is_post_ct_flow() function will process only ct_state ESTABLISHED,
then offload_pre_check() function will check FLOW_DISSECTOR_KEY_CT flag.
When config tc filter match ct_state(0/0x3f), dissector->used_keys
with FLOW_DISSECTOR_KEY_CT bit, function offload_pre_check() will
return false, so not offload. This is a special case that can be handled
safely.
Therefore, modify to let initial packet which won't go through conntrack
can be offloaded, as long as the cared ct fields are all zero.

Introduce a simple helper function to replace a common pattern.
When accessing the GRO header, we fetch the pointer from frag0,
then test its validity and fetch it from the skb when necessary.
This leads to the pattern
skb_gro_header_fast -> skb_gro_header_hard -> skb_gro_header_slow
recurring many times throughout GRO code.
This patch replaces these patterns with a single inlined function
call, improving code readability.

mlx5-updates-2022-08-22
Roi Dayan Says:
===============
Add support for SF tunnel offload
Mlx5 driver only supports VF tunnel offload.
To add support for SF tunnel offload the driver needs to:
1. Add send-to-vport metadata matching rules like done for VFs.
2. Set an indirect table for SF vport, same as VF vport.
info smaller sub functions for better maintainability.
rules from esw init phase to representor load phase.
SFs could be created after esw initialized and thus the send-to-vport
meta rules would not be created for those SFs.
By moving the creation of the rules to representor load phase
we ensure creating the rules also for SFs created later.
===============
Lama Kayal Says:
================
Make flow steering API loosely coupled from mlx5e_priv, in a manner to
introduce more readable and maintainable modules.
Make TC's private, let mlx5e_flow_steering struct be dynamically allocated,
and introduce its API to maintain the code via setters and getters
instead of publicly exposing it.
Introduce flow steering debug macros to provide an elegant finish to the
decoupled flow steering API, where errors related to flow steering shall
be reported via them.
All flow steering related files will drop any coupling to mlx5e_priv,
instead they will get the relevant members as input. Among these,
fs_tt_redirect, fs_tc, and arfs.

Issue found during code review. This bug has no impact as long as the
ks8851_net structure is the first element of the ks8851_net_spi structure.
As long as the offset to the ks8851_net struct is zero, the container_of()
macro is subtracting 0 and therefore no damage done. But if the
ks8851_net_spi struct is ever modified such that the ks8851_net struct
within it is no longer the first element of the struct, then the bug would
manifest itself and cause problems.
struct ks8851_net is contained within ks8851_net_spi.
ks is contained within kss.
kss is the priv_data of the netdev structure.

In TI's J7200 SoC CPSW5G ports, each of the 4 ports can be configured
as a QSGMII main or QSGMII-SUB port. This configuration is performed
by phy-gmii-sel driver on invoking the phy_set_mode_ext() function.
It is necessary for the QSGMII main port to be configured before any of
the QSGMII-SUB interfaces are brought up. Currently, the QSGMII-SUB
interfaces come up before the QSGMII main port is configured.
Fix this by moving the call to phy_set_mode_ext() from
am65_cpsw_nuss_ndo_slave_open() to am65_cpsw_nuss_init_slave_ports(),
thereby ensuring that the QSGMII main port is configured before any of
the QSGMII-SUB ports are brought up.

The purpose of system event handler is to handle system interrupts.
Such interrupts are raised to CPU from system programmable logic
devices, upon specific system wide changes, like line card activation
and deactivation.
The purpose is to create an alternative to trap mechanism, which
delivers these events to driver over PCI bus, but not available for
the driver working over I2C bus.
Mechanism is system dependent and applicable only for the systems
equipped with programmable devices with custom logic.

which should be invoked from the registered callbacks when system
interrupt is raised to CPU.

Currently, each line card is initialized using the following steps:
1. Initializing its various fields (e.g., slot index).
2. Creating the corresponding devlink object.
3. Enabling events (i.e., traps) for changes in line card status.
4. Querying and processing line card status.
Unlike traps, the IRQ that notifies the CPU about line card status
changes cannot be enabled / disabled on a per line card basis.
If a handler is registered before the line cards are initialized, the
handler risks accessing uninitialized memory.
On the other hand, if the handler is registered after initialization,
we risk missing events. For example, in step 4, the driver might see
that a line card is in ready state and will tell the device to enable
it. When enablement is done, the line card will be activated and the
IRQ will be triggered. Since a handler was not registered, the event
will be missed.
Solve this by splitting the initialization sequence into two steps
(1-2 and 3-4). In a subsequent patch, the handler will be registered
between both steps.

it leads to the error message:
ftmac100 92000000.mac eth0: error -22 setting MTU to 1504 to include DSA overhead
ftmac100 supports packet length 1518 (MAX_PKT_SIZE constant), so it is
safe to report it in max_mtu.

