Add firmware (FW) version 4.0 support for Marvell Prestera
driver.
Major changes have been made to new v4.0 FW ABI to add support
of new features, introduce the stability of the FW ABI and ensure
better forward compatibility for the future driver vesrions.
Current v4.0 FW feature set support does not expect any changes
to ABI, as it was defined and tested through long period of time.
The ABI may be extended in case of new features, but it will not
break the backward compatibility.
ABI major changes done in v4.0:
- L1 ABI, where MAC and PHY API configuration are split.
- ACL has been split to low-level TCAM and Counters ABI
to provide more HW ACL capabilities for future driver
versions.
To support backward support, the addition compatibility layer is
required in the driver which will have two different codebase under
"if FW-VER elif FW-VER else" conditions that will be removed
in the future anyway, So, the idea was to break backward support
and focus on more stable FW instead of supporting old version
with very minimal and limited set of features/capabilities.
Improve FW msg validation:
* Use __le64, __le32, __le16 types in msg to/from FW to
catch endian mismatch by sparse.
* Use BUILD_BUG_ON for structures sent/recv to/from FW.

MCTP flow support
For certain MCTP transport bindings, the binding driver will need to be
aware of request/response pairing. For example, the i2c binding may need
to set multiplexer configuration when expecting a response from a device
behind a mux.
This series implements a mechanism for informing the driver about these
flows, so it can implement transport-specific behaviour when a flow is
in progress (ie, a response is expected, and/or we time-out on that
expectation). We use a skb extension to notify the driver about the
presence of a flow, and a new dev->ops callback to notify about a flow's
destruction.

Now that we have an extension for MCTP data in skbs, populate the flow
when a key has been created for the packet, and add a device driver

This change adds a new skb extension for MCTP, to represent a
request/response flow.
The intention is to use this in a later change to allow i2c controllers
to correctly configure a multiplexer over a flow.
Since we have a cleanup function in the core path (if an extension is
present), we'll need to make CONFIG_MCTP a bool, rather than a tristate.

This series contains updates to ice driver only.
Michal adds support for eswitch drop and redirect filters from and to

uplink. This is accomplished by adding support for indirect TC tunnel

thus it is not strictly necessary to check HOT_RESET_ALLOWED before

The RTNL lock must be held between down and up to prevent interleaving
state changes, especially since external state changes might release
and allocate different driver resource subsets that would otherwise
need to be tracked and carefully handled. If the down function fails,
then devlink will not call the corresponding up function, thus the
lock is released in the down error paths.

====================
mlxsw: Offload root TBF as port shaper
Petr says:
Egress configuration in an mlxsw deployment would generally have an ETS
qdisc at root, with a number of bands and a priority dispatch between them.
Some of those bands could then have a RED and/or TBF qdiscs attached.
When TBF is used like this, mlxsw configures shaper on a subgroup, which is
the pair of traffic classes (UC + BUM) corresponding to the band where TBF
is installed. This way it is possible to limit traffic on several bands
(subgroups) independently by configuring several TBF qdiscs, each on a
different band.
It is however not possible to limit traffic flowing through the port as
such. The ASIC supports this through port shapers (as opposed to the
abovementioned subgroup shapers). An obvious way to express this as a user
would be to configure a root TBF qdisc, and then add the whole ETS
hierarchy as its child.
TBF (and RED) can currently be used as a root qdisc. This usage has always
been accepted as a special case, when only one subgroup is configured, and
that is the subgroup that root TBF and RED configure. However it was never
possible to install ETS under that TBF.
In this patchset, this limitation is relaxed. TBF qdisc in root position is
now always offloaded as a port shaper. Such TBF qdisc does not limit
offload of further children. It is thus possible to configure the usual
priority classification through ETS, with RED and/or TBF on individual
bands, all that below a port-level TBF. For example:
(1) # tc qdisc replace dev swp1 root handle 1: tbf rate 800mbit burst 16kb limit 1M
(2) # tc qdisc replace dev swp1 parent 1:1 handle 11: ets strict 8 priomap 7 6 5 4 3 2 1 0
(3) # tc qdisc replace dev swp1 parent 11:1 handle 111: tbf rate 600mbit burst 16kb limit 1M
(4) # tc qdisc replace dev swp1 parent 11:2 handle 112: tbf rate 600mbit burst 16kb limit 1M
Here, (1) configures a 800-Mbps port shaper, (2) adds an ETS element with 8
strictly-prioritized bands, and (3) and (4) configure two more shapers,
each 600 Mbps, one under 11:1 (band 0, TCs 7 and 15), one under 11:2 (band
1, TCs 6 and 14). This way, traffic on bands 0 and 1 are each independently
capped at 600 Mbps, and at the same time, traffic through the port as a
whole is capped at 800 Mbps.
In patch #1, TBF is permitted as root qdisc, under which the usual qdisc
tree can be installed.
In patch #2, the qdisc offloadability selftest is extended to cover the
root TBF as well.
Patch #3 then tests that the offloaded TBF shapes as expected.

The Spectrum ASIC allows configuration of maximum shaper on all levels of
the scheduling hierarchy: TCs, subgroups, groups and also ports. Currently,
TBF always configures a subgroup. But a user could reasonably express the
intent to configure port shaper by putting TBF to a root position, around
ETS / PRIO. Accept this usage and offload appropriately.

Clang is a little more pedantic than GCC, which does not warn when
falling through to a case that is just break or return. Clang's version
is more in line with the kernel's own stance in deprecated.rst, which
states that all switch/case blocks must end in either break,
fallthrough, continue, goto, or return. Add the missing break to silence

Some devices have support for loading the PHY FW and in some cases this
can fail. When this fails, the FW will set the corresponding bit in the
link info structure. Also, the FW will send a link event if the correct
link event mask bit is set. Add support for printing an error message
when the PHY FW load fails during any link configuration flow and the
link event flow.
Since ice_check_module_power() is already doing something very similar
add a new function ice_check_link_cfg_err() so any failures reported in
the link info's link_cfg_err member can be printed in this one function.
Also, add the new ICE_FLAG_PHY_FW_LOAD_FAILED bit to the PF's flags so
we don't constantly print this error message during link polling if the
value never changed.

This change adds support for changing MTU on port representor in
switchdev mode, by setting the min/max MTU values on port representor
netdev. Before it was possible to change the MTU only in a limited,
default range (68-1500).
