The Kvaser KCAN controller got a feature to send error frames on request.
The packet KVASER_PCIEFD_PACK_TYPE_EFRAME_ACK signals that the requested
error frame was transmitted.
Since this feature is not supported by the driver, drop the handler and add
KVASER_PCIEFD_PACK_TYPE_EFRAME_ACK to the list of unexpected packet types.

Introduce a method to calculate the exact size in bits of a CAN(-FD)
frame with or without dynamic bitstuffing.
These are all the possible combinations taken into account:
- Classical CAN or CAN-FD
- Standard or Extended frame format
- CAN-FD CRC17 or CRC21
- Include or not intermission
Instead of doing several individual macro definitions, declare the
can_frame_bits() function-like macro. To this extent, do a full
refactoring of the length definitions.
In addition add the can_frame_bytes(). This function-like macro
replaces the existing macro:
- CAN_FRAME_OVERHEAD_SFF: can_frame_bytes(false, false, 0)
- CAN_FRAME_OVERHEAD_EFF: can_frame_bytes(false, true, 0)
- CANFD_FRAME_OVERHEAD_SFF: can_frame_bytes(true, false, 0)
- CANFD_FRAME_OVERHEAD_EFF: can_frame_bytes(true, true, 0)
Function-like macros were chosen over inline functions because they
can be used to initialize const struct fields.
The different maximum frame lengths (maximum data length, including
intermission) are as follow:
Frame type bits bytes
-------------------------------------------------------
Classic CAN SFF no bitstuffing 111 14
Classic CAN EFF no bitstuffing 131 17
Classic CAN SFF bitstuffing 135 17
Classic CAN EFF bitstuffing 160 20
CAN-FD SFF no bitstuffing 579 73
CAN-FD EFF no bitstuffing 598 75
CAN-FD SFF bitstuffing 712 89
CAN-FD EFF bitstuffing 736 92
The macro CAN_FRAME_LEN_MAX and CANFD_FRAME_LEN_MAX are kept as an
alias to, respectively, can_frame_bytes(false, true, CAN_MAX_DLEN) and
can_frame_bytes(true, true, CANFD_MAX_DLEN).
In addition to the above:
- Use ISO 11898-1:2015 definitions for the names of the CAN frame
fields.
- Include linux/bits.h for use of BITS_PER_BYTE.
- Include linux/math.h for use of mult_frac() and
DIV_ROUND_UP(). N.B: the use of DIV_ROUND_UP() is not new to this
patch, but the include was previously omitted.
- Add copyright 2023 for myself.

In their RZN1 SoC, Renesas put a CAN controller supposed to act very
similarly to the original Philips sja1000. In practice, while flooding
the bus with another device, we discovered that the controller very
often after an overrun situation would just refuse any new frame, drop
them all and trigger over and over again the overrun interrupt, even
though the buffer would have been totally emptied. The controller acts
like if its internal buffer offsets (where it writes and where the host
reads) where totally screwed-up.
Renesas manual mentions a single action to perform in order to
resynchronize the read and write offsets within the buffer: performing
a soft reset.
Performing a soft reset takes a bit of time and involves small delays,
so better do that in a threaded handler rather than inside the hard IRQ
handler.
Add platform data to recognize the platforms which need this workaround,
and when the faulty situation is diagnosed, stop what is being
performed and request the threaded handler to be executed in order to
perform the reset.

In order to support a flavor of the sja1000 which sometimes freezes, it
will be needed upon certain interrupts to perform a soft reset. The soft
reset operation takes a bit of time, so better not do it within the hard
interrupt handler but rather in a threaded handler. Let's prepare the
possibility for sja1000_err() to request "interrupting" the current flow
and request the threaded handler to be run while keeping the interrupt
line low.
There is no functional change.

ice: allow matching on meta data
Michal Swiatkowski says:
This patchset is intended to improve the usability of the switchdev
slow path. Without matching on a meta data values slow path works
based on VF's MAC addresses. It causes a problem when the VF wants
to use more than one MAC address (e.g. when it is in trusted mode).
Parse all meta data in the same place where protocol type fields are
parsed. Add description for the currently implemented meta data. It is
important to note that depending on DDP not all described meta data can
be available. Using not available meta data leads to error returned by
function which is looking for correct words in profiles read from DDP.
There is also one small improvement, remove of rx field in rule info
structure (patch 2). It is redundant.

couple of helpers to assist with this, using a slightly simpler test
than the original:

significant bits in the ID.
- phydev_id_compare() compares the bound phydev with the specified
PHY ID, using the bound driver's mask.

The use of a source MAC to direct packets from the VF to the corresponding
port representor is only ok if there is only one MAC on a VF. To support
this functionality when the number of MACs on a VF is greater, it is
necessary to match a source VSI instead of a source MAC.
Let's use the new switch API that allows matching on metadata.
If MAC isn't used in match criteria there is no need to handle adding
rule after virtchnl command. Instead add new rule while port representor
is being configured.
Remove rule_added field, checking for sp_rule can be used instead.
Remove also checking for switchdev running in deleting rule as it can be
called from unroll context when running flag isn't set. Checking for
sp_rule covers both context (with and without running flag).
Rules are added in eswitch configuration flow, so there is no need to
have replay function.

Add meta data matching criteria in the same place as protocol matching
criteria. There is no need to add meta data as special words after
parsing all lookups. Trade meta data in the same why as other lookups.
The one difference between meta data lookups and protocol lookups is
that meta data doesn't impact how the packets looks like. Because of that
ignore it when filling testing packet.
Match on tunnel type meta data always if tunnel type is different than
TNL_LAST.

Information about the direction is currently stored in sw_act.flag.
There is no need to duplicate it in another field.
Setting direction flag doesn't mean that there is a match criteria for
direction in rule. It is only a information for HW from where switch id
should be collected (VSI or port). In current implementation of advance
rule handling, without matching for direction meta data, we can always
set one the same flag and everything will work the same.
Ability to match on direction meta data will be added in follow up

VLAN mask was 0xd000, change it to 0xf000. 4 last bits are flags

Provide an unlocked version of sfp_sm_event() which can be used by
sfp_check_state() to avoid having to keep re-taking the lock if
several signals have changed state.

Swap the order of the rtnl and st_mutex locks - st_mutex is now nested
beneath rtnl lock instead of rtnl being beneath st_mutex. This will
allow us to hold st_mutex only while manipulating the module's hardware
or software control state.

As preparation to moving st_mutex inside rtnl_lock, we need to first
move the rtnl lock to cover reading the state.

There are a couple of locations in the code where we modify
sfp->state, and then call sfp_set_state(, sfp->state) to update
the outputs/soft state to control the module. Provide a helper
which takes a mask and new state so that this is encapsulated in
one location.

High XDP load triggers the netdev watchdog:
|NETDEV WATCHDOG: enp3s0 (igc): transmit queue 2 timed out
The reason is the Tx queue transmission start (txq->trans_start) is not updated
in XDP code path. Therefore, add it for all XDP transmission functions.

Add support for DSCP rewrite in lan966x driver. On egress DSCP is
rewritten from either classified DSCP, or frame DSCP. Classified DSCP is
determined by the Analyzer Classifier on ingress, and is mapped from
classified QoS class and DP level. Classification of DSCP is by default
enabled for all ports.
It is required that DSCP is trusted for the egress port *and* rewrite
table is not empty, in order to rewrite DSCP based on classified DSCP,
otherwise DSCP is always rewritten from frame DSCP.
