Normally, if a reset fails due to failover or other communication error
there is another reset (eg: FAILOVER) in the queue and we would process
that reset. But if we are unable to communicate with PHYP or VIOS after
H_FREE_CRQ, there would be no other resets in the queue and the adapter
would be in an undefined state even though it was in the OPEN state
earlier. While starting the reset we set the carrier to off state so
we won't even get the timeout resets.

If the last queued reset fails, retry it as a hard reset (after the
usual 60 second settling time).

Setting the EXT_ENERGY_DET_MASK bit allows the port energy detection
logic of the internal PHY to prevent the system from sleeping. Some
internal PHYs will report that energy is detected when the network
interface is closed which can prevent the system from going to sleep
if WoL is enabled when the interface is brought down.

Since the driver does not support waking the system on this logic,
this commit clears the bit whenever the internal PHY is powered up
and the other logic for manipulating the bit is removed since it
serves no useful function.

Introducing a new mailbox to support updating lmt entries

Parameters passed to mailbox includes the primary pcifunc
value whose lmt regions will be shared by other secondary
pcifuncs. Here secondary pcifunc will be the one who is
calling the mailbox.
For example:
By default each pcifunc has its own LMT base address:
        PCIFUNC1    LMT_BASE_ADDR A
        PCIFUNC2    LMT_BASE_ADDR B
        PCIFUNC3    LMT_BASE_ADDR C
        PCIFUNC4    LMT_BASE_ADDR D
Application will choose PCIFUNC1 as base/primary pcifunc
and as and when other pcifunc(secondary pcifuncs) gets
probed, this mailbox will be called and LMTST table will
be updated as:
        PCIFUNC1    LMT_BASE_ADDR A
        PCIFUNC2    LMT_BASE_ADDR A

When a switchdev port leaves a LAG that is a bridge port, the switchdev
objects and port attributes offloaded to that port are not removed:

ip link add br0 type bridge
ip link add bond0 type bond mode 802.3ad
ip link set swp0 master bond0
ip link set bond0 master br0
bridge vlan add dev bond0 vid 100
ip link set swp0 nomaster

VLAN 100 will remain installed on swp0 despite it going into standalone
mode, because as far as the bridge is concerned, nothing ever happened
to its bridge port.

Let's extend the bridge vlan, fdb and mdb replay functions to take a
'bool adding' argument, and make DSA and ocelot call the replay
functions with 'adding' as false from the switchdev unsync path, for the
switch port that leaves the bridge.

Note that this patch in itself does not salvage anything, because in the
current pull mode of operation, DSA still needs to call the replay
helpers with adding=false. This will be done in another patch.

There is a slight inconvenience in the switchdev replay helpers added
recently, and this is when:

ip link add br0 type bridge
ip link add bond0 type bond
ip link set bond0 master br0
bridge vlan add dev bond0 vid 100
ip link set swp0 master bond0
ip link set swp1 master bond0

Since the underlying driver (currently only DSA) asks for a replay of
VLANs when swp0 and swp1 join the LAG because it is bridged, what will
happen is that DSA will try to react twice on the VLAN event for swp0.
This is not really a huge problem right now, because most drivers accept
duplicates since the bridge itself does, but it will become a problem
when we add support for replaying switchdev object deletions.

Let's fix this by adding a blank void *ctx in the replay helpers, which
will be passed on by the bridge in the switchdev notifications. If the
context is NULL, everything is the same as before. But if the context is
populated with a valid pointer, the underlying switchdev driver
(currently DSA) can use the pointer to 'see through' the bridge port
(which in the example above is bond0) and 'know' that the event is only
for a particular physical port offloading that bridge port, and not for
all of them.

In the case where the driver asks for a replay of a certain type of
event (port object or attribute) for a bridge port that is a LAG, it may
do so because this port has just joined the LAG.

But there might already be other switchdev ports in that LAG, and it is
preferable that those preexisting switchdev ports do not act upon the
replayed event.

The solution is to add a context to switchdev events, which is NULL most
of the time (when the bridge layer initiates the call) but which can be
set to a value controlled by the switchdev driver when a replay is
requested. The driver can then check the context to figure out if all
ports within the LAG should act upon the switchdev event, or just the
ones that match the context.

We have to modify all switchdev_handle_* helper functions as well as the
prototypes in the drivers that use these helpers too, because these
helpers hide the underlying struct switchdev_notifier_info from us and
there is no way to retrieve the context otherwise.

The context structure will be populated and used in later patches.

The newly implemented fwnode_mdbiobus_register turned out to be

depmod: ERROR: Found 2 modules in dependency cycles!

OR:

depmod: ERROR: Cycle detected: acpi_mdio -> fwnode_mdio -> acpi_mdio

A possible solution could be to rework fwnode_mdiobus_register,
so that to merge the contents of acpi_mdiobus_register and
of_mdiobus_register. However feasible, such change would
be very intrusive and affect huge amount of the of_mdiobus_register
