On various critical errors, notification handler should also report
the err information into the management firmware.
MFW can interact with server/motherboard backend agents - these are
used by server manufacturers to monitor server HW health.
Thus, it is important for driver to report on any faulty conditions

qede (ethernet level driver) registers a callback handler.
This handler maintains eth dev state flags/bits to track error processing.
It implements in place processing part for nonsleeping context (WARN_ON
trigger), and a deferred (delayed work) part which triggers recovery
process for recoverable errors.
In later patches this atomic handler will come with more meat.
We introduce err_flags on ethdevice structure, its being used to record
error handling properties.

which causes iproute2 tc to emit additional "parent ffff:" in first line of

Currently, setting a bridge's self PVID to other value and deleting
the default VID 1 renders untagged ports of that VLAN unable to talk to
the CPU port:
bridge vlan add dev br0 vid 2 pvid untagged self
bridge vlan del dev br0 vid 1 self
bridge vlan add dev sw0p0 vid 2 pvid untagged
bridge vlan del dev sw0p0 vid 1
# br0 cannot send untagged frames out of sw0p0 anymore
That is because the CPU port is set to security mode and its PVID is
still 1, and untagged frames are dropped due to VLAN member violation.
Set the CPU port to fallback mode so untagged frames can pass through.

Some PHYs connected to this ethernet hardware support the WoL feature.
But when WoL is enabled and the machine is powered off, the PHY remains
waiting for a magic packet at max speed (i.e. 1Gbps), which is a waste of
energy.
Slow down the PHY speed before stopping the ethernet if WoL is enabled,
and save some energy while the machine is powered off or sleeping.

The AR8031/AR8033 and the AR8035 support cable diagnostics. Adding
driver support is straightforward, so lets add it.
The PHY just do one pair at a time, so we have to start the test four
times. The cable_test_get_status() can block and therefore we can just
busy poll the test completion and continue with the next pair until we
are done.
The time delta counter seems to run at 125MHz which just gives us a
resolution of about 82.4cm per tick.

Most modern broadcom PHYs support ECD (enhanced cable diagnostics). Add
support for it in the bcm-phy-lib so they can easily be used in the PHY
driver.
There are two access methods for ECD: legacy by expansion registers and
via the new RDB registers which are exclusive. Provide functions in two
variants where the PHY driver can choose from. To keep things simple for
now, we just switch the register access to expansion registers in the
RDB variant for now. On the flipside, we have to keep a bus lock to
prevent any other non-legacy access on the PHY.
The results of the intra-pair tests are inconclusive (at least for the
BCM54140). Most of the times half the length is reported but sometimes
the length is correct.

Add helper to read and write expansion registers without taking the mdio
lock.
Please note, that this changes the semantics of the read and write.
Before there was no lock between selecting the expansion register and
the actual read/write. This may lead to access failures if there are
parallel accesses. Instead take the bus lock during the whole access

Add initial cable testing support.
This PHY needs only 100usec for this test and it is recommended to run it
before the link is up. For now, provide at least ethtool support, so it
can be tested by more developers.
This patch was tested with TJA1102 PHY with following results:
- No cable, is detected as open
- 1m cable, with no connected other end and detected as open
- a 40m cable (out of spec, max lenght should be 15m) is detected as OK.
Current patch do not provide polarity test support. This test would
indicate not proper wire connection, where "+" wire of main phy is
connected to the "-" wire of the link partner.

====================
dwmac-meson8b Ethernet RX delay configuration
The Ethernet TX performance has been historically bad on Meson8b and
Meson8m2 SoCs because high packet loss was seen. I found out that this
was related (yet again) to the RGMII TX delay configuration.
In the process of discussing the big picture (and not just a single
patch) [0] with Andrew I discovered that the IP block behind the
dwmac-meson8b driver actually seems to support the configuration of the
RGMII RX delay (at least on the Meson8b SoC generation).
Since I sent the first RFC I got additional documentation from Jianxin
(many thanks!). Also I have discovered some more interesting details:
- Meson8b Odroid-C1 requires an RX delay (by either the PHY or the MAC)
Based on the vendor u-boot code (not upstream) I assume that it will
be the same for all Meson8b and Meson8m2 boards
- Khadas VIM2 seems to have the RX delay built into the PCB trace
length. When I enable the RX delay on the PHY or MAC I can't get any
data through. I expect that we will have the same situation on all
GXBB, GXM, AXG, G12A, G12B and SM1 boards. Further clarification is
needed here though (since I can't visually see these lengthened
traces on the PCB). This will be done before sending patches for
these boards.
Dependencies for this series:
There is a soft dependency for patch #2 on commit f22531438ff42c
"dt-bindings: net: dwmac: increase 'maxItems' for 'clocks',
'clock-names' properties" which is currently in Rob's -next tree.
That commit is needed to make the dt-bindings schema validation
pass for patch #2. That patch has been for ~4 weeks in Robs tree,
so I assume that is not going to be dropped.
Changes since RFC v2 at [2]:
- dropped $ref: /schemas/types.yaml#definitions/uint32 from the
"amlogic,rx-delay-ns" in patch #1 ("Don't need to define the
type when in standard units." says Rob - thanks, I learned
something new). Also use "default: 0" for for this property
instead of explaining it in the description text.
- added a note to the cover-letter about a hidden dependency for
dt-binding schema validation in patch #2
- Added Andrew's Reviewed-by to patches 1-7. Thank you again for
the quick and detailed reviews, I appreciate this!
- error out if the (optional) timing-adjustment clock is missing
but we're asked to enable the RGMII RX delay. The MAC won't
work in this specific case and either the RX delay has to be
provided by the PHY or the timing-adjustment clock has to be
added.
- dropped the dts patches (#9-11) which were only added to give
an overview how this is going to be used. those will be sent
separately
- dropped the RFC prefix
Changes since RFC v1 at [1]:
- add support for the timing adjustment clock input (dt-bindings and
in the driver) thanks to the input from the unnamed Ethernet engineer
at Amlogic. This is the missing link between the fclk_div2 clock and
the Ethernet controller on Meson8b (no traffic would flow if that
clock was disabled)
- add support fot the amlogic,rx-delay-ns property. The only supported
values so far are 0ns and 2ns. The registers seem to allow more
precise timing adjustments, but I could not make that work so far.
- add more register documentation (for the new RX delay bits) and
unified the placement of existing register documentation. Again,
thanks to Jianxin and the unnamed Ethernet engineer at Amlogic
- DO NOT MERGE: .dts patches to show the conversion of the Meson8b
and Meson8m2 boards to "rgmii-id". I didn't have time for all arm64
patches yet, but these will switch to phy-mode = "rgmii-txid" with
amlogic,rx-delay-ns = <0> (because the delay seems to be provided by
the PCB trace length).

