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:
Before:
iperf3 -c 10.96.10.1 -R
[  5]   0.00-10.01  sec   514 MBytes   430 Mbits/sec    0         sender
[  5]   0.00-10.00  sec   509 MBytes   427 Mbits/sec              receiver

After:
iperf3 -c 10.96.10.1 -R
[  5]   0.00-10.02  sec   540 MBytes   452 Mbits/sec    0         sender
[  5]   0.00-10.01  sec   537 MBytes   450 Mbits/sec              receiver

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

v1->v2:
- rebase on net-next, once the fixes for FDMA and MTU were accepted
- drop patch 2, which changes the MTU as is not needed anymore
- allow to run xdp programs on frames bigger than 4KB

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.

Use a tc matchall rule with a goto action to the VCAP specific chain to
enable the VCAP lookups.
If the matchall rule is removed the VCAP lookups will be disabled
again using its cookie as lookup to find the VCAP instance.

To enable the Sparx5 IS2 VCAP on eth0 you would use this command:

    tc filter add dev eth0 ingress prio 5 handle 5 matchall \
        skip_sw action goto chain 8000000

as the first lookup in IS2 has chain id 8000000

This tries to match the keys in a rule with the keysets supported by the

This list is then validated against the list of keysets that is currently

This adds the following TC flower filter keys to Sparx5 for IS2:

- 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)

as well as an 128 bit keyfield interface on the VCAP API to set the IPv6
addresses.

IS2 supports the classified VLAN information which amounts to the outer
VLAN info in case of multiple tags.

Here are some examples of the tc flower filter operations that are now
supported for the IS2 VCAP:

- IPv4 Addresses
    tc filter add dev eth12 ingress chain 8000000 prio 12 handle 12 \
        protocol ip flower skip_sw dst_ip 1.0.1.1 src_ip 2.0.2.2    \
        action trap action goto chain 81000000

- IPv6 Addresses
    tc filter add dev eth12 ingress chain 8000000 prio 13 handle 13 \
        protocol ipv6 flower skip_sw dst_ip 1::1:1 src_ip 2::2:2    \
        action trap action goto chain 81000000

- IPv4 fragments
    tc filter add dev eth12 ingress chain 8000000 prio 14 handle 14 \
        protocol ip flower skip_sw dst_ip 3.0.3.3 src_ip 2.0.2.2    \
        ip_flags frag/nofirstfrag action trap action goto chain 81000000

- TCP and UDP portnumbers
    tc filter add dev eth12 ingress chain 8000000 prio 21 handle 21 \
        protocol ip flower skip_sw dst_ip 8.8.8.8 src_ip 2.0.2.2    \
        ip_proto tcp dst_port 100 src_port 12000 action trap action goto
        chain 81000000
    tc filter add dev eth12 ingress chain 8000000 prio 23 handle 23 \
        protocol ipv6 flower skip_sw dst_ip 5::5:5 src_ip 2::2:2    \
        ip_proto tcp dst_port 300 src_port 13000 action trap action goto
        chain 81000000

- Layer 3 and Layer 4 protocol info
    tc filter add dev eth12 ingress chain 8000000 prio 28 handle 28 \
        protocol ipv4 flower skip_sw dst_ip 9.0.9.9 src_ip 2.0.2.2  \
        ip_proto icmp action trap action goto chain 81000000

- VLAN tag info (outer tag)
    tc filter add dev eth12 ingress chain 8000000 prio 29 handle 29 \
        protocol 802.1q flower skip_sw vlan_id 600 vlan_prio 6      \
        vlan_ethtype ipv4 action trap action goto chain 81000000
    tc filter add dev eth12 ingress chain 8000000 prio 31 handle 31 \
        protocol 802.1q flower skip_sw vlan_id 600 vlan_prio 5      \
        vlan_ethtype ipv6 action trap action goto chain 81000000

- TCP flags
    tc filter add dev eth12 ingress chain 8000000 prio 15 handle 15 \
        protocol ip flower skip_sw dst_ip 4.0.4.4 src_ip 2.0.2.2    \
        ip_proto tcp tcp_flags 0x2a/0x3f action trap action goto chain
        81000000

- IP info (IPv4 TOS field)
    tc filter add dev eth12 ingress chain 8000000 prio 16 handle 16 \
        protocol ip flower skip_sw ip_tos 0x35 dst_ip 5.0.5.5       \
        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
    ip link set eth14 master br5
    ip link set eth15 master br5
    sysctl -w net.ipv6.conf.eth12.disable_ipv6=1
    sysctl -w net.ipv6.conf.eth13.disable_ipv6=1
    sysctl -w net.ipv6.conf.eth14.disable_ipv6=1
    sysctl -w net.ipv6.conf.eth15.disable_ipv6=1
    sysctl -w net.ipv6.conf.br5.disable_ipv6=1
    ip link set dev br5 type bridge vlan_filtering 1
    bridge vlan add dev eth12 vid 600
    bridge vlan add dev eth13 vid 600
    bridge vlan add dev eth14 vid 600
    bridge vlan add dev eth15 vid 600

It's not necessary to free netdev allocated with devm_alloc_etherdev()

Jonathan reports crashes when running net-next in Meta's fleet.
Stats collection uses ethtool -I which does a per-op policy dump
to check if stats are supported. We don't initialize the dumpit
information if doit succeeds due to evaluation short-circuiting.

The crash may look like this:

   BUG: kernel NULL pointer dereference, address: 0000000000000cc0
   RIP: 0010:netlink_policy_dump_add_policy+0x174/0x2a0

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
name and the bus_info. If the driver provides values, do nothing.

   stack trace, syzbot has reported many

 - zoned fixes:
      - fix locking imbalance during scrub
      - initialize zones for seeding device
      - initialize zones for cloned device structures

 - when looking up device, change assertion to a real check as some of
   the search parameters can be passed by ioctl, reported by syzbot
