One small fix embedded is the reset of one_packet at every iteration.
This allows bundling of some control chunks in case they were preceeded by
another control chunk that cannot be bundled.

Other than this, it has the same behavior.

Currently, when the rule is not to be exclusively executed by the
hardware, extack is not passed along and offloading failures don't
get logged. The idea was that hardware failures are okay because the
rule will get executed in software then and this way it doesn't confuse
unware users.

But this is not helpful in case one needs to understand why a certain
rule failed to get offloaded. Considering it may have been a temporary
failure, like resources exceeded or so, reproducing it later and knowing
that it is triggering the same reason may be challenging.

The ultimate goal is to improve Open vSwitch debuggability when using
flower offloading.

This patch adds a new flag to enable verbose logging. With the flag set,
extack will be passed to the driver, which will be able to log the
error. As the operation itself probably won't fail (not because of this,
at least), current iproute will already log it as a Warning.

The flag is generic, so it can be reused later. No need to restrict it
just for HW offloading. The command line will follow the syntax that
tc-ebpf already uses, tc ... [ verbose ] ... , and extend its meaning.

For example:
# ./tc qdisc add dev p7p1 ingress
# ./tc filter add dev p7p1 parent ffff: protocol ip prio 1 \
	flower verbose \
	src_mac ed:13:db:00:00:00 dst_mac 01:80:c2:00:00:d0 \
	src_ip 56.0.0.0 dst_ip 55.0.0.0 action drop
Warning: TC offload is disabled on net device.
# echo $?

net: stmmac: dwmac-sun8i: Support R40

This is a resend of the patches for net-next split out from my R40
Ethernet support v2 series, as requested by David Miller. The arm-soc
bits will follow, once I rework the A64 system controller compatible.

Patches 1, 2, and 3 clean up the dwmac-sun8i binding.

Patch 4 adds device tree binding for Allwinner R40's Ethernet
controller.

Patch 5 converts regmap access of the syscon region in the dwmac-sun8i
driver to regmap_field, in anticipation of different field widths on
the R40.

Patch 6 introduces custom plumbing in the dwmac-sun8i driver to fetch
a regmap from another device, by looking up said device via a phandle,
then getting the regmap associated with that device.

Patch 7 adds support for different or absent TX/RX delay chain ranges
to the dwmac-sun8i driver.

Patch 8 adds support for the R40's ethernet controller.

Excerpt from original cover letter:

Changes since v1:

  - Default to fetching regmap from device pointed to by syscon phandle,
    and falling back to syscon API if that fails.

  - Dropped .syscon_from_dev field in device data as a result of the
    previous change.

  - Added a large comment block explaining the first change.

  - Simplified description of syscon property in sun8i-dwmac binding.

  - Regmap now only exposes the EMAC/GMAC register, but retains the
    offset within its address space.

  - Added patches for A64, which reuse the same sun8i-dwmac changes.

This series adds support for the DWMAC based Ethernet controller found
on the Allwinner R40 SoC. The controller is either a DWMAC clone or
DWMAC core with its registers rearranged. This is already supported by
the dwmac-sun8i driver. The glue layer control registers, unlike other
sun8i family SoCs, is not in the system controller region, but in the
clock control unit, like with the older A20 and A31 SoCs.

While we reuse the bindings for dwmac-sun8i using a syscon phandle
reference, we need some custom plumbing for the clock driver to export
a regmap that only allows access to the GMAC register to the dwmac-sun8i
driver. An alternative would be to allow drivers to register custom
syscon devices with their own regmap and locking.

On the Allwinner R40 SoC, the "GMAC clock" register is in the CCU
address space. Using a standard syscon to access it provides no
coordination with the CCU driver for register access. Neither does
it prevent this and other drivers from accessing other, maybe critical,
clock control registers. On other SoCs, the register is in the "system
control" address space, which might also contain controls for mapping
SRAM to devices or the CPU. This hardware has the same issues.

Instead, for these types of setups, we let the device containing the
control register create a regmap tied to it. We can then get the device
from the existing syscon phandle, and retrieve the regmap with
dev_get_regmap().

On the Allwinner R40, the "GMAC clock" register is located in the CCU
block, at a different register address than the other SoCs that have
it in the "system control" block.

This patch converts the use of regmap to regmap_field for mapping and
accessing the syscon register, so we can have the register address in
the variants data, and not in the actual register manipulation code.

