Use TOD_READ_SECONDARY for extts to keep TOD_READ_PRIMARY
for gettime and settime exclusively. Before this change,
TOD_READ_PRIMARY was used for both extts and gettime/settime,
which would result in changing TOD read/write triggers between
operations. Using TOD_READ_SECONDARY would make extts
independent of gettime/settime operation

As per Errata Section 5.1, if EEE is intended to be used, some register
writes must be done once after every hardware reset. This patch now adds
the necessary register writes as listed in the Marvell errata.
Without this fix we experience ethernet problems on some of our boards
equipped with a new version of this ethernet PHY (different supplier).
The fix applies to Marvell Alaska 88E1510/88E1518/88E1512/88E1514

Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.

Oliver Hartkopp contributes 2 patches for the ISOTP protocol. The 1st
adds support for transmission without flow control, the other let's
bind() return an error on incorrect CAN ID formatting.
Geert Uytterhoeven contributes a patch to clean up ctucanfd's Kconfig
file.
Vincent Mailhol's patch for the slcan driver uses the proper function
to check for invalid CAN frames in the xmit callback.
The next patch is by Geert Uytterhoeven and makes the interrupt-names
of the renesas,rcar-canfd dt bindings mandatory.
A patch by my update the ctucanfd dt bindings to include the common
CAN controller bindings.
The last patch is by Akira Yokosawa and fixes a breakage the

The CTU CAN-FD IP core is only useful when used with one of the
corresponding PCI/PCIe or platform (FPGA, SoC) drivers, which depend on
PCI resp. OF.
Hence make the users select the core driver code, instead of letting
then depend on it. Keep the core code config option visible when
compile-testing, to maintain compile-coverage.

Allow the gro_max_size to exceed a value larger than 65536.
There weren't really any external limitations that prevented this other
than the fact that IPv4 only supports a 16 bit length field. Since we have
the option of adding a hop-by-hop header for IPv6 we can allow IPv6 to
exceed this value and for IPv4 and non-TCP flows we can cap things at 65536
via a constant rather than relying on gro_max_size.
[edumazet] limit GRO_MAX_SIZE to (8 * 65535) to avoid overflows.

The code for gso_max_size was added originally to allow for debugging and
workaround of buggy devices that couldn't support TSO with blocks 64K in
size. The original reason for limiting it to 64K was because that was the
existing limits of IPv4 and non-jumbogram IPv6 length fields.
With the addition of Big TCP we can remove this limit and allow the value
to potentially go up to UINT_MAX and instead be limited by the tso_max_size
value.
So in order to support this we need to go through and clean up the
remaining users of the gso_max_size value so that the values will cap at
64K for non-TCPv6 flows. In addition we can clean up the GSO_MAX_SIZE value
so that 64K becomes GSO_LEGACY_MAX_SIZE and UINT_MAX will now be the upper
limit for GSO_MAX_SIZE.
v6: (edumazet) fixed a compile error if CONFIG_IPV6=n,
in a new sk_trim_gso_size() helper.
netif_set_tso_max_size() caps the requested TSO size
with GSO_MAX_SIZE.

RZ/V2M Ethernet is very similar to R-Car Gen3 Ethernet-AVB, though
some small parts are the same as R-Car Gen2.
Other differences to R-Car Gen3 and Gen2 are:
* It has separate data (DI), error (Line 1) and management (Line 2) irqs
rather than one irq for all three.
* Instead of using the High-speed peripheral bus clock for gPTP, it has a
separate gPTP reference clock.

Currently, when the HW has a single interrupt, the driver uses the
GIC, TIC, RIC0 registers to enable and disable interrupts.
When the HW has multiple interrupts, it uses the GIE, GID, TIE, TID,
RIE0, RID0 registers.
However, other devices, e.g. RZ/V2M, have multiple irqs and only have
the GIC, TIC, RIC0 registers.
Therefore, split this into a separate feature.

When ADQ queue groups (TCs) are created via tc mqprio command,
RSS contexts and associated RSS indirection tables are configured
automatically per TC based on the queue ranges specified for
each traffic class.
For ex:
tc qdisc add dev enp175s0f0 root mqprio num_tc 3 map 0 1 2 \
queues 2@0 8@2 4@10 hw 1 mode channel
will create 3 queue groups (TC 0-2) with queue ranges 2, 8 and 4
in 3 queue groups. Each queue group is associated with its
own RSS context and RSS indirection table.
Add support to expose RSS indirection tables for all ADQ queue
groups using ethtool RSS contexts interface.
ethtool -x enp175s0f0 context <tc-num>

If CONFIG_PTP_1588_CLOCK=m and CONFIG_SFC_SIENA=y, the siena driver will fail to link:

Instead of always returning -ENOPKG, decode the firmware error
code further when the HWRM_NVM_INSTALL_UPDATE firmware call fails.
Return a more suitable error code to userspace and log an error
in dmesg.
This is version 2 of the earlier patch that was reverted:
02acd399533e ("bnxt_en: parse result field when NVRAM package install fails")
In this new version, if the call is made through devlink instead of
ethtool, we'll also set the error message in extack.

Add driver support to enable timestamping on all RX packets
that are received by the NIC. This capability can be requested
by the applications using SIOCSHWTSTAMP ioctl with filter type
HWTSTAMP_FILTER_ALL.

For correctness, we need to configure the packet filters for timestamping
during bnxt_open. This way they are always configured after firmware
reset or chip reset. We should not assume that the filters will always
be retained across resets.
This patch modifies the ioctl handler and always configures the PTP
filters in the bnxt_open() path.

This driver was using the TX IRQ handler to perform all TX completion
tasks. Under heavy TX network load, this can cause significant irqs-off
latencies (found to be in the hundreds of microseconds using ftrace).
This can cause other issues, such as overrunning serial UART FIFOs when
using high baud rates with limited UART FIFO sizes.
Switch to using a NAPI poll handler to perform the TX completion work
to get this out of hard IRQ context and avoid the IRQ latency impact.
A separate poll handler is used for TX and RX since they have separate
IRQs on this controller, so that the completion work for each of them
stays on the same CPU as the interrupt.
Testing on a Xilinx MPSoC ZU9EG platform using iperf3 from a Linux PC
through a switch at 1G link speed showed no significant change in TX or
RX throughput, with approximately 941 Mbps before and after. Hard IRQ
time in the TX throughput test was significantly reduced from 12% to
below 1% on the CPU handling TX interrupts, with total hard+soft IRQ CPU
usage dropping from about 56% down to 48%.

The axienet_start_xmit function was updating the tx_bd_tail variable
multiple times, with potential rollbacks on error or invalid
intermediate positions, even though this variable is also used in the
TX completion path. Use READ_ONCE where this variable is read and
WRITE_ONCE where it is written to make this update more atomic, and
move the write before the MMIO write to start the transfer, so it is
protected by that implicit write barrier.

If reading the Interrupt Source Flag register fails with -ENODEV, then
the PHY has been hot-removed and the correct response is to bail out
instead of throwing a WARN splat and attempting to suspend the PHY.
The PHY should be stopped in due course anyway as the kernel
asynchronously tears down the device.

Cache the interrupt mask to avoid re-reading it from the PHY upon every
interrupt.
This will simplify a subsequent commit which detects hot-removal in the
interrupt handler and bails out.
Analyzing and debugging PHY transactions also becomes simpler if such
redundant reads are avoided.
Last not least, interrupt overhead and latency is slightly improved.
