The current mv88e6xxx_smi_direct_wait function is only used to check
the 16th bit of the (16-bit) SMI Command register. But the bit shift
operation is not enough if we eventually use this function to check
other bits, thus replace it with a mask.

Now that we have proper Wait Bit and Wait Mask routines, remove the
unused mv88e6xxx_wait routine and its Global 1 and Global 2 variants.

The indirect tables such as the Device Mapping Table or Priority
Override Table make use of an Update bit to distinguish reading (0)
from writing (1) operations. After a write operation occurs, the bit
self clears right away so there's no need to wait on it. Thus keep
things simple and remove the mv88e6xxx_update helper as well.

The AVB is not an indirect table using an Update bit, but a unit using

Many portions of the driver need to wait until a given bit is set
or cleared. Some busses even have a specific implementation for this
operation. In preparation for such variant, implement a generic Wait
Bit routine that can be used by the driver core functions.

This allows us to get rid of the custom implementations we may find
in the driver. Note that for the EEPROM bits, BUSY and RUNNING bits
are independent, thus it is more efficient to wait independently for
each bit instead of waiting for their mask.

The current mv88e6xxx_wait routine is used to wait for a given mask
to be cleared to zero. However in some cases, the driver may have
to wait for a given mask to be of a certain non-zero value.

Thus provide a generic wait mask routine that will be used to implement
the current mv88e6xxx_wait function, and use it to wait for 88E6185
PPU states.

The PPU state of 88E6185 can be either "Disabled at Reset" or
"Disabled after Initialization". Because we intentionally clear the
PPU Enabled bit before checking its state, it is safe to wait for the
MV88E6185_G1_STS_PPU_STATE_DISABLED state explicitly instead of waiting
for any state different than MV88E6185_G1_STS_PPU_STATE_POLLING.

net: phy: realtek: add support for integrated 2.5Gbps PHY in RTL8125

This series adds support for the integrated 2.5Gbps PHY in RTL8125.
First three patches add necessary functionality to phylib.

Changes in v2:
- added patch 1
- changed patch 4 to use a fake PHY ID that is injected by the
  network driver. This allows to use a dedicated PHY driver.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

This adds support for the integrated 2.5Gbps PHY in Realtek RTL8125.
Advertisement of 2.5Gbps mode is done via a vendor-specific register.
Same applies to reading NBase-T link partner advertisement.
Unfortunately this 2.5Gbps PHY shares the PHY ID with the integrated
1Gbps PHY's in other Realtek network chips and so far no method is
known to differentiate them. As a workaround use a dedicated fake PHY ID
that is set by the network driver by intercepting the MDIO PHY ID read.

v2:
- Create dedicated PHY driver and use a fake PHY ID that is injected by
  the network driver. Suggested by Andrew Lunn.

The integrated PHY in 2.5Gbps chip RTL8125 is the first (known to me)
PHY that uses standard Clause 22 for all modes up to 1Gbps and adds
2.5Gbps control using vendor-specific registers. To use phylib for
the standard part little extensions are needed:
- Move most of genphy_config_aneg to a new function
  __genphy_config_aneg that takes a parameter whether restarting
  auto-negotiation is needed (depending on whether content of
  vendor-specific advertisement register changed).
- Don't clear phydev->lp_advertising in genphy_read_status so that
  we can set non-C22 mode flags before.

Basically both changes mimic the behavior of the equivalent Clause 45
functions.

====================
drop_monitor: Capture dropped packets and metadata

So far drop monitor supported only one mode of operation in which a
summary of recent packet drops is periodically sent to user space as a
netlink event. The event only includes the drop location (program
counter) and number of drops in the last interval.

While this mode of operation allows one to understand if the system is
dropping packets, it is not sufficient if a more detailed analysis is
required. Both the packet itself and related metadata are missing.

This patchset extends drop monitor with another mode of operation where
the packet - potentially truncated - and metadata (e.g., drop location,
timestamp, netdev) are sent to user space as a netlink event. Thanks to
the extensible nature of netlink, more metadata can be added in the
future.

To avoid performing expensive operations in the context in which
kfree_skb() is called, the dropped skbs are cloned and queued on per-CPU
skb drop list. The list is then processed in process context (using a
workqueue), where the netlink messages are allocated, prepared and
finally sent to user space.

A follow-up patchset will integrate drop monitor with devlink and allow
the latter to call into drop monitor to report hardware drops. In the
future, XDP drops can be added as well, thereby making drop monitor the
go-to netlink channel for diagnosing all packet drops.

