The phy core provides a handy phy_speed_to_str() helper, so use that
instead of doing our own formatting of the different known link speeds.
To do this, increase PHY_LED_TRIGGER_SPEED_SUFFIX_SIZE to 11 so we can fit
'Unsupported' if necessary.

As a heritage from the very early days of phylib member interrupts is
defined as u32 even though it's just a flag whether interrupts are
enabled. So we can change it to a bitfield member. In addition change
the code dealing with this member in a way that it's clear we're
dealing with a bool value.

====================
More accurate PHC<->system clock synchronization
RFC->v1:
- added new patches
- separated PHC timestamp from ptp_system_timestamp
- fixed memory leak in PTP_SYS_OFFSET_EXTENDED
- changed PTP_SYS_OFFSET_EXTENDED to work with array of arrays
- fixed PTP_SYS_OFFSET_EXTENDED to break correctly from loop
- fixed timecounter updates in drivers
- split gettimex in igb driver
- fixed ptp_read_* functions to be available without
CONFIG_PTP_1588_CLOCK
This series enables a more accurate synchronization between PTP hardware
clocks and the system clock.
The first two patches are minor cleanup/bug fixes.
The third patch adds an extended version of the PTP_SYS_OFFSET ioctl,
which returns three timestamps for each measurement. The idea is to
shorten the interval between the system timestamps to contain just the
reading of the lowest register of the PHC in order to reduce the error
in the measured offset and get a smaller upper bound on the maximum
error.
The fourth patch deprecates the original gettime function.
The remaining patches update the gettime function in order to support
the new ioctl in the e1000e, igb, ixgbe, and tg3 drivers.
Tests with few different NICs in different machines show that:
- with an I219 (e1000e) the measured delay was reduced from 2500 to 1300
ns and the error in the measured offset, when compared to the cross
timestamping supported by the driver, was reduced by a factor of 5
- with an I210 (igb) the delay was reduced from 5100 to 1700 ns
- with an I350 (igb) the delay was reduced from 2300 to 750 ns
- with an X550 (ixgbe) the delay was reduced from 1950 to 650 ns
- with a BCM5720 (tg3) the delay was reduced from 2400 to 1200 ns

The PTP_SYS_OFFSET ioctl, which can be used to measure the offset
between a PHC and the system clock, includes the total time that the
driver needs to read the PHC timestamp.
This typically involves reading of multiple PCI registers (sometimes in
multiple iterations) and the register that contains the lowest bits of
the timestamp is not read in the middle between the two readings of the
system clock. This asymmetry causes the measured offset to have a
significant error.
Introduce a new ioctl, driver function, and helper functions, which
allow the reading of the lowest register to be isolated from the other
readings in order to reduce the asymmetry. The ioctl returns three
timestamps for each measurement:
- system time right before reading the lowest bits of the PHC timestamp
- PHC time
- system time immediately after reading the lowest bits of the PHC
timestamp

====================
hns3: add code optimization for VF reset and some new reset feature
Currently hardware supports below reset:
1. VF reset: triggered by sending cmd to IMP(Integrated Management
Processor). Only reset specific VF function and do not affect
other PF or VF.
2. PF reset: triggered by sending cmd to IMP. Only reset specific PF
and it's VF.
3. PF FLR: triggered by PCIe subsystem. Only reset specific PF and
it's VF.
4. VF FLR: triggered by PCIe subsystem. Only reset specific VF function
and do not affect other PF or VF.
5. Core reset: triggered by writing to register. Reset most hardware
unit, such as SSU, which affects all the PF and VF.
6. Global reset: triggered by writing to register. Reset all hardware
unit, which affects all the PF and VF.
7. IMP reset: triggered by IMU(Intelligent Management Unit) when
IMP is not longer feeding IMU's watchdog. IMU will reload the IMP
firmware and IMP will perform global reset after firmware reloading,
which affects all the PF and VF.
Current driver only support PF/VF reset, incomplete core and global
reset(lacking the vf reset handling). So this patchset adds complete
reset support in hns3 driver.
Also, this patchset contains some optimization related to reset.

This patch implements the .reset_prepare and .reset_done
ops from pci framework to support the VF FLR.
This patch uses hclgevf_set_def_reset_request() and
hclgevf_reset_event() to handle FLR, so when
hdev->default_reset_request is non zero, it means there is
some reset requseted by hclgevf_set_def_reset_request() need
to be processed. Also get the hdev from the ae_dev because
hclgevf_reset_event is called with handle being NULL.