Currently when we have 2 CPU ports configured for DSA tag_8021q mode and
we put them in a LAG, a PGID dump looks like this:
PGID_SRC[0] = ports 4,
PGID_SRC[1] = ports 4,
PGID_SRC[2] = ports 4,
PGID_SRC[3] = ports 4,
PGID_SRC[4] = ports 0, 1, 2, 3, 4, 5,
PGID_SRC[5] = no ports
(ports 0-3 are user ports, ports 4 and 5 are CPU ports)
There are 2 problems with the configuration above:
- user ports should enable forwarding towards both CPU ports, not just 4,
and the aggregation PGIDs should prune one CPU port or the other from
the destination port mask, based on a hash computed from packet headers.
- CPU ports should not be allowed to forward towards themselves and also
not towards other ports in the same LAG as themselves
The first problem requires fixing up the PGID_SRC of user ports, when
ocelot_port_assigned_dsa_8021q_cpu_mask() is called. We need to say that
when a user port is assigned to a tag_8021q CPU port and that port is in
a LAG, it should forward towards all ports in that LAG.
The second problem requires fixing up the PGID_SRC of port 4, to remove
ports 4 and 5 (in a LAG) from the allowed destinations.
After this change, the PGID source masks look as follows:
PGID_SRC[0] = ports 4, 5,
PGID_SRC[1] = ports 4, 5,
PGID_SRC[2] = ports 4, 5,
PGID_SRC[3] = ports 4, 5,
PGID_SRC[4] = ports 0, 1, 2, 3,
PGID_SRC[5] = no ports
Note that PGID_SRC[5] still looks weird (it should say "0, 1, 2, 3" just
like PGID_SRC[4] does), but I've tested forwarding through this CPU port
and it doesn't seem like anything is affected (it appears that PGID_SRC[4]
is being looked up on forwarding from the CPU, since both ports 4 and 5
have logical port ID 4). The reason why it looks weird is because
we've never called ocelot_port_assign_dsa_8021q_cpu() for any user port
towards port 5 (all user ports are assigned to port 4 which is in a LAG
with 5).
Since things aren't broken, I'm willing to leave it like that for now
and just document the oddity.

This is a partial revert of commit c295f9831f1d ("net: mscc: ocelot:
switch from {,un}set to {,un}assign for tag_8021q CPU ports"), because
as it turns out, this isn't how tag_8021q CPU ports under a LAG are
supposed to work.
Under that scenario, all user ports are "assigned" to the single
tag_8021q CPU port represented by the logical port corresponding to the
bonding interface. So one CPU port in a LAG would have is_dsa_8021q_cpu
set to true (the one whose physical port ID is equal to the logical port
ID), and the other one to false.
In turn, this makes 2 undesirable things happen:
(1) PGID_CPU contains only the first physical CPU port, rather than both
(2) only the first CPU port will be added to the private VLANs used by
ocelot for VLAN-unaware bridging
To make the driver behave in the same way for both bonded CPU ports, we
need to bring back the old concept of setting up a port as a tag_8021q
CPU port, and this is what deals with VLAN membership and PGID_CPU
updating. But we also need the CPU port "assignment" (the user to CPU
port affinity), and this is what updates the PGID_SRC forwarding rules.
All DSA CPU ports are statically configured for tag_8021q mode when the
tagging protocol is changed to ocelot-8021q. User ports are "assigned"
to one CPU port or the other dynamically (this will be handled by a
future change).

The ft_offloads table serves to steer packets, which are from the
eswitch, to the representor associated with the packets' source vport.
Previously, if a packet's source vport or metadata was not associated
with any representor, it was forwarded to the uplink representor. The
representor got packets it shouldn't have as they weren't coming from
the uplink vport.
One such effect of this breakage can be observed if the uplink
representor is attached to a bridge, where such illegal packets will
be broadcast to the remaining ports, flooding the switch with illegal
packets. In the case where IB loopback (e.g, SNAP) is enabled, all
transmitted packets would be looped back, and received by the uplink
representor, and result in an infinite feedback loop.
Therefore, block this hole by adding a default drop rule to the
ft_offloads table, so that all unmatched packets with no associated
representor are dropped.

Follow the advice of the below link and prefer 'strscpy' in this
subsystem. Conversion is 1:1 because the return value is not used.

Modules such as net/dsa/dsa_core.ko might want to iterate through an
array of compatible strings for things such as validation (or rather,
skipping it for some potentially broken drivers).
of_device_is_compatible() is exported, by of_device_compatible_match()
isn't. Export the latter as well, so we don't have to open-code the
iteration.

Port event data must stored to port-state cache regardless of whether
the port uses phylink or not since this data is used by ethtool.

In order to make the underneath API easier to change in the future,
prevent users from dereferencing fwnode from struct device.
Instead, use the specific dev_fwnode() API for that.

Extend MAC support to support also lag interfaces:
1. In case an entry is learned on a port that is part of lag interface,
then notify the upper layers that the entry is learned on the bond
interface
2. If a port leaves the bond and the port is the first port in the lag
group, then it is required to update all MAC entries to change the
destination port.

Offload FDB entries when the original device is a lag interface. Because
all the ports under the lag have the same chip id, which is the chip id
of first port, then add the entries only for the first port.

Extend lan966x_foreign_bridging_check to check also if the upper
interface is a lag device. Don't allow a lan966x port to be part of a
lag if it has foreign interfaces.