Configure the PRG_ETH0_ADJ_* bits to enable or disable the RX delay
based on the various RGMII PHY modes. For now the only supported RX
delay settings are:
- disabled, use for example for phy-mode "rgmii-id"
- 0ns - this is treated identical to "disabled", used for example on
boards where the PHY provides 2ns TX delay and the PCB trace length
already adds 2ns RX delay
- 2ns - for whenever the PHY cannot add the RX delay and the traces on
the PCB don't add any RX delay
Disabling the RX delay (in case u-boot enables it, which is the case
for example on Meson8b Odroid-C1) simply means that PRG_ETH0_ADJ_ENABLE,
PRG_ETH0_ADJ_SETUP, PRG_ETH0_ADJ_DELAY and PRG_ETH0_ADJ_SKEW should be
disabled (just disabling PRG_ETH0_ADJ_ENABLE may be enough, since that
disables the whole re-timing logic - but I find it makes more sense to
clear the other bits as well since they depend on that setting).
u-boot on Odroid-C1 uses the following steps to enable a 2ns RX delay:
- enabling enabling the timing adjustment clock
- enabling the timing adjustment logic by setting PRG_ETH0_ADJ_ENABLE
- setting the PRG_ETH0_ADJ_SETUP bit
The documentation for the PRG_ETH0_ADJ_DELAY and PRG_ETH0_ADJ_SKEW
registers indicates that we can even set different RX delays. However,
I could not find out how this works exactly, so for now we only support
a 2ns RX delay using the exact same way that Odroid-C1's u-boot does.

The timing adjustment clock will need similar logic as the RGMII clock:
It has to be enabled in the driver conditionally and when the driver is
unloaded it should be disabled again. Extract the existing code for the
RGMII clock into a new function so it can be re-used.

The PRG_ETHERNET registers have a built-in timing adjustment circuit
which can provide the RX delay in RGMII mode. This is driven by an
external (to this IP, but internal to the SoC) clock input. Fetch this
clock as optional (even though it's there on all supported SoCs) since
we just learned about it and existing .dtbs don't specify it.

Whenever we disconnect a L2CAP connection, we would immediately
report a disconnection event (EPOLLHUP) to the upper layer, without
waiting for the response of the other device.
This patch offers an option to wait until we receive a disconnection
response before reporting disconnection event, by using the "how"
parameter in l2cap_sock_shutdown(). Therefore, upper layer can opt
to wait for disconnection response by shutdown(sock, SHUT_WR).
This can be used to enforce proper disconnection order in HID,
where the disconnection of the interrupt channel must be complete
before attempting to disconnect the control channel.

After sending Inquiry Cancel command to the controller, it is possible
that Inquiry Complete event comes before Inquiry Cancel command complete
event. In this case the Inquiry Cancel command will have status of
Command Disallowed since there is no Inquiry session to be cancelled.
This case should not be treated as error, otherwise we can reach an
inconsistent state.
Example of a btmon trace when this happened:
< HCI Command: Inquiry Cancel (0x01|0x0002) plen 0
> HCI Event: Inquiry Complete (0x01) plen 1
Status: Success (0x00)
> HCI Event: Command Complete (0x0e) plen 4
Inquiry Cancel (0x01|0x0002) ncmd 1
Status: Command Disallowed (0x0c)

Implement the prevent_wake hook by checking device_may_wakeup on the usb
interface. This prevents the Bluetooth core from enabling scanning when
the device isn't expected to wake from suspend.

Let drivers have a hook to disable configuring scanning during suspend.
Drivers should use the device_may_wakeup function call to determine
whether hci should be configured for wakeup.
For example, an implementation for btusb may look like the following:
bool btusb_prevent_wake(struct hci_dev *hdev)
{
struct btusb_data *data = hci_get_drvdata(hdev);
return !device_may_wakeup(&data->udev->dev);
}

When a device is suspended, it doesn't need to be as responsive to
connection events. Increase the interval to 640ms (creating a duty cycle
of roughly 1.75%) so that passive scanning uses much less power (vs
previous duty cycle of 18.75%). The new window + interval combination
has been tested to work with HID devices (which are currently the only
devices capable of wake up).

A comparison between a value from the packet and an integer constant
value needs to be done by converting the value from the packet from
net->host, or the constant from host->net. Not the other way around.
Even though it makes no practical difference, correct that.
