sfc: SFN8000 support improvements

This series improves support for the recently released SFN8000 series
of adapters. Specifically, it retrieves interrupt moderation timer
settings directly from the adapter and uses those settings. It also
uses a new event queue initialisation interface, allowing specification
of a performance objective rather than enabling individual flags.
====================

On SFN8000 series adapters the MC provides a method to get the timer
quantum and the maximum timer setting. We revert to the old values if the
new call is unavailable.

SFN8000-series NICs require a new method of setting interrupt moderation,
via MCDI. This is indicated by a workaround flag. This new MCDI command
takes an explicit time value rather than a number of ticks. It therefore
makes sense to also store the moderation values in terms of time, since
that is what the ethtool interface is interested in.

Rather than explicitly specifying flags we can now specify a desired

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.

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.

- removed patch:
  net: ethernet: ti: cpsw: fix int dbg message
- replaced patch:

  on "net: ethernet: ti: cpsw: remove intr dbg msg from poll handlers"
- removed macro "cpsw_get_slave_ndev"
- corrected some commits

- added several patch improvements
- avoided variable reordering in structures
- removed static variable for common function

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 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.
