When the uplink representors are put into lag, set all the
representors (VFs and uplinks) of the same NIC to return the same
switchdev id.
Currently, the route lookup code on the encapsulation offload path
assumes that same switchdev id for the source and dest devices means
that the dest is also mlx5 HW netdev. This doesn't hold anymore when we
align the switchdev Id of the uplinks to be same, which in turn causes
the bond/team to return that id to the caller. As such, enhance the
relevant check to take into account the uplink lag case.

Assign a counter dev attribute according to device capability and use
it for management of counters related to offloaded eswitch TC flows.
With upcoming support for uplink LAG, we have two HW rules per one
logical SW (TC) rule. Although the HW supports attaching one counter
to multiple rules, we are allocating counter per HW rule.
We need this separation for two reasons:
1. "flow eswitch" counter affinity HW require the counter to be
allocated on the device where the eswitch rule is set.
2. for some use-cases (multi-path routing) each HW flow relates to
different neighbour, hence our neigh update logic must have a per-rule
HW accountant in order to provide the proper feedback to the kernel.

Under uplink LAG or multipath schemes, traffic that matches one flow
might arrive on both uplink ports and transmitted through both
as part of supporting aggregation and high-availability.
To cope with the fact that the SW model might use logical SW port
(e.g uplink team or bond) but we have two HW ports with e-switch on
each, there are cases where in order to offload a SW TC rule we
need to duplicate it to two HW flows.
Since each HW rule has its own counter we also aggregate the counter
of both rules when a flow stats query is executed from user-space.
Introduce the changes for the different elements (add/delete/stats),
currently nothing is duplicated.

In the sriov offloads mode, packets that are not matched by any
other rule are sent towards the e-switch vport manager for further
processing.
Under upcoming patches (e.g for uplink LAG), packets sent from VF
vports belonging to esw0 (e-switch related to PF0) might end up in
esw1 (e-switch related to PF1) due to muxing logic applied by the
FW.
In such a case we still want the missed packet to be sent to the
"base" esw manager vport in order to present the control plane a
consistent view of the source (VF reresentor) port.

This dictates the device affinity for eswitch flow counters, set by the FW
according to the HW device capabilities.
Under "source eswitch" affinity, the counter should be allocated on the
device related to the source vport in the match. This covers both non
merged e-switch mode as well as old FW that does not advertise this cap.
Under "flow eswitch" affinity, the counter should be allocated on the
device where the eswitch rule is set.

When in switchdev mode and the add function is called by the core
level driver, make sure we only register the callbacks, but don't
create the mlx5 IB device or initialize anything. With this change
all the IB devices in switchdev mode are created only once the load
callback is invoked by the e-switch core sub-module. This follows
the design paradigm under which the all the Eth representors must
be loaded before any of IB reprs is loaded.

Petr Machata says:
====================
Introduce NETDEV_PRE_CHANGEADDR
Spectrum devices have a limitation that all router interfaces need to
have the same address prefix. In Spectrum-1, the requirement is for the
initial 38 bits of all RIFs to be the same, in Spectrum-2 the limit is
36 bits. Currently violations of this requirement are not diagnosed. At
the same time, if the condition is not upheld, the mismatched MAC
address ends up overwriting the common prefix, and all RIF MAC addresses
silently change to the new prefix.
It is therefore desirable to be able at least to diagnose the issue, and
better to reject attempts to change MAC addresses in ways that is
incompatible with the device.
Currently MAC address changes are notified through emission of
NETDEV_CHANGEADDR, which is done after the change. Extending this
message to allow vetoing is certainly possible, but several other
notification types have instead adopted a simple two-stage approach:
first a "pre" notification is sent to make sure all interested parties
are OK with the change that's about to be done. Then the change is done,
and afterwards a "post" notification is sent.
This dual approach is easier to use: when the change is vetoed, nothing
has changed yet, and it's therefore unnecessary to roll anything back.
Therefore this patchset introduces it for NETDEV_CHANGEADDR as well.
One prominent path to emitting NETDEV_CHANGEADDR is through
dev_set_mac_address(). Therefore in patch #1, give this function an
extack argument, so that a textual reason for rejection (or a warning)
can be communicated back to the user.
In patch #2, add the new notification type. In patch #3, have dev.c emit
the notification for instances of dev_addr change, or addition of an
address to dev_addrs list.
In patches #4 and #5, extend the bridge driver to handle and emit the
new notifier.
In patch #6, change IPVLAN to emit the new notifier.
Likewise for bonding driver in patches #7 and #8. Note that the team
driver doesn't need this treatment, as it goes through
dev_set_mac_address().
In patches #9, #10 and #11 adapt mlxsw to veto MAC addresses on router
interfaces, if they violate the requirement that all RIF MAC addresses
have the same prefix.
Finally in patches #12 and #13, add a test for vetoing of a direct
change of a port device MAC, and indirect change of a bridge MAC.

