Commit d068ca2a ("codel: split into multiple files") moved all
Qdisc-related code to codel_qdisc.h, move the include of pkt_sched.h
as well.

This is similar to the previous commit, although we don't care as
much about incremental builds after pkt_sched.h was touched itself
it is included by net/sch_generic.h which is modified ~20 times
a year.

Since sock.h is modified relatively often (60 times in the last
12 months) it seems worthwhile to decrease the incremental build
work.

CoDel's header includes net/inet_ecn.h which in turn includes net/sock.h.
codel.h is itself included by mac80211 which is included by much of
the WiFi stack and drivers. Removing the net/inet_ecn.h include from
CoDel breaks the dependecy between WiFi and sock.h.

Commit d068ca2a ("codel: split into multiple files") moved all
the code which actually needs ECN helpers out to net/codel_impl.h,
the include can be moved there as well.

This decreases the incremental build size after touching sock.h

100GbE Intel Wired LAN Driver Updates 2021-12-21

This series contains updates to ice driver only.

Karol modifies the reset flow to correct issues with PTP reset.

Jake extends PTP support for E822 based devices. This includes a few
cleanup patches, that fix some minor issues. In addition, there are some
slight refactors to ease the addition of E822 support, followed by adding
the new hardware implementation ice_ptp_hw.c.

There are a few major differences with E822 support compared to E810
support:

*) The E822 device has a Clock Generation Unit which must be initialized in
order to generate proper clock frequencies on the output that drives the PTP
hardware clock registers

*) The E822 PHY is a bit different and requires a more complex
initialization procedure which must be rerun any time the link configuration
changes.

*) The E822 devices support enhanced timestamp calibration by making use of
a process called Vernier offset measurement. This allows the hardware to
measure phase offset related to the PHY clocks for Serdes and FEC, reducing
the inaccuracy of the timestamp relative to the actual packet transmission
and receipt. Making use of this requires data gathered from the first
transmitted and received packets, and waiting for the PHY to complete the
calibration measurements. This is done as part of a new kthread, ov_work.
Note that to avoid delay in enabling timestamps, we start the PHY in
'bypass' mode which allows timestamps to be captured without the Vernier
calibration measurement. Once the first packets have been sent and received,
we then complete the calibration setup and exit bypass mode and begin using
the more precise timestamps. According to the datasheet, timestamps without
calibration data can be incorrect relative to actual receipt or transmission
by up to 1 clock cycle (~1.25 nanoseconds), while calibrated timestamps
should be correct to within 1/8th of a clock cycle (~0.15 nanoseconds).

*) E822 devices support crosstimestamping via PCIe PTM, which we enable when
available on the platform.

There is a fair amount of logic required to perform PHY and CGU
initialization, which is the vast majority of the new code, but it is fairly
self contained within ice_ptp_hw.c, with the exception of monitoring for
offset validity being handled by a kthread.

  ice: support crosstimestamping on E822 devices if supported

E822 devices on supported platforms can generate a cross timestamp
between the platform ART and the device time. This process allows for
very precise measurement of the difference between the PTP hardware
clock and the platform time.

This is only supported if we know the TSC frequency relative to ART, so
we do not enable this unless the boot CPU has a known TSC frequency (as
required by convert_art_ns_to_tsc).

Because PCIe PTM support is not available on all platforms, introduce
CONFIG_ICE_HWTS and make it depend on X86 where we know the support
exists.

Once the E822 device has sent and received one packet, the hardware
computes the internal delay of the PHY using a process known as Vernier
calibration. This calibration calculates a more accurate offset for the
Tx and Rx timestamps. To make use of this offset, we need to exit the
bypass mode. This cannot be done until the PHY has completed offset
calibration, as indicated by the offset valid bits.

To handle this, introduce a kthread work item which will poll the offset
valid bits every few milliseconds seeing if it is safe to exit bypass
mode.

Once we have finished calibrating the offsets, we can program the total
Tx and Rx offset registers and turn off the bypass bit. This allows the
hardware to include the more precise vernier calibration offset, and
improves the timestamp precision.

