Currently all RX frames are timestamped which results in a performance
penalty when timestamping is not needed. The default is now being
changed to not timestamp any Rx frames (HWTSTAMP_FILTER_NONE), but
support has been added to allow changing the desired RX timestamping
mode (HWTSTAMP_FILTER_ALL - which was the previous setting and
HWTSTAMP_FILTER_PTP_V2_EVENT are now supported) using
SIOCSHWTSTAMP. All settings were tested using the hwstamp_ctl application.
It is also noted that ptp4l, when started, preconfigures the device to
timestamp using HWTSTAMP_FILTER_PTP_V2_EVENT, so this driver continues
to work properly "out of the box".

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert these drivers from always returning zero in the remove
callback to the void returning variant.

When operating in fixed phy mode and if there is repeated open/close
phy test cases, everytime the fixed phy is registered as a new phy
which leads to overrun after 32 iterations. It is solved by adding
fixed_phy_unregister() in the phy_close path.
In phy_close path, netdev->phydev cannot be used directly in
fixed_phy_unregister() due to two reasons,
- netdev->phydev is set to NULL in phy_disconnect()
- fixed_phy_unregister() can be called only after phy_disconnect()
So saving the netdev->phydev in local variable 'phydev' and
passing it to phy_disconnect().

It is desirable that the new .ndo_hwtstamp_set() API gives more
uniformity, less overhead and future flexibility w.r.t. the PHY
timestamping behavior.
Currently there are some drivers which allow PHY timestamping through
the procedure mentioned in Documentation/networking/timestamping.rst.
They don't do anything locally if phy_has_hwtstamp() is set, except for
lan966x which installs PTP packet traps.
Centralize that behavior in a new dev_set_hwtstamp_phylib() code
function, which calls either phy_mii_ioctl() for the phylib PHY,
or .ndo_hwtstamp_set() of the netdev, based on a single policy
(currently simplistic: phy_has_hwtstamp()).
Any driver converted to .ndo_hwtstamp_set() will automatically opt into
the centralized phylib timestamping policy. Unconverted drivers still
get to choose whether they let the PHY handle timestamping or not.
Netdev drivers with integrated PHY drivers that don't use phylib
presumably don't set dev->phydev, and those will always see
HWTSTAMP_SOURCE_NETDEV requests even when converted. The timestamping
policy will remain 100% up to them.

As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and

Since we already have an "enable" variable in tc_taprio_qopt_offload,

every other command except "replace" and "destroy" - to be future proof.

It was noticing that after a while when unloading/loading the driver and
sending traffic through the switch, it would stop working. It would stop
forwarding any traffic and the only way to get out of this was to do a
power cycle of the board. The root cause seems to be that the switch
core is initialized twice. Apparently initializing twice the switch core
disturbs the pointers in the queue systems in the HW, so after a while
it would stop sending the traffic.
Unfortunetly, it is not possible to use a reset of the switch here,
because the reset line is connected to multiple devices like MDIO,
SGPIO, FAN, etc. So then all the devices will get reseted when the
network driver will be loaded.
So the fix is to check if the core is initialized already and if that is
the case don't initialize it again.

The Microchip ENC28J60 SPI Ethernet driver schedules a work item from
the interrupt handler because accesses to the SPI bus may sleep.
On PREEMPT_RT (which forces interrupt handling into threads) this
old-fashioned approach unnecessarily increases latency because an
interrupt results in first waking the interrupt thread, then scheduling
the work item. So, a double indirection to handle an interrupt.
Avoid by converting the driver to modern threaded interrupt handling.

When the action of an xdp program was XDP_TX, lan966x was creating
a xdp_frame and use this one to send the frame back. But it is also
possible to send back the frame without needing a xdp_frame, because
it is possible to send it back using the page.
And then once the frame is transmitted is possible to use directly
page_pool_recycle_direct as lan966x is using page pools.
This would save some CPU usage on this path, which results in higher
number of transmitted frames. Bellow are the statistics:
Frame size: Improvement:
64 ~8%
256 ~11%
512 ~8%
1000 ~0%
1500 ~0%

From time to time, it was observed that the nanosecond part of the
received timestamp, which is extracted from the IFH, it was actually
bigger than 1 second. So then when actually calculating the full
received timestamp, based on the nanosecond part from IFH and the second
part which is read from HW, it was actually wrong.
The issue seems to be inside the function lan966x_ifh_get, which
extracts information from an IFH(which is an byte array) and returns the
value in a u64. When extracting the timestamp value from the IFH, which
starts at bit 192 and have the size of 32 bits, then if the most
significant bit was set in the timestamp, then this bit was extended
then the return value became 0xffffffff... . And the reason of this is
because constants without any postfix are treated as signed longs and
that is the reason why '1 << 31' becomes 0xffffffff80000000.
This is fixed by adding the postfix 'ULL' to 1.

When a frame is injected from CPU, it is required to create an IFH(Inter
frame header) which sits in front of the frame that is transmitted.
This IFH, contains different fields like destination port, to bypass the
analyzer, priotity, etc. Lan966x it is using packing library to set and
get the fields of this IFH. But this seems to be an expensive
operations.
If this is changed with a simpler implementation, the RX will be
improved with ~5Mbit while on the TX is a much bigger improvement as it
is required to set more fields. Below are the numbers for TX.

Whenever a frame was received to the CPU, the HW is timestamping the
frame. In the IFH(Inter Frame Header) it is found the nanosecond part
of the timestamps the SW is required to read from HW the second part.
But reading the second part it seems to be a expensive operations, so
so change this such to read the second part only when rx filter is
enabled.
Doing this change gives the RX a performance boost of ~70mbit.

Fix deletion of existing DSCP mappings in the APP table.
Adding and deleting DSCP entries are replicated per-port, since the
mapping table is global for all ports in the chip. Whenever a mapping
for a DSCP value already exists, the old mapping is deleted first.
However, it is only deleted for the specified port. Fix this by calling
sparx5_dcb_ieee_delapp() instead of dcb_ieee_delapp() as it ought to be.
Reproduce:
// Map and remap DSCP value 63
$ dcb app add dev eth0 dscp-prio 63:1
$ dcb app add dev eth0 dscp-prio 63:2
$ dcb app show dev eth0 dscp-prio