Example usage with patched dropwatch [1] can be found here [2]. Example
dissection of drop monitor netlink events with patched wireshark [3] can
be found here [4]. I will submit both changes upstream after the kernel
changes are accepted. Another change worth making is adding a dropmon
pseudo interface to libpcap, similar to the nflog interface [5]. This
will allow users to specifically listen on dropmon traffic instead of
capturing all netlink packets via the nlmon netdev.

Patches #1-#5 prepare the code towards the actual changes in later
patches.

Patch #6 adds another mode of operation to drop monitor in which the
dropped packet itself is notified to user space along with metadata.

Patch #7 allows users to truncate reported packets to a specific length,
in case only the headers are of interest. The original length of the
packet is added as metadata to the netlink notification.

Patch #8 allows user to query the current configuration of drop monitor
(e.g., alert mode, truncation length).

Patches #9-#10 allow users to tune the length of the per-CPU skb drop
list according to their needs.

Changes since v1 [6]:
* Add skb protocol as metadata. This allows user space to correctly
  dissect the packet instead of blindly assuming it is an Ethernet
  packet

Changes since RFC [7]:
* Limit the length of the per-CPU skb drop list and make it configurable
* Do not use the hysteresis timer in packet alert mode
* Introduce alert mode operations in a separate patch and only then
  introduce the new alert mode
* Use 'skb->skb_iif' instead of 'skb->dev' because the latter is inside
  a union with 'dev_scratch' and therefore not guaranteed to point to a
  valid netdev
* Return '-EBUSY' instead of '-EOPNOTSUPP' when trying to configure drop
  monitor while it is monitoring
* Did not change schedule_work() in favor of schedule_work_on() as I did
  not observe a change in number of tail drops

So far drop monitor supported only one alert mode in which a summary of
locations in which packets were recently dropped was sent to user space.

This alert mode is sufficient in order to understand that packets were
dropped, but lacks information to perform a more detailed analysis.

Add a new alert mode in which the dropped packet itself is passed to
user space along with metadata: The drop location (as program counter
and resolved symbol), ingress netdevice and drop timestamp. More
metadata can be added in the future.

To avoid performing expensive operations in the context in which
kfree_skb() is invoked (can be hard IRQ), the dropped skb is cloned and
queued on per-CPU skb drop list. Then, in process context the netlink
message is allocated, prepared and finally sent to user space.

The per-CPU skb drop list is limited to 1000 skbs to prevent exhausting

The function reset_per_cpu_data() allocates and prepares a new skb for
the summary netlink alert message ('NET_DM_CMD_ALERT'). The new skb is
stored in the per-CPU 'data' variable and the old is returned.

The function is invoked during module initialization and from the
workqueue, before an alert is sent. This means that it is possible to
receive an alert with stale data, if we stopped tracing when the
hysteresis timer ('data->send_timer') was pending.

Instead of invoking the function during module initialization, invoke it
just before we start tracing and ensure we get a fresh skb.

This also allows us to remove the calls to initialize the timer and the
work item from the module initialization path, since both could have
been triggered by the error paths of reset_per_cpu_data().

This also guarantees that once the request to disable tracing returns,
no more netlink notifications will be generated.

Networking driver debugfs cleanups

There is no need to test the result of any debugfs call anymore.  The
debugfs core warns the user if something fails, and the return value of
a debugfs call can always be fed back into another debugfs call with no
problems.

Also, debugfs is for debugging, so if there are problems with debugfs
(i.e. the system is out of memory) the rest of the kernel should not
change behavior, so testing for debugfs calls is pointless and not the
goal of debugfs at all.

This series cleans up a lot of networking drivers and some wimax code
that was calling debugfs and trying to do something with the return
value that it didn't need to.  Removing this logic makes the code
smaller, easier to understand, and use less run-time memory in some
cases, all good things.

The series is against net-next, and have no dependancies between any of
them if they want to go through any random tree/order.  Or, if wanted,
I can take them through my driver-core tree where other debugfs cleanups
are being slowly fed during major merge windows.

v3: fix build warning in i2400m, I thought I had caught them all :(
    add acks from some reviewers

v2: fix up build warnings, it's as if I never even built these.  Ugh, so
    sorry for wasting people's time with the v1 series.  I need to stop
    relying on 0-day as it isn't working well anymore :(
