mlx5-updates-2021-10-29

1) Minor trivial refactoring and improvements
2) Check for unsupported parameters fields in SW steering
3) Support TC offload for OVS internal port, from Ariel, see below.

Ariel Levkovich says:

=====================

Support HW offload of TC rules involving OVS internal port
device type as the filter device or the destination
device.

The support is for flows which explicitly use the internal
port as source or destination device as well as indirect offload
for flows performing tunnel set or unset via a tunnel device
and the internal port is the tunnel overlay device.

Since flows with internal port as source port are added
as egress rules while redirecting to internal port is done
as an ingress redirect, the series introduces the necessary
changes in mlx5_core driver to support the new types of flows
and actions.

br_switchdev_mdb_notify() is conditionally compiled only when

from br_mdb.c, which is conditionally compiled only when
CONFIG_BRIDGE_IGMP_SNOOPING=y.

The shim definition of br_switchdev_mdb_notify() is therefore needed for
the case where CONFIG_NET_SWITCHDEV=n, however we mistakenly put it
there for the case where CONFIG_BRIDGE_IGMP_SNOOPING=n. This results in
build failures when CONFIG_BRIDGE_IGMP_SNOOPING=y and
CONFIG_NET_SWITCHDEV=n.

To fix this, put the shim definition right next to
br_switchdev_fdb_notify(), which is properly guarded by NET_SWITCHDEV=n.
Since this is called only from br_mdb.c, we need not take any extra

If the packet arrived from a vport, going via term

Register callbacks for tc blocks of ovs internal port devices.

This allows an indirect offloading rules that apply on

In case a rule is added to a tc block of an internal port,

Therefore, only packets that previously hit a rule that redirects

To support redirect to ingress device, offloading of REDIRECT_INGRESS

value that is mapped for this internal port using the internal

After that the hw rule will redirect the packet to the root table

The new vport metadata value indicates that this packet is now
arriving through an internal port and therefore should be processed
using rules that apply on the same internal port as the filter device.
Therefore, following rules that apply on this internal port will have

Setting the skb packet type field to host is usually
done when performing forwarding to ingress device.

This is required since the receive handling that is used
by the redirect to ingress action checks whether the packet
doesn't belong to this host and drops the packet in such case.

In order to be able to offload action redirect ingress, tc offload
code needs to accept the skbedit ptype action as well.

There's no special handling in HW for such action since it will
be followed by a redirect action and therefore, this code
only allows us to accept such action in the actions list but
not performing anything specific in HW for it.

Adding infrastructure to map ovs internal port device to vport
match metadata to support offload of rules with internal port as
the filter device or as the destination device.

The infrastructure allows adding and removing internal port device
to an eswitch database and getting a unique vport metadata value to
be placed and match on in reg_c0 when offloading rules that are coming
from or going to an internal port.

The new int port metadata can be written to the source port register
in HW to indicate that current source port of the packet is the
internal port and not one of the actual HW vports (uplink or VF).
Using this method, it is possible to offload TC rules with an OVS
internal port as their destination port (overwriting the src vport
register) or as the filter port (matching on the value of the src
vport register and making sure it matches to the internal port's
value).

There is also a need to handle a miss case where the packet's
src port value was changed in HW to an internal port but a following
rule which matches on this new src port value wasn't found in HW.

In such case, the packet will be forwarded to the driver with
metadata which allows driver to restore the info of the internal
port's netdevice. Once this info is restored, the uplink driver
can forward the packet to the relevant netdevice in SW.

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.

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.

A non-GPL module won't get far, so for consistency
we can make all symbols GPL without risking any real
life breakage.

Both !data[IFLA_BAREUDP_PORT] and !data[IFLA_BAREUDP_ETHERTYPE] are
checked.  We should remove the checks of data[IFLA_BAREUDP_PORT] and
data[IFLA_BAREUDP_ETHERTYPE] that follow since they are always true.

Put both statements together in group and balance the space on both
sides of '=' sign.

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.

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
operation to inform of flow destruction.

Includes a fix for a warning with test builds:
