Cross time-stamping mechanism used in certain instance of Intel mGbE
may run at different clock frequency in comparison to the clock
frequency used by processor, so we introduce cross T/S frequency
adjustment to ensure TSC calculation is correct when processor got the
cross time-stamps.

The function lan87xx_config_aneg_ext was introduced to configure
LAN95xxA but as well writes to undocumented register of LAN87xx.
This fix prevents that access.
The function lan87xx_config_aneg_ext gets more suitable for the new
behavior name.

D_CAN controller supports 16, 32, 64 or 128 message objects, comparing
to 32 on C_CAN. AM335x/AM437x Sitara processors and DRA7 SOC all
instantiate a D_CAN controller with 64 message objects, as described
in the "DCAN features" subsection of the CAN chapter of their
technical reference manuals.
The driver policy has been kept unchanged, and as in the previous
version, the first half of the message objects is used for reception
and the second for transmission.
The I/O load is increased only in the case of 64 message objects,
keeping it unchanged in the case of 32. Two 32-bit read accesses are
in fact required, which however remained at 16-bit for configurations
with 32 message objects.

As pointed by commit c0a9f4d396c9 ("can: c_can: Reduce register
access") the "driver casts the 16 message objects in stone, which is
completely braindead as contemporary hardware has up to 128 message
objects".
The patch prepares the module to extend the number of message objects
beyond the 32 currently managed. This was achieved by transforming the
constants used to manage RX/TX messages into variables without
changing the driver policy.

In the patches:
| 1f652bb6bae7 can: mcp25xxfd: rx-path: reduce number of SPI core requests to set UINC bit
| 68c0c1c7f966 can: mcp251xfd: tef-path: reduce number of SPI core requests to set UINC bit
the setting of the UINC bit in the TEF and RX FIFO was batched into a
single SPI message consisting of several transfers. All transfers but
the last need to have the cs_change set to 1.
In the original patches the array of prepared transfers is send from
the beginning with the length depending on the number of read TEF/RX
objects. The cs_change of the last transfer is temporarily set to
0 during send.
This patch removes the modification of cs_change by preparing the last
transfer with cs_change to 0 and all other to 1. When sending the SPI
message the driver now starts with an offset into the array, so that
it always ends on the last entry in the array, which has the cs_change
set to 0.

For easier debugging this patch adds dev coredump support to the
driver. A dev coredump is generated in case the chip fails to start or
an error in the interrupt handler is detected.
The dev coredump consists of all chip registers and chip memory, as
well as the driver's internal state of the TEF-, RX- and TX-FIFOs, it
can be analyzed with the mcp251xfd-dump tool of the can-utils:

softirq context
For peripheral devices, m_can sent skbs directly from a threaded irq
instead of from a softirq context, breaking the tcan4x5x peripheral
driver completely. This patch transitions the driver to use the
rx-offload helper for peripherals, ensuring the skbs are sent from the
correct context, with h/w timestamping to ensure correct ordering.

This is a prerequisite for transitioning the m_can driver to rx-offload,
which works best with TX and RX timestamps.
The timestamps provided by M_CAN are 16-bit, timed according to the
nominal bit timing, and may be prescaled by a multiplier up to 16. We
choose the highest prescalar so that the timestamp wraps every 2^20 bit
times, or 209 ms at a bus speed of 5 Mbit/s. Timestamps will have a
precision of 16 bit times.

Add three macro to simplify the readability of big bit timing numbers:
- CAN_KBPS: kilobits per second (one thousand)
- CAN_MBPS: megabits per second (one million)
- CAN_MHZ: megahertz per second (one million)
Example:
u32 bitrate_max = 8 * CAN_MBPS;
struct can_clock clock = {.freq = 80 * CAN_MHZ};
instead of:
u32 bitrate_max = 8000000;
struct can_clock clock = {.freq = 80000000};
Apply the new macro to driver/net/can/dev/bittiming.c.

The logic for the tdco calculation is to just reuse the normal sample
point: tdco = sp. Because the sample point is expressed in tenth of
percent and the tdco is expressed in time quanta, a conversion is
needed.
At the end,
ssp = tdcv + tdco
= tdcv + sp.
Another popular method is to set tdco to the middle of the bit:
tdc->tdco = can_bit_time(dbt) / 2
During benchmark tests, we could not find a clear advantages for one
of the two methods.
The tdco calculation is triggered each time the data_bittiming is
changed so that users relying on automated calculation can use the
netlink interface the exact same way without need of new parameters.
For example, a command such as:
ip link set canX type can bitrate 500000 dbitrate 4000000 fd on
would trigger the calculation.
The user using CONFIG_CAN_CALC_BITTIMING who does not want automated
calculation needs to manually set tdco to zero.
For example with:
ip link set canX type can tdco 0 bitrate 500000 dbitrate 4000000 fd on
(if the tdco parameter is provided in a previous command, it will be
overwritten).
If tdcv is set to zero (default), it is automatically calculated by
the transiver for each frame. As such, there is no code in the kernel
to calculate it.
tdcf has no automated calculation functions because we could not
figure out a formula for this parameter.

In order to implement byte queue limits (bql) in CAN drivers, the
length of the CAN frame needs to be passed into the networking stack
even if the transmission failed for some reason.
To avoid to calculate this length twice, extend can_free_echo_skb() to
return that value. Convert all users of this function, too.

So far the creation of the TX echo skb was optional and can be
controlled by the local sender of a CAN frame.
It turns out that the TX echo CAN skb can be piggybacked to carry
information in the driver from the TX- to the TX-complete handler.
Several drivers already use the return value of
can_get_echo_skb() (which is the length of the data field in the CAN
frame) for their number of transferred bytes statistics. The
statistics are not working if CAN echo skbs are disabled.
Another use case is to calculate and set the CAN frame length on the
wire, which is needed for BQL support in both the TX and TX-completion
handler.
For now in can_put_echo_skb(), which is called from the TX handler,
the skb carrying the CAN frame is discarded if no TX echo is
requested, leading to the above illustrated problems.
This patch changes the can_put_echo_skb() function, so that the echo
skb is always generated. If the sender requests no echo, the echo skb
is consumed in __can_get_echo_skb() without being passed into the RX
handler of the networking stack, but the CAN data length and CAN frame
length information is properly returned.

Add PTP-TIR and initiate its RQT to allow PTP-RQ to integrate into the
safe-reopen flow on configuration change. Add rx_ptp_support flag on a
profile and turn it on for ETH driver. With this flag set, create a
redirect-RQT for PTP-RQ.

Like PTP-TX, once the PTP-RX is opened, corresponding statistics appear.
Add indication that PTP-RX was ever opened: rx_ptp_opened. If any of the
PTP RX or TX were opened, display the PTP channel's statistics.

Enhance PTP channel to allow PTP without disabling CQE compression. Add
RQ, TIR and PTP_RX_STATE to PTP channel. When this bit is set, PTP
channel manages its RQ, and PTP traffic is directed to the PTP-RQ which
is not affected by compression.
