====================
net: lan966x: Add xdp support
Add support for xdp in lan966x driver. Currently only XDP_PASS and
XDP_DROP are supported.
The first 2 patches are just moving things around just to simplify
the code for when the xdp is added.
Patch 3 actually adds the xdp. Currently the only supported actions
are XDP_PASS and XDP_DROP. In the future this will be extended with
XDP_TX and XDP_REDIRECT.
Patch 4 changes to use page pool API, because the handling of the
pages is similar with what already lan966x driver is doing. In this
way is possible to remove some of the code.
All these changes give a small improvement on the RX side:

v2->v3:
- inline lan966x_xdp_port_present
- update max_len of page_pool_params not to be the page size anymore but

Merge branch 'sparx5-TC-key'
Steen Hegelund says:
====================
Extend TC key support for Sparx5 IS2 VCAP
This provides extended tc flower filter key support for the Sparx5 VCAP
functionality.
It builds on top of the initial IS2 VCAP support found in this series:
https://lore.kernel.org/all/
20221020130904.
1215072-1-steen.hegelund@microchip.com/
Overview:
=========
The added flower filter key (dissector) support is this:
- ipv4_addr (sip and dip)
- ipv6_addr (sip and dip)
- control (IPv4 fragments)
- portnum (tcp and udp port numbers)
- basic (L3 and L4 protocol)
- vlan (outer vlan tag info)
- tcp (tcp flags)
- ip (tos field)
The IS2 VCAP supports classified VLAN information which amounts to the
outer VLAN info in case of multiple tags.
Functionality:
==============
Before frames can match IS2 VCAP rules with e.g an IPv4 source address, the
IS2 VCAPs keyset configuration must include keyset that contains a IPv4
source address and this must be configured for the lookup/port/traffic-type
that you want to match on.
The Sparx5 IS2 VCAP has the following traffic types:
- Non-Ethernet frames
- IPv4 Unicast frames
- IPv4 Multicast frames
- IPv6 Unicast frames
- IPv6 Multicast frames
- ARP frames
So to cover IPv4 traffic the two IPv4 categories must be configured with a
keyset that contains IPv4 address information such as the
VCAP_KFS_IP4_TCP_UDP keyset.
The IPv4 and IPv6 traffic types are configured with useful default keysets,
in later series we will use the tc template functionality when we want to
change these defaults.
The flower filter must contain a goto action as its last action and the
chain id must specify the chain id of the next lookup in a VCAP or a
destination outside the VCAP ranges.
To activate the VCAP lookups on a port you must add a TC matchall filter on
the port containing a single goto action that points to the chain id of the
first lookup in the IS2 VCAP.
From then on frames arriving on this port will be matched against the
rules in the IS2 VCAP lookups.
Removing the matchall filter will deactivate the IS2 lookups, but will
leave the VCAP rules in the memory of the VCAP instance, and from then in
frames will no longer be matched against the rules the in IS2 VCAP.
If the matchall rule is added back again the IS2 rules will be active
once more.
Delivery:
=========
This is current plan for delivering the full VCAP feature set of Sparx5:
- TC flower filter statistics and rule order by size and priority
- debugfs support for inspecting rules
- support for TC protocol all
- Sparx5 IS0 VCAP support
- add TC policer and drop action support (depends on the Sparx5 QoS support
upstreamed separately)
- Sparx5 ES0 VCAP support
- TC flower template support
- TC matchall filter support for mirroring and policing ports
- TC flower filter mirror action support
- Sparx5 ES2 VCAP support
Version History:
================
v6 Rebased on the latest next-next master branch.
No other implementation changes.
v5 Add support for a TC matchall filter with a single goto action
which will activate the lookups of the VCAP. Removing this filter
will deactivate the VCAP lookups again.
v4 Add support for TC flower filter goto action and a check of the
actions: check action combinations and the goto chain id.
v3 Add some more details to the explanation in the commit message
about support for MAC_ETYPE keysets and "protocol all" as well as
the classified VLAN information. This is done to help testing the
feature.
No implementation changes in this version.
v2 Split one of the KUNIT tests into 3 tests to fix a kernel robot
build warning.

