a97f8783a9 igb: unbreak I2C bit-banging on i350
The driver tried to use Linux' native software I2C bus master
(i2c-algo-bits) for exporting the I2C interface that talks to the SFP
cage(s) towards userspace. As-is, however, the physical SCL/SDA pins
were not moving at all, staying at logical 1 all the time.

The main culprit was the I2CPARAMS register where igb was not setting
the I2CBB_EN bit. That meant that all the careful signal bit-banging was
actually not being propagated to the chip pads (I verified this with a
scope).

The bit-banging was not correct either, because I2C is supposed to be an
open-collector bus, and the code was driving both lines via a totem
pole. The code was also trying to do operations which did not make any
sense with the i2c-algo-bits, namely manipulating both SDA and SCL from
igb_set_i2c_data (which is only supposed to set SDA). I'm not sure if
that was meant as an optimization, or was just flat out wrong, but given
that the i2c-algo-bits is set up to work with a totally dumb GPIO-ish
implementation underneath, there's no need for this code to be smart.

The open-drain vs. totem-pole is fixed by the usual trick where the
logical zero is implemented via regular output mode and outputting a
logical 0, and the logical high is implemented via the IO pad configured
as an input (thus floating), and letting the mandatory pull-up resistors
do the rest. Anything else is actually wrong on I2C where all devices
are supposed to have open-drain connection to the bus.

The missing I2CBB_EN is set (along with a safe initial value of the
GPIOs) just before registering this software I2C bus.

The chip datasheet mentions HW-implemented I2C transactions (SFP EEPROM
reads and writes) as well, but I'm not touching these for simplicity.

Tested on a LR-Link LRES2203PF-2SFP (which is an almost-miniPCIe form
factor card, a cable, and a module with two SFP cages). There was one
casualty, an old broken SFP we had laying around, which was used to
solder some thin wires as a DIY I2C breakout. Thanks for your service.
With this patch in place, I can `i2cdump -y 3 0x51 c` and read back data
which make sense. Yay.

bb5dbf2cc6 net: marvell: prestera: add firmware v4.0 support
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.

6689d716fd Merge branch 'MCTP-flow-support'
Jeremy Kerr says:

====================
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.

This change adds a new skb extension for MCTP, to represent a

The intention is to use this in a later change to allow i2c controllers

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.

9a575c8c25 bnxt_en: Refactor coredump functions
The coredump functionality will be used by devlink health. Refactor
these functions that get coredump and coredump length. There is no
functional change, but the following checkpatch warnings were
addressed:

  - strscpy is preferred over strlcpy.
  - sscanf results should be checked, with an additional warning.

8cc95ceb70 bnxt_en: improve fw diagnose devlink health messages
Add firmware event counters as well as health state severity. In
the unhealthy state, recommend a remedy and inform the user as to
its impact.

Readability of the devlink tool's output is negatively impacted by
adding these fields to the diagnosis. The single line of text, as
rendered by devlink health diagnose, benefits from more terse
descriptions, which can be substituted without loss of clarity, even
in pretty printed JSON mode.

892a662f04 bnxt_en: add enable_remote_dev_reset devlink parameter
The reported parameter value should not take into account the state
of remote drivers. Firmware will reject remote resets as appropriate,
thus it is not strictly necessary to check HOT_RESET_ALLOWED before
attempting to initiate a reset. But we add the check so that we can
provide more intuitive messages when reset is not permitted.

This firmware setting needs to be restored from all functions after
a firmware reset.

8f6c5e4d14 bnxt_en: implement devlink dev reload fw_activate
Similar to reload driver_reinit, the RTNL lock is held across reload
down and up to prevent interleaving state changes.  But we need to
subsequently release the RTNL lock while waiting for firmware reset
to complete.

Also keep a statistic on fw_activate resets initiated remotely from
other functions.

228ea8c187 bnxt_en: implement devlink dev reload driver_reinit
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.

v2: Don't use devlink_reload_disable() and devlink_reload_enable().
Instead, check that the netdev is not in unregistered state before
proceeding with reload.

====================
Code movement to br_switchdev.c

This is one more refactoring patch set for the Linux bridge, where more
logic that is specific to switchdev is moved into br_switchdev.c, which
is compiled out when CONFIG_NET_SWITCHDEV is disabled.

9776457c78 net: bridge: mdb: move all switchdev logic to br_switchdev.c
The following functions:

br_mdb_complete
br_switchdev_mdb_populate
br_mdb_replay_one
br_mdb_queue_one
br_mdb_replay
br_mdb_switchdev_host_port
br_mdb_switchdev_host
br_switchdev_mdb_notify

are only accessible from code paths where CONFIG_NET_SWITCHDEV is
enabled. So move them to br_switchdev.c, in order for that code to be
compiled out if that config option is disabled.

Note that br_switchdev.c gets build regardless of whether
CONFIG_BRIDGE_IGMP_SNOOPING is enabled or not, whereas br_mdb.c only got
built when CONFIG_BRIDGE_IGMP_SNOOPING was enabled. So to preserve
correct compilation with CONFIG_BRIDGE_IGMP_SNOOPING being disabled, we
must now place an #ifdef around these functions in br_switchdev.c.
The offending bridge data structures that need this are
br->multicast_lock and br->mdb_list, these are also compiled out of
struct net_bridge when CONFIG_BRIDGE_IGMP_SNOOPING is turned off.