This patch only converts regmap_read() and regmap_write() calls to
regmap_field_read() and regmap_field_write() calls. There are some
places where it might make sense to switch to regmap_field_update_bits(),
but this is not done here to keep the patch simple.

The syscon property is used to point to the device that holds the glue

We do not need to explicitly list what compatible strings are needed, as
this information is readily available in the user manuals. Also the
"syscon" device type is more of an implementation detail. There are many
ways to access a register not in a device's address range, the syscon

kernel: add support to collect hardware logs in crash recovery kernel

On production servers running variety of workloads over time, kernel
panic can happen sporadically after days or even months. It is
important to collect as much debug logs as possible to root cause
and fix the problem, that may not be easy to reproduce. Snapshot of
underlying hardware/firmware state (like register dump, firmware
logs, adapter memory, etc.), at the time of kernel panic will be very
helpful while debugging the culprit device driver.

This series of patches add new generic framework that enable device
drivers to collect device specific snapshot of the hardware/firmware
state of the underlying device in the crash recovery kernel. In crash
recovery kernel, the collected logs are added as elf notes to
/proc/vmcore, which is copied by user space scripts for post-analysis.

The sequence of actions done by device drivers to append their device
specific hardware/firmware logs to /proc/vmcore are as follows:

1. During probe (before hardware is initialized), device drivers
register to the vmcore module (via vmcore_add_device_dump()), with
callback function, along with buffer size and log name needed for
firmware/hardware log collection.

2. vmcore module allocates the buffer with requested size. It adds
an elf note and invokes the device driver's registered callback
function.

3. Device driver collects all hardware/firmware logs into the buffer
and returns control back to vmcore module.

The device specific hardware/firmware logs can be seen as elf notes
with note type 0x700, as shown below:

Displaying notes found at file offset 0x00001000 with length 0x040032c0:
  Owner                 Data size	Description

  VMCOREINFO           0x00000785	Unknown note type: (0x00000000)

Patch 1 adds API to vmcore module to allow drivers to register callback
to collect the device specific hardware/firmware logs.  The logs will
be added to /proc/vmcore as elf notes.

Patch 2 updates read and mmap logic to append device specific hardware/
firmware logs as elf notes.

Patch 3 shows a cxgb4 driver example using the API to collect
hardware/firmware logs in crash recovery kernel, before hardware is
initialized.

Rahul

Update read and mmap logic to append device dumps as additional notes
before the other elf notes. We add device dumps before other elf notes
because the other elf notes may not fill the elf notes buffer
completely and we will end up with zero-filled data between the elf
notes and the device dumps. Tools will then try to decode this
zero-filled data as valid notes and we don't want that. Hence, adding
device dumps before the other elf notes ensure that zero-filled data
can be avoided. This also ensures that the device dumps and the
other elf notes can be properly mmaped at page aligned address.

The pfc related priority stats are already handled separately as these
stats are actually arrays of length I40E_MAX_USER_PRIORITY. Thus,
including them within i40e_gstrings_stats will just duplicate data.

Worse, the sizeof will be incorrect, as it will be the total size of the
stat arrays, which in this case is 8 * sizeof(u64), so we will only copy
the stat contents as if they were a u32.

Since we already correctly handle these stats else where, remove them
from the i40e_gstrings_stats.

Use a separate function to calculate the number of stats for
a particular device. This helps reduce the clutter in
i40e_get_sset_count().

Clean up existing instances of unnecessary parentheses in if
statement and change order of conditionals to make it easier to read

The opening /* should be followed by a single space and the closing */
should be preceded with a single space.

When CONFIG_PROC_FS isn't set, variable ipconfig_dir isn't used.
net/ipv4/ipconfig.c:167:31: warning: ‘ipconfig_dir’ defined but not used [-Wunused-variable]
 static struct proc_dir_entry *ipconfig_dir;
                               ^~~~~~~~~~~~
Move the declaration of ipconfig_dir inside the CONFIG_PROC_FS ifdef to
fix the warning.

The bpf syscall and selftests conflicts were trivial
overlapping changes.

The r8169 change involved moving the added mdelay from 'net' into a
different function.

A TLS close bug fix overlapped with the splitting of the TLS state
into separate TX and RX parts.  I just expanded the tests in the bug
fix from "ctx->conf == X" into "ctx->tx_conf == X && ctx->rx_conf
== X".
