The DP83822 can be configured to use the RGMII interface. There are
independent fixed 3.5ns clock shift (aka internal delay) for the TX and RX
paths. This allow either one to be set if the MII interface is RGMII and
the value is set in the firmware node.

net: bridge: fdb activity tracking
This set adds extensions needed for EVPN multi-homing proper and
efficient mac sync. User-space (e.g. FRR) needs to be able to track
non-dynamic entry activity on per-fdb basis depending if a tracked fdb is
currently peer active or locally active and needs to be able to add new
peer active fdb (static + track + inactive) without refreshing it to get
real activity tracking. Patch 02 adds a new NDA attribute - NDA_FDB_EXT_ATTRS
to avoid future pollution of NDA attributes by bridge or vxlan. New
bridge/vxlan specific fdb attributes are embedded in NDA_FDB_EXT_ATTRS,
which is used in patch 03 to pass the new NFEA_ACTIVITY_NOTIFY attribute
which controls if an fdb should be tracked and also reflects its current
state when dumping. It is treated as a bitfield, current valid bits are:
1 - mark an entry for activity tracking
2 - mark an entry as inactive to avoid multiple notifications and
reflect state properly
Patch 04 adds the ability to avoid refreshing an entry when changing it
via the NFEA_DONT_REFRESH flag. That allows user-space to mark a static
entry for tracking and keep its real activity unchanged.
The set has been extensively tested with FRR and those changes will
be upstreamed if/after it gets accepted.

When we modify or create a new fdb entry sometimes we want to avoid
refreshing its activity in order to track it properly. One example is
when a mac is received from EVPN multi-homing peer by FRR, which doesn't
want to change local activity accounting. It makes it static and sets a
flag to track its activity.

This patch adds the ability to notify about activity of any entries
(static, permanent or ext_learn). EVPN multihoming peers need it to
properly and efficiently handle mac sync (peer active/locally active).
We add a new NFEA_ACTIVITY_NOTIFY attribute which is used to dump the
current activity state and to control if static entries should be monitored
at all. We use 2 bits - one to activate fdb entry tracking (disabled by
default) and the second to denote that an entry is inactive. We need
the second bit in order to avoid multiple notifications of inactivity.
Obviously this makes no difference for dynamic entries since at the time
of inactivity they get deleted, while the tracked non-dynamic entries get
the inactive bit set and get a notification.

net: phy: mscc: PHC and timestamping support
This series aims at adding support for PHC and timestamping operations
in the MSCC PHY driver, for the VSC858x and VSC8575. Those PHYs are
capable of timestamping in 1-step and 2-step for both L2 and L4 traffic.
As of this series, only IPv4 support was implemented when using L4 mode.
This is because of an hardware limitation which prevents us for
supporting both IPv4 and IPv6 at the same time. Implementing support for
IPv6 should be quite easy (I do have the modifications needed for the
hardware configuration) but I did not see a way to retrieve this
information in hwtstamp(). What would you suggest?
Those PHYs are distributed in hardware packages containing multiple
times the PHY. The VSC8584 for example is composed of 4 PHYs. With
hardware packages, parts of the logic is usually common and one of the
PHY has to be used for some parts of the initialization. Following this
logic, the 1588 blocks of those PHYs are shared between two PHYs and
accessing the registers has to be done using the "base" PHY of the
group. This is handled thanks to helpers in the PTP code (and locks).
We also need the MDIO bus lock while performing a single read or write
to the 1588 registers as the read/write are composed of multiple MDIO
transactions (and we don't want other threads updating the page).
To get and set the PHC time, a GPIO has to be used and changes are only
retrieved or committed when on a rising edge. The same GPIO is shared by
all PHYs, so the granularity of the lock protecting it has to be
different from the ones protecting the 1588 registers (the VSC8584 PHY
has 2 1588 blocks, and a single load/save pin).
Patch 1 extends the recently added helpers to share information between
PHYs of the same hardware package; to allow having part of the probe to
be shared (in addition to the already supported init part). This will be
used when adding support for PHC/TS to initialize locks.
Patches 2 and 3 are mostly cosmetic.
Patch 4 takes into account the 1588 block in the MACsec initialization,
to allow having both the MACsec and 1588 blocks initialized on a running
system.
Patches 5 and 6 add support for PHC and timestamping operations in the
MSCC driver. An initialization of the 1588 block (plus all the registers
definition; and helpers) is added first; and then comes a patch to
implement the PHC and timestamping API.
Patches 7 and 8 add the required hardware description for device trees,
to be able to use the load/save GPIO pin on the PCB120 board.
To use this on a PCB120 board, two other series are needed and have
already been sent upstream (one is merged). There are no dependency
between all those series.
Since v3:
- Fixed a SKB leak.
- Removed ts_lock from the init, as TS and PHC operations aren't
registered at this time.
- Refectored the ts_base_addr/phy intialization.
- Cleaned up the ingr/egr latencies definitons.
- Fixed a comment about locking and the shared GPIO.
- A few cosmetic fixes.
Since v2:
- Removed explicit inlines from .c files.
- Fixed three warnings.
Since v1:
- Removed checks in rxtstamp/txtstamp as skb cannot be NULL here.
- Reworked get_ptp_header_rx/get_ptp_header.
- Reworked the locking logic between the PHC and timestamping
operations.
- Fixed a compilation issue on x86 reported by Jakub.

Run rxtimestamp as part of TEST_PROGS. Analogous to other tests, add
new rxtimestamp.sh wrapper script, so that the test runs isolated
from background traffic in a private network namespace.
Also ignore failures of test case #6 by default. This case verifies
that a receive timestamp is not reported if timestamp reporting is
enabled for a socket, but generation is disabled. Receive timestamp
generation has to be enabled globally, as no associated socket is
known yet. A background process that enables rx timestamp generation
therefore causes a false positive. Ntpd is one example that does.
Add a "--strict" option to cause failure in the event that any test
case fails, including test #6. This is useful for environments that
are known to not have such background processes.
