The check for zero timeout is always true at the end of the proceeding
while loop; the only other exit path in the loop is if the unimac MDIO
is not busy. Remove the redundant zero timeout check and always
return -ETIMEDOUT on this timeout return path.

1000BaseT standard requires that a link is reported as down earliest
after 750ms. Several use case however require a much faster detecion
of a broken link. Fast Link Down supports this by intentionally
violating a the standard. This patch exposes the Fast Link Down
feature of 88E1540 and 88E6390. These PHY's can be found as internal
PHY's in several switches: 88E6352, 88E6240, 88E6176, 88E6172,
and 88E6390(X). Fast Link Down and EEE are mutually exclusive.

====================
100GbE Intel Wired LAN Driver Updates 2019-03-26
This series contains more updates to the ice driver only.
Jeremiah provides his first patch to the Linux kernel to clean up
un-necessary newlines in driver log messages.
Mitch updates the ice driver to use existing status codes in the iavf
driver so that when errors occur, it will not report nonsensical
results. Adds support for VF admin queue interrupts by programming the
VPINT_MBX_CTL register array.
Brett adds a check for a bit that we set while preparing for a reset, to
ensure we are prepared to do a proper reset. Also implemented PCI error
handling operations. Went through and audited the hot path with pahole
and made modifications based on the results since 2 structures were
taking up more space than necessary due to cache alignment issues.
Fixed an issue where when flow control was disabled, the state of flow
control was being displayed as "Unknown".
Anirudh fixes adaptive interrupt moderation changes by adding code that
was missed, that should have been added in the initial patch to add that
support. Cleaned up a function prototype that was never implemented.
Did additional code cleanup by removing unneeded braces and redundant
code comments.
Akeem fixes an issue that occurs when the VF is attempting to remove the
default LAN/MAC address, which is programmed by the administrator by
updating the error message to explicitly say that the VF cannot change
the MAC programmed by the PF.
Preethi fixes the driver to not fall into the error path when a added
filter already exists, but instead continue to process the rest of the
function and add appropriate checks after adding MAC filters.

The C2 classification engine has a 256 entry TCAM, used for ternary
matches on an 8 byte Header Extracted Key. For now, we compute the
various indices for classification and RSS that use this engine thanks
to a set of macros.
This commit mainly renames the macros used to make it clear that they
should be used with the C2 engine, but also make use of the full 256
entries in the engine. For now, the C2 entries are only used for RSS.
These entries are put at the end of the TCAM range, in case we want to
add higher priority matches later on.

When classifying a packet pertaining to a given flow, the classifier
will issue multiple lookup commands until it finds one with the 'last'
bit set. It expects all prorities to be assign continuously (although
not necessarily in an ordered fashion) from 0 to the number of lookups.
We can initialize this once, and make sure unused lookups are given an
empty port map. This avoids having to maintain priorities and the
information of which lookup is the last.

The Flow Table dictates what lookups will be issued for each flow type.
The lookup sequence for each flow is similar, and the index of each
lookup is computed by some macros.
There are similar mechanisms for the C2 TCAM lookups, so in order to
avoid confusion, rename the flow table index computing macros with a
common prefix.
The only difference in behaviour is that we now use the very first entry
in the flow for the RSS lookup (the first entry was previously unused).

The classifier allows to combine multiple lookups in one "sequence" that

The cls_table is a global read-only table containing the different
parameters that are used by various tables in the classifier. It
describes the links between the Header Parser, the decoding table and
the flow_table.
There are several possible way we want to iterate over that table,
depending on wich classifier engine we want to configure. For the Header
Parser, we want to iterate over each entry. For the Decoding table, we
want to iterate over each entry having a unique flow_id. Finally, when
configuring an ethtool flow, we want to iterate over each entry having a
unique flow_id and that has a given flow_type.
This commit introduces some iterator to both provide syntactic sugar and
also clarify the way we want to iterate over the table.

PPv2's Classifier uses multiple engines to perform classification. So
far, only the C2 engine is used, which has a 256 entries TCAM.
So far, we only accessed the relevant entries from the C2 engines, which
are the one implementing RSS. To implement and debug ntuple
classification offload, beaing able to see the hit count for each C2
entry is helpful, so this commit moves the logic to a dedicated
directory allowing to access each entry.

The Classifier flow table is the central part of the PPv2 Classifier,
since it describes all classification steps performed for each flow.
It has 512 entries, shared between all ports, which are divided into
sequences that are pointed-to by the decoding table. Being able to see
which entries in the flow table were hit is a key point when
implementing and debugging classification offload.
This commit allows reading each flow table entry's hit count
independently, with a clear-on-read behaviour.

The current way to store the required private data needed to access
various debugfs entries is to alloc them on the fly, share them within
the entries that need to access them, and finally have one entry free
that data upon closing. This leads to hard to maintain code, and is very
error-prone.
This commit stores all debugfs related data in the same place, making
sure this is allocated only when the debugfs directory is successfully
created, so that we don't waste memory when we don't use this feature.

The PPv2 classifier allows to perform multiple lookups on the same
engine when classifying a packet. These lookups can match similar parts
of a packet header, but perform different actions upon matching. To
differentiate these types of lookups, it's possible to specify a Lookup
Type in the flow table entries, which will be part of the key for the
lookup engines.
This commit introduces the use of Lookup Types for C2 matches. Since for
now we only perform C2 lookups to enable RSS, we only need one Lookup
Type.

The Classifier flow table has 512 entries, that contains lookups
commands executed consecutively for every flow. Since we have 21
different flows, we have to carefully manage the flow table use.
As of today, the start index of a lookup sequence is computed
directly based in the flow->id. There are 8 reserved flow ids, from
0-7, which don't have any corresponding sequence in the flow table. We
can therefore ignore them when computing the index, and make so that the
first non-reserved flow point to the very beginning of the flow table.

Currently the ice_q_vector structure and ice_ring_container structure
are taking up more space than necessary due to cache alignment holes
and unnecessary variables respectively. This is not helping the
driver's performance. The following fixes were done to improve cache
alignment, reduce wasted space, and increase performance.
1. Remove the ice_latency_range enum as it is unused.
2. Remove the latency_range variable in the ice_ring_container structure.
3. Change the size of the itr_idx in the ice_ring_container structure
from an int to an u16. This reduced the size of ice_ring_container
structure to 32 Bytes so it has no holes or padding.
4. Re-arrange the ice_q_vector structure using pahole to align
members as best as possible in regards to 64 Byte cache line size.

Previously the green and amber LEDs on this quad PHY were solid, to
indicate an encoding of the link speed (10/100/1000).
This keeps the LEDs always on just as before, but now they flash on
Rx/Tx activity.

This patch implements accessors for the QCA8337 MDIO access
through the MDIO_MASTER register, which makes it possible to
access the PHYs on slave-bus through the switch. In cases
where the switch ports are already mapped via external
"phy-phandles", the internal mdio-bus is disabled in order to
prevent a duplicated discovery and enumeration of the same
PHYs. Don't use mixed external and internal mdio-bus
configurations, as this is not supported by the hardware.