This includes implementations for the various PHY access functions, as
well as the ability to start and stop the PHY timers. This is different

When we enable support for E822 devices, there are some additional
steps required to initialize the PTP hardware clock. To make this easier
to implement as device-specific behavior, refactor the register setups
in ice_ptp_init_owner to a new ice_ptp_init_phc function defined in
ice_ptp_hw.c

This function will have a common section, and an e810 specific
sub-implementation.

This will enable easily extending the functionality to cover the E822
specific setup required to initialize the hardware clock generation
unit. It also makes it clear which steps are E810 specific vs which ones
are necessary for all ice devices.

The ice_ptp_hw.c file introduced a bunch of uses of "int status" instead
of the more traditional "int err" or "int ret". These are actually
traditional Linux error codes (as opposed to the recently removed
ice_status enumeration values).

We're about to add a bunch of new functions to ice_ptp_hw.c. It's
normally preferred in the ice driver to use "int ret" or "int err" when
dealing with error code values.

Instead of making the new functions use "int status" lets just fix all
of ice_ptp_hw.c to use "int err". This will match the new functions and
ensures a consistent style across at least the PTP related files.

The tstamp_config structure is being set inside of
ice_ptp_cfg_timestamp, which is the function used to set Tx and
Rx timestamping during initialization.

This function is also used in order to set the PHY port timestamping
status. However, it makes sense to always set the tstamp_config directly
whenever the ice_set_tx_tstamp or ice_set_rx_tstamp functions are
called.

Move assignment of tstamp_config into the related functions and out of
ice_ptp_cfg_timestamp.

Now that we assign the timestamp mode in the relevant functions, we no
longer modify the config value in ice_set_timestamp_mode. In turn, we
no longer want to copy that config value into the PF cached structure.
Instead, this is now the source of truth for actual configuration. On
success of ice_set_timestamp_mode, copy the real configured mode back to
report it out to userspace.

The previously reserved bits are now being used which
then requires the adjustment to the BIT values, e.g.:

   PORT_PROPERTY_0[26:23] - Supported Speeds

After:
   PORT_PROPERTY_0[21] - Reserved

net: lan966x: Add switchdev and vlan support

This patch series extends lan966x with switchdev and vlan support.
The first patches just adds new registers and extend the MAC table to
handle the interrupts when a new address is learn/forget.

v7->v8:
- remove extra mac learn when the port leaves the bridge
- replace memcpy with ether_addr_copy
- change the order of operations in lan966x_switch_driver_init/exit
- refactor lan966x_port_bridge_flags

v6->v7:
- fix build issues when compiling as a module

v5->v6:
- fix issues with the singletones, they were not really singletons
- simplify the case where lan966x ports are added to bridges with foreign
  ports
- drop the cases NETDEV_PRE_UP and NETDEV_DOWN
- fix the change of MAC address
- drop the callbacks .ndo_set_features, .ndo_vlan_rx_add_vid,
  .ndo_vlan_rx_kill_vid
- remove duplicate code when port was added in a vlan, the MAC entries
  will be added by the fdb

v4->v5:
- make the notifier_block from lan966x to be singletones
- use switchdev_handle_port_obj_add and switchdev_handle_fdb_event_to_device
  when getting callbacks in the lan966x
- merge the two vlan patches in a single one

v3->v4:
- split the last patch in multiple patches
- replace spin_lock_irqsave/restore with spin_lock/spin_unlock
- remove lan966x_port_change_rx_flags because it was copying all the frames to
  the CPU instead of removing all RX filters.
- implement SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS
- remove calls to __dev_mc_unsync/sync as they are not needed
- replace 0/1 with false/true
- make sure that the lan966x ports are not added to bridges that have other
  interfaces except lan966x
- and allow the lan966x ports to be part of only the same bridge.

v2->v3:
- separate the PVID used when the port is in host mode or vlan unaware
- fix issue when the port was leaving the bridge

v1->v2:
- when allocating entries for the mac table use kzalloc instead of
  devm_kzalloc
- also use GFP_KERNEL instead of GFP_ATOMIC, because is never called
  in atomic context
- when deleting an mac table entry, the order of operations was wrong
- if ana irq is enabled make sure it gets disabled when the driver is
  removed