src_ip 2.0.2.2 action trap action goto chain
81000000
Notes:
- The "protocol all" selection is not supported yet.
- The MAC address rule now needs to use non-ip and non "protocol all". Here
is an example:
tc filter add dev eth12 ingress chain
8000000 prio 10 handle 10 \
protocol 0xbeef flower skip_sw \
dst_mac 0a:0b:0c:0d:0e:0f \
src_mac 2:0:0:0:0:1 \
action trap action goto chain
81000000
- The VLAN rules use classified VLAN information, and to get the
classification information into the frame metadata, the ingress port need
to be added to a bridge with the VID and vlan filtering enabled, like
this (using VID 600 and four ports eth12, eth13, eth14 and eth15):
ip link add name br5 type bridge
ip link set dev br5 up
ip link set eth12 master br5
ip link set eth13 master br5

devlink: Fix warning when unregistering a port
When a devlink port is unregistered, its type is expected to be unset or
otherwise a WARNING is generated [1]. This was supposed to be handled by
cited commit by clearing the type upon 'NETDEV_PRE_UNINIT'.
The assumption was that no other events can be generated for the netdev
after this event, but this proved to be wrong. After the event is
generated, netdev_wait_allrefs_any() will rebroadcast a
'NETDEV_UNREGISTER' until the netdev's reference count drops to 1. This
causes devlink to set the port type back to Ethernet.
Fix by only setting and clearing the port type upon 'NETDEV_POST_INIT'
and 'NETDEV_PRE_UNINIT', respectively. For all other events, preserve
the port type.

If ethtool_ops::get_drvinfo() callback isn't set,
ethtool_get_drvinfo() will fill the ethtool_drvinfo::name and
ethtool_drvinfo::bus_info fields.
However, if the driver provides the callback function, those two
fields are not touched. This means that the driver has to fill these
itself.
Allow the driver to leave those two fields empty and populate them in
such case. This way, the driver can rely on the default values for the

mlxsw: spectrum_switchdev: Add locked bridge port support
Add locked bridge port support by reacting to changes in the
'BR_PORT_LOCKED' flag. When set, enable security checks on the local
port via the previously added SPFSR register.
When security checks are enabled, an incoming packet will trigger an FDB
lookup with the packet's source MAC and the FID it was classified to. If
an FDB entry was not found or was found to be pointing to a different
port, the packet will be dropped. Such packets increment the
"discard_ingress_general" ethtool counter. For added visibility, user
space can trap such packets to the CPU by enabling the "locked_port"
trap. Example:
# devlink trap set pci/0000:06:00.0 trap locked_port action trap
Unlike other configurations done via bridge port flags (e.g., learning,
flooding), security checks are enabled in the device on a per-port basis
and not on a per-{port, VLAN} basis. As such, scenarios where user space
can configure different locking settings for different VLANs configured
on a port need to be vetoed. To that end, veto the following scenarios:
1. Locking is set on a bridge port that is a VLAN upper
2. Locking is set on a bridge port that has VLAN uppers
3. VLAN upper is configured on a locked bridge port
Examples:
# bridge link set dev swp1.10 locked on
Error: mlxsw_spectrum: Locked flag cannot be set on a VLAN upper.
# ip link add link swp1 name swp1.10 type vlan id 10
# bridge link set dev swp1 locked on
Error: mlxsw_spectrum: Locked flag cannot be set on a bridge port that has VLAN uppers.
# bridge link set dev swp1 locked on
# ip link add link swp1 name swp1.10 type vlan id 10
Error: mlxsw_spectrum: VLAN uppers are not supported on a locked port.

mlxsw: spectrum_switchdev: Add support for locked FDB notifications
In Spectrum, learning happens in parallel to the security checks.
Therefore, regardless of the result of the security checks, a learning
notification will be generated by the device and polled later on by the
driver.
Currently, the driver reacts to learning notifications by programming
corresponding FDB entries to the device. When a port is locked (i.e.,
has security checks enabled), this can no longer happen, as otherwise
any host will blindly gain authorization.
Instead, notify the learned entry as a locked entry to the bridge driver
that will in turn notify it to user space, in case MAB is enabled. User
space can then decide to authorize the host by clearing the "locked"
flag, which will cause the entry to be programmed to the device.

bridge: switchdev: Allow device drivers to install locked FDB entries
When the bridge is offloaded to hardware, FDB entries are learned and
aged-out by the hardware. Some device drivers synchronize the hardware
and software FDBs by generating switchdev events towards the bridge.
When a port is locked, the hardware must not learn autonomously, as
otherwise any host will blindly gain authorization. Instead, the
hardware should generate events regarding hosts that are trying to gain
authorization and their MAC addresses should be notified by the device
driver as locked FDB entries towards the bridge driver.
Allow device drivers to notify the bridge driver about such entries by
extending the 'switchdev_notifier_fdb_info' structure with the 'locked'
bit. The bit can only be set by device drivers and not by the bridge
driver.
Prevent a locked entry from being installed if MAB is not enabled on the
bridge port.
If an entry already exists in the bridge driver, reject the locked entry
if the current entry does not have the "locked" flag set or if it points
to a different port. The same semantics are implemented in the software
data path.
