Micrel KSZ8081 and KSZ8091 PHYs have the RMII Reference Clock Select
bit, which is used to select 25 or 50 MHz clock mode.
Note that on some revisions of the PHY (e.g. KSZ8081RND) the function of
this bit is inverted so that setting it enables 25 rather than 50 MHz
mode. Add a new device-tree property
"micrel,rmii-reference-clock-select-25-mhz" to describe this.

Add generic RMII-Reference-Clock-Select support.
Several Micrel PHY have an RMII-Reference-Clock-Select bit to select
25 MHz or 50 MHz clock mode. Recently, support for configuring this
through device tree for KSZ8021 and KSZ8031 was added.
Generalise this support so that it can be configured for other PHY types
as well.
Note that some PHY revisions (of the same type) has this bit inverted.
This should be either configurable through a new device-tree property,
or preferably, determined based on PHY ID if possible.
Also note that this removes support for setting 25 MHz mode from board
files which was also added by the above mentioned commit 45f56cb82e45
("net/phy: micrel: Add clock support for KSZ8021/KSZ8031").

Add has_broadcast_disable flag to type-data and generic config_init.
This allows us to remove the ksz8081 config_init callback.

Commit ae5c6c6d "ptp: Classify ptp over ip over vlan packets" changed the
code in two drivers that matches time stamps with PTP frames, with the goal
of allowing VLAN tagged PTP packets to receive hardware time stamps.
However, that commit failed to account for the VLAN header when parsing
IPv4 packets. This patch fixes those two drivers to correctly match VLAN
tagged IPv4/UDP PTP messages with their time stamps.
This patch should also be applied to v3.17.

When advertised capabilities are changed with mii-tool, such as:
mii-tool -A 10baseT
the existing handler has two errors.
- An actual PHY register value is provided by mii-tool, and this
must be mapped to internal state with mii_adv_to_ethtool_adv_t().
- The PHY state machine needs to be told that autonegotiation has
again been performed. If not, the MAC will not be notified of
the new link speed and duplex, resulting in a possible config
mismatch.

bcm7445_config_init() was working around non-production version of the
PHY HW block, so just remove it entirely.
bcm7xxx_28nm_afe_config_init() was running for all PHY revisions greater

revision, so rename the function accordingly and update the GPHY macro
to use the generic config_init callback.

When a sysfs binary file is asked to be removed, it is found by
attribute name, so strictly speaking this change is not a fix, but
just in case when attribute name is changed in the driver or sysfs
internals are changed, it might be better to remove the previously
created file using right the same binary attribute.

Bug: Unable to send and receive Ethernet packets with Micrel PHY.
Affected devices:
KSZ8031RNL (commercial temp)
KSZ8031RNLI (industrial temp)
Description:
PHY device is correctly detected during probe.
PHY power-up default is 25MHz crystal clock input
and output 50MHz RMII clock to MAC.
Reconfiguration of PHY to input 50MHz RMII clock from MAC
causes PHY to become unresponsive if clock source is changed
after Operation Mode Strap Override (OMSO) register setup.
Cause:
Long lead times on parts where clock setup match circuit design
forces the usage of similar parts with wrong default setup.
Solution:
Swapped KSZ8031 register setup and added phy_write return code validation.
Tested with Freescale i.MX28 Fast Ethernet Controler (fec).

The mdio-sun4i driver automatically selects REGULATOR and
REGULATOR_FIXED_VOLTAGE because it uses the regulator API. But a
driver selecting a subsystem increases the chance of generating
circular Kconfig dependencies, especially when other drivers depend on
the selected symbol.
Since the regulator API functions are replaced with no-ops when
REGULATOR is disabled, the driver can be built successfully even
without regulator support and so those 'select' dependencies can be
safely dropped.

The phy timestamping takes a different path than the regular timestamping
does in that it will create a clone first so that the packets needing to be
timestamped can be placed in a queue, or the context block could be used.
In order to support these use cases I am pulling the core of the code out
so it can be used in other drivers beyond just phy devices.
In addition I have added a destructor named sock_efree which is meant to
provide a simple way for dropping the reference to skb exceptions that
aren't part of either the receive or send windows for the socket, and I
have removed some duplication in spots where this destructor could be used
in place of sock_edemux.

Since device resets can change the current mode it's possible to think
the device is in a different mode than it actually is. Rather than
trying to determine every place that is needed to set/save the current
mode, be safe and check the devices actual mode when needed rather than
trying to track it.
