Rather than explicitly specifying flags we can now specify a desired
performance target to the firmware, ie higher throughput or lower latency.
For now we use the default "auto" configuration.

====================
net: phy: Add xilinx gmiitorgmii converter support
The Gigabit Media Independent Interface (GMII) to Reduced Gigabit Media
Independent Interface (RGMII) core provides the RGMII between RGMII-compliant
Ethernet physical media devices (PHY) and the Gigabit Ethernet controller.
This core can be used in all three modes of operation(10/100/1000 Mb/s).
The Management Data Input/Output (MDIO) interface is used to configure the
Speed of operation. This core can switch dynamically between the three
Different speed modes by configuring the conveter register through mdio write.
The conveter sits b/w the MAC and external phy like below
MACB <==> GMII2RGMII <==> RGMII_PHY
MDIO <========> GMII2RGMII
MCAB <=======>
<========> RGMII
Using MAC MDIO bus we can access both the converter and the external PHY.
We need to program the line speed of the converter during run time based
On the external phy negotiated speed.
This patch series does the below
---> Add mask for Control register 10Mbps speed.
---> Add support for xilinx gmiitorgmii converter.

Depending on which method the driver implements, userspace could
call this (indirectly, by getting station info) before the driver
knows about the station, possibly causing it to misbehave.
Therefore, add a check for sta->uploaded which indicates that the
driver knows about the station.

This change alters the semantics of NL80211_CMD_DEL_INTERFACE events
by always sending this event whenever a net_device object associated
with a wdev is destroyed. Prior to this change, this event was only
emitted as a result of NL80211_CMD_DEL_INTERFACE command sent from
userspace. This allows userspace to reliably detect when wireless
interfaces have been removed, e.g. due to USB removal events, etc.
For wireless device objects without an associated net_device (e.g.
NL80211_IFTYPE_P2P_DEVICE), the NL80211_CMD_DEL_INTERFACE event is
now generated inside cfg80211_unregister_wdev.

This change alters the semantics of NL80211_CMD_NEW_INTERFACE events
by always sending this event whenever a new net_device object

was only sent as a result of NL80211_CMD_NEW_INTERFACE command sent
from userspace. This allows userspace to reliably detect new wireless
interfaces (e.g. due to hardware hot-plug events, etc).
For wdevs created without an associated net_device object (e.g.
NL80211_IFTYPE_P2P_DEVICE), the NL80211_CMD_NEW_INTERFACE event is
still generated inside the relevant nl80211 command handler.

net: ethernet: ti: cpsw: split driver data and per ndev data
In dual_emac mode the driver can handle 2 network devices. Each of them can use
its own private data and common data/resources. This patchset splits common driver
data/resources and private per net device data.
It leads to:
- reduce memory usage
- increase code readability
- allows add a bunch of simplification
- create prerequisites to add multi-channel support,
when channels are shared between net devices
Doesn't have bad impact on performance.
v2: https://lkml.org/lkml/2016/8/6/108
Since v2:
- removed patch:
net: ethernet: ti: cpsw: fix int dbg message
- replaced patch:
"net: ethernet: ti: cpsw: remove redundant check in napi poll"
on "net: ethernet: ti: cpsw: remove intr dbg msg from poll handlers"
- removed macro "cpsw_get_slave_ndev"
- corrected some commits
Since v1:
- added several patch improvements
- avoided variable reordering in structures
- removed static variable for common function
- split big patch on several patches:

The PPTP is encapsulated by GRE header with that GRE_VERSION bits
must contain one. But current GRE RPS needs the GRE_VERSION must be
zero. So RPS does not work for PPTP traffic.
In my test environment, there are four MIPS cores, and all traffic
are passed through by PPTP. As a result, only one core is 100% busy
while other three cores are very idle. After this patch, the usage
of four cores are balanced well.

Convert the per-device linked list into a hashtable. The primary
motivation for this change is that currently, we're not tracking all the
qdiscs in hierarchy (e.g. excluding default qdiscs), as the lookup
performed over the linked list by qdisc_match_from_root() is rather
expensive.
The ultimate goal is to get rid of hidden qdiscs completely, which will
bring much more determinism in user experience.

the active device's ic_device is still used however to print the
ipconfig summary which results in an oops if the memory is already
changed. So delay freeing until after the autoconfig results are
reported.

The interface would not function after the system had been woken up
after have been suspended (echo mem > /sys/power/state) cycle. The
reason for this is that all device registers have been reset to its
default values. This patch adds sleep suspend and resume functions that
detached the interface at suspend and restore the registers and reattach
the interface at resume.
Only the registers that are only configured at probe time needs to be
explicitly restored by the resume handler. All other registers are
reconfigured by either reopening the device in the resume handler (if
the device was running when the system was suspended) or when the
interface is opened by a user at a later time.

Userspace programs generally need to know the name of the ppp devices
they create. Both ioctl and rtnl interfaces use the ppp<suffix> sheme
to name them. But although the suffix used by the ioctl interface can
be known by userspace (it's the PPP unit identifier returned by the
PPPIOCGUNIT ioctl), the one used by the rtnl is only known by the
kernel.
This patch brings more consistency between ioctl and rtnl based ppp
devices by generating device names using the PPP unit identifer as
suffix in both cases. This way, userspace can always infer the name of
the devices they create.