The current code only print the prompt message after receiving
the IMP reset interrupt and does not perform the corresponding driver
reset operation. This patch implements the missing IMP reset handling
in the driver.
1. The driver sets the HCLGE_STATE_CMD_DISABLE to stop sending command
after receiving the IMP reset interrupt.
2. The driver needs to notify the hardware to reload the IMP firmware.
3. The IMP firmware reloading makes the reset time of hardware longer,
so it is necessary to extend the driver's waiting time to wait for
the hardware reset to complete.
4. In hclge_check_event_cause, IMP reset event should have higher
priority than other events.
Also, after clearing HCLGE_STATE_CMD_DISABLE in the hclge_cmd_init(),
it needs to check whether there is a pending reset, if so, just set
the HCLGE_STATE_CMD_DISABLE back and return.

When calling napi_disable during reset down process, if NAPIF_STATE_MISSED
is set, napi_complete will call __napi_schedule to do the polling again.
So this patch uses HNS3_NIC_STATE_DOWN to ensure the polling is not

Also, when napi_complete returns true, it means polling is scheduled

Since hclgevf_reset() may fail for some reasons, so it needs an error
handler to deal with it. When VF reset failed, VF can only be restored
by a higher level reset asserted by PF. So, it needs to reinitialize
its command queue, then it can respond to higher level reset.
Also, this patch adds error logging in the hclgevf_notify_client().

According to hardware's description, after the reset occurs, the driver

not allow sending or receiving commands before the re-initialization.

When a Core/Global/IMP reset occurs, the hardware sets the reset status
register of all PF/VF and reports a reset interrupt to all PF/VF and
firmware.
When receiving the reset interrupt:
1. The firmware will wait for 100 ms before resetting the hardware and
clear the reset status register of all PF when hardware reset is done.
2. The PF/VF driver needs to down the netdev within 100 ms and then wait
for hardware reset to finish.
3. After firmware clearing the reset status register of all PF, the PF
driver reinitializes the hardware and clear the reset status register
of it's VF.
4. After PF driver clearing the reset status register of VF, the VF driver
reinitializes the hardware.
This patch mainly add handling for the step 4.

When PF performs a function reset, the hardware will reset both PF
and all the VF belong to this PF. Hence, both PF's driver and VF's
driver need to perform corresponding reset operations.
Before PF driver asserting function reset to hardware, it firstly
set up VF's hardware reset status, and inform the VF driver with
HNAE3_VF_PF_FUNC_RESET, then VF driver sets this reset type to
reset_pending and shechule reset task to stop IO and waits for the
hardware reset status to clear. When PF driver has reinitialized the
hardware and is ready to process mailbox from VF, PF driver clears
VF's hardware reset status for VF to continue its reset process.
Also, this patch uses readl_poll_timeout to simplify the hardware reset
status waitting.

Currently when VF need to reset itself, it will send a cmd to PF,
after receiving the VF reset requset, PF sends a cmd to inform
VF to enter the reset process and send a cmd to firmware to do the
actual reset for the VF, it is possible that firmware has resetted
the VF, but VF has not entered the reset process, which may cause
IO not stopped problem when firmware is resetting VF.
This patch fixes it by adjusting the VF reset process, when VF
need to reset itself, it will enter the reset process first, and
it will tell the PF to send cmd to firmware to reset itself.
Add member reset_pending to struct hclgevf_dev, which indicates that
there is reset event need to be processed by the VF's reset task, and
the VF's reset task chooses the highest-level one and clears other
low-level one when it processes reset_pending.
hclge_inform_reset_assert_to_vf function is unused now, but it will
be used to support the PF reset with VF working, so declare it in
the header file.

reinitialize hardware, it makes sense to add a function to
do that job. Also the error handling of hclgevf_init_hdev is

====================
nfp: abm: move code and improve parameter validation
This set starts by separating Qdisc handling code into a new file.
Next two patches allow early access to TLV-based capabilities during
probe, previously the capabilities were parsed just before netdevs
were registered, but its cleaner to do some basic validation earlier
and avoid cleanup work.
Next three patches improve RED's parameter validation. First we provide
a more precise message about why offload failed (and move the parameter
validation to a helper). Next we make sure we don't set the top bit
in the 32 bit max RED threshold value. Because FW is treating the value
as signed it reportedly causes slow downs (unnecessary queuing and
marking) when top bit is set with recent firmwares. Last (and perhaps
least importantly) we offload the harddrop parameter of the Qdisc.
We don't plan to offload harddrop RED, but it seems prudent to make
sure user didn't set that flag as device behaviour would have differed.

In certain cases initialization logic which follows allocation of
the vNIC structure may want to validate the capabilities of that vNIC.
This is easy before vNIC is initialized for normal capabilities which
are at fixed offsets in control memory, easy to locate and read, but
poses a challenge if the capabilities are in form of TLVs. Parse
the TLVs early on so other code can just access parsed info, instead
of having to do the parsing by itself.