When a port is attached to a bridge, the address of the bridge in
question may change as well. Even if it would not change at this
point (because the current bridge address is lower), it might end up
changing later as a result of detach of another port, which can't be

Pass extack to SWITCHDEV_PORT_OBJ_ADD
Drivers may need to do validation as a result of port object addition.
An example is mlxsw, which needs to check the configuration of a VXLAN
device attached to an offloaded bridge. Without a mapped VLAN, the
invalidity of the device is not important, but as soon as a pvid,
untagged VLAN is configured for the device, it has to be validated and
offloaded. Should the validation fail, there's currently no way to
communicate details of the failure to the user, beyond an error number.
Because currently, extack is not available at all in that area of code,
this patch starts down at the RTNL level and progresses up towards the
driver(s).
In patch #1, ndo_bridge_setlink is updated to include extack, and
callbacks of all clients are updated as well (ignoring the argument).
In patch #2, the bridge driver is updated to propagate the extack
through to the switchdev border, br_switchdev_port_vlan_add().
Patches #3, #4 and #5 then gradually extend switchdev to pass the extack
argument through to the switchdev blocking notifier chain.
Patches #6 and #7 then update mlxsw to pass the extack argument from
VXLAN events resp. port events on to mlxsw_sp_bridge_8021q_vxlan_join().
Finally in patches #8 and #9, the code paths from the previous two
patches are verified to yield an error message.
v2:
- Patch #1:
- In ndo_bridge_setlink(), keep the whole extack declaration on the
same line.

2. add comments in driver to avoid confusion.
2. rewrite set_delay function.
3. modify binding document for properties: tx-delay-ps/rx-delay-ps/pericfg etc.

mlxsw: Add Spectrum-2 multicast routing support
Nir says:
In Spectrum the firmware provided an abstraction for multicast routing
on top of the policy engine. In Spectrum-2 this is no longer the case
and the driver must interact directly with the policy engine in order to
program multicast routes. Every route is written as an ACL rule, its
priority set according to route type (*,G) or (S,G) and its action is an
appropriate multicast routing action. Multicast routes are written to a
specific ACL group which is bound to the appropriate IP protocol
IPv4/IPv6.
Patch #1 adds PEMRBT register needed to declare which ACL group is
dedicated for each IP protocol multicast routing function.
Patch #2 Changes initialization order and puts ACL before router as
multicast router now uses ACL module.
Patch #3 adds Spectrum-2 ACL keys needed for multicast route matching.
Patch #4 adds another ACL profile - in addition to existing flower
profile - which allows the multicast routing module to program rules
directly into the ACL block.
Patch #5 adds the ability to update ACL rules' action, since multicast
routes actions may be updated after being configured.
Patch #6 separates rule creation operation and rule action creation
operation as in multicast router the action is created before the route
is inserted.
Patch #7 sharpens priority handling in Spectrum-2, to ensure incorrect
values are not set to rule's priority.
Patch #8 adds the implementation of multicast routing for IPv4 and IPv6
over existing ACL rule programming
Finally, patch #9 adds a test for IPv4/IPv6 multicast routing.

Introduce basic testing for both IPv4 and IPv6 multicast. The test creates
an (S,G) type route, sends traffic and verifies traffic arrives when the
route is present and then verifies traffic does not arrive after deleting
the route.
This test requires smcroute - https://github.com/troglobit/smcroute which
is a tool that allows creation of static multicast routes.

Add implementation of Spectrum-2 multicast routes for both IPv4 and IPv6 by
using ACL module explicitly.
In Spectrum-2, multicast routes are set as ACL rules, so initialization
takes care of creating dedicated ACL groups and binding them to the
appropriate multicast routing protocol IPv4/IPv6, and afterwards routes
configuration translates to setting explicit ACL rules.

In Spectrum-2, higher priority value wins and priority valid values are in
the range of {1,cap_kvd_size-1}. mlxsw_sp_acl_tcam_priority_get converts
from lower-bound priorities alike tc flower to Spectrum-2 HW range. Up
until now tc flower did not provide priority 0 or reached the maximal
value, however multicast routing does provide priority 0.
Therefore, Change mlxsw_sp_acl_tcam_priority_get to verify priority is in
the correct range. Make sure priority is never set to zero and never
exceeds the maximal allowed value.

Up until now, when ACL rule was created its action was created with it.
It suits well for tc flower where ACL rule always needs an action, however
it does not suit multicast router, where the action is created prior to
setting a route, which in Spectrum-2 is actually an ACL rule.
Add support for rule creation without action creation. Do it by adding
afa_block argument to mlxsw_sp_acl_rule_create, which if NULL then an
action would be created, also add an indication within struct
mlxsw_sp_acl_rule_info that tells if the action should be destroyed when
the rule is destroyed.
