====================
Fully describe the waveform for PTP periodic output
While using the ancillary pin functionality of PTP hardware clocks to
synchronize multiple DSA switches on a board, a need arised to be able
to configure the duty cycle of the master of this PPS hierarchy.
Also, the PPS master is not able to emit PPS starting from arbitrary
absolute times, so a new flag is introduced to support such hardware
without making guesses.
With these patches, struct ptp_perout_request now basically describes a

ptp: introduce a phase offset in the periodic output request
Some PHCs like the ocelot/felix switch cannot emit generic periodic
output, but just PPS (pulse per second) signals, which:
- don't start from arbitrary absolute times, but are rather
phase-aligned to the beginning of [the closest next] second.
- have an optional phase offset relative to that beginning of the
second.
For those, it was initially established that they should reject any
other absolute time for the PTP_PEROUT_REQUEST than 0.
000000000 [1].
But when it actually came to writing an application [2] that makes use
of this functionality, we realized that we can't really deal generically
with PHCs that support absolute start time, and with PHCs that don't,
without an explicit interface. Namely, in an ideal world, PHC drivers
would ensure that the "perout.start" value written to hardware will
result in a functional output. This means that if the PTP time has
become in the past of this PHC's current time, it should be
automatically fast-forwarded by the driver into a close enough future
time that is known to work (note: this is necessary only if the hardware
doesn't do this fast-forward by itself). But we don't really know what
is the status for PHC drivers in use today, so in the general sense,
user space would be risking to have a non-functional periodic output if
it simply asked for a start time of 0.
000000000.
So let's introduce a flag for this type of reduced-functionality
hardware, named PTP_PEROUT_PHASE. The start time is just "soon", the
only thing we know for sure about this signal is that its rising edge
events, Rn, occur at:
Rn = perout.phase + n * perout.period
The "phase" in the periodic output structure is simply an alias to the
"start" time, since both cannot logically be specified at the same time.
Therefore, the binary layout of the structure is not affected.

ptp: add ability to configure duty cycle for periodic output
There are external event timestampers (PHCs with support for
PTP_EXTTS_REQUEST) that timestamp both event edges.
When those edges are very close (such as in the case of a short pulse),
there is a chance that the collected timestamp might be of the rising,
or of the falling edge, we never know.
There are also PHCs capable of generating periodic output with a
configurable duty cycle. This is good news, because we can space the
rising and falling edge out enough in time, that the risks to overrun
the 1-entry timestamp FIFO of the extts PHC are lower (example: the
perout PHC can be configured for a period of 1 second, and an "on" time
of 0.5 seconds, resulting in a duty cycle of 50%).
A flag is introduced for signaling that an on time is present in the
perout request structure, for preserving compatibility. Logically
speaking, the duty cycle cannot exceed 100% and the PTP core checks for
this.
PHC drivers that don't support this flag emit a periodic output of an
unspecified duty cycle, same as before.
The duty cycle is encoded as an "on" time, similar to the "start" and
"period" times, and reuses the reserved space while preserving overall
binary layout.
Pahole reported before:
struct ptp_perout_request {
struct ptp_clock_time start; /* 0 16 */
struct ptp_clock_time period; /* 16 16 */

icmp: support rfc 4884
Add setsockopt SOL_IP/IP_RECVERR_4884 to return the offset to an
extension struct if present.
ICMP messages may include an extension structure after the original
datagram. RFC 4884 standardized this behavior. It stores the offset
in words to the extension header in u8 icmphdr.un.reserved[1].
The field is valid only for ICMP types destination unreachable, time
exceeded and parameter problem, if length is at least 128 bytes and
entire packet does not exceed 576 bytes.
Return the offset to the start of the extension struct when reading an
ICMP error from the error queue, if it matches the above constraints.
Do not return the raw u8 field. Return the offset from the start of
the user buffer, in bytes. The kernel does not return the network and
transport headers, so subtract those.
Also validate the headers. Return the offset regardless of validation,
as an invalid extension must still not be misinterpreted as part of
the original datagram. Note that !invalid does not imply valid. If
the extension version does not match, no validation can take place,
for instance.
For backward compatibility, make this optional, set by setsockopt
SOL_IP/IP_RECVERR_RFC4884. For API example and feature test, see
github.com/wdebruij/kerneltools/blob/master/tests/recv_icmp_v2.c
For forward compatibility, reserve only setsockopt value 1, leaving
other bits for additional icmp extensions.
Changes
v1->v2:
- convert word offset to byte offset from start of user buffer
- return in ee_data as u8 may be insufficient
- define extension struct and object header structs
- return len only if constraints met
- if returning len, also validate

net: enetc: remove bootloader dependency
These patches were picked from the following series:
https://lore.kernel.org/netdev/
1567779344-30965-1-git-send-email-claudiu.manoil@nxp.com/
They have never been resent. I've picked them up, addressed Andrews
comments, fixed some more bugs and asked Claudiu if I can keep their SOB
tags; he agreed. I've tested this on our board which happens to have a
bootloader which doesn't do the enetc setup in all cases. Though, only
SGMII mode was tested.
changes since v6:
- dropped _LPA_ infix for USXGMII constants
changes since v5:
- fixed pcs->autoneg_complete and pcs->link assignment. Thanks Vladimir.
changes since v4:
- moved (and renamed) the USXGMII constants to include/uapi/linux/mdio.h.
Suggested by Russell King.
changes since v3:
- rebased to latest net-next where devm_mdiobus_free() was removed.
replace it by mdiobus_free(). The internal MDIO bus is optional, if
there is any error, we try to run with the bootloader default PCS
settings, thus in the error case, we need to free the mdiobus.
changes since v2:
- removed SOBs from "net: enetc: Initialize SerDes for SGMII and USXGMII
protocols" because almost everything has changed.
- get a phy_device for the internal PCS PHY so we can use the phy_
functions instead of raw mdiobus writes
- reuse macros already defined in fsl_mdio.h, move missing bits from
felix to fsl_mdio.h, because they share the same PCS PHY building
block
- added 2500BaseX mode (based on felix init routine)
- changed xgmii mode to usxgmii mode, because it is actually USXGMII and
felix does the same.
- fixed devad, which is 0x1f (MMD_VEND2)
changes since v1:
- mdiobus id is '"imdio-%s", dev_name(dev)' because the plain dev_name()
is used by the emdio.
- use mdiobus_write() instead of imdio->write(imdio, ..), since this is
already a full featured mdiobus
- set phy_mask to ~0 to avoid scanning the bus
- use phy_interface_mode_is_rgmii(phy_mode) to also include the RGMII
modes with pad delays.
- move enetc_imdio_init() to enetc_pf.c, there shouldn't be any other
users, should it?
- renamed serdes to SerDes
- printing the error code of mdiobus_register() in the error path
- call mdiobus_unregister() on _remove()
- call devm_mdiobus_free() if mdiobus_register() fails, since an
error is not fatal
