescing"
flag. That is, if the coalescing flag is 0 for a given Rx/Tx queue
then the corresponding coalescing register should be cleared.
This behavior is correctly implemented for the single-queue mode
(SQ_SG_MODE), but not for the multi-queue mode (MQ_MG_MODE).
This fixes the later case.

In commit 7a87982420 we added
a wrapper for the WDIOC_GETSTATUS ioctl call. The code results
however in a different behaviour: it returns an error if the
driver doesn't support the status operation. This is not
according to the API that says that when we don't support
the status operation, that we just should return a 0 value.
Only when the device isn't there anymore, we should return an

We miss to wakeup main thread after adding command to cmd pending
queue at follwing places. These commands are handled later when
main thread is woken up for handling an interrupt for sleep event
from firmware. This adds worst case delay of 50msec.
1) We don't wakeup main thread when asynchronous command is added
to cmd pending queue. Move queue_work() call from
mwifiex_wait_queue_complete() to mwifiex_send_cmd_async() to wakeup
main thread for sync as well as async commands.
2) Scan operation is triggered due to following reasons
a) request from user (ex. "iw scan" command)
b) Scan performed by driver internally.
In first case main thread is woken up when first scan command is
queued in cmd pending queue (we don't need to wakeup main thread for
subsequent scan commands, because they are queued in scan command
response handler), but it is not done for second case. queue_work()
is moved inside mwifiex_scan_networks() to handle both the cases.
