====================
spi: Make remove() return void
This series from Uwe Kleine-König converts the spi remove function to
return void since there is nothing useful that we can do with a failure
and it as more buses are converted it'll enable further work on the
driver core.

As more police parameters are passed to flow_offload, driver can check
them to make sure hardware handles packets in the way indicated by tc.
The conform-exceed control should be drop/pipe or drop/ok. Besides,
for drop/ok, the police should be the last action. As hardware can't
configure peakrate/avrate/overhead, offload should not be supported if
any of them is configured.

Currently ocelot uses a pvid of 0 for standalone ports and ports under a
VLAN-unaware bridge, and the pvid of the bridge for ports under a
VLAN-aware bridge. Standalone ports do not perform learning, but packets
received on them are still subject to FDB lookups. So if the MAC DA that
a standalone port receives has been also learned on a VLAN-unaware
bridge port, ocelot will attempt to forward to that port, even though it
can't, so it will drop packets.
So there is a desire to avoid that, and isolate the FDBs of different
bridges from one another, and from standalone ports.
The ocelot switch library has two distinct entry points: the felix DSA
driver and the ocelot switchdev driver.
We need to code up a minimal bridge_num allocation in the ocelot
switchdev driver too, this is copied from DSA with the exception that
ocelot does not care about DSA trees, cross-chip bridging etc. So it
only looks at its own ports that are already in the same bridge.
The ocelot switchdev driver uses the bridge_num it has allocated itself,
while the felix driver uses the bridge_num allocated by DSA. They are
both stored inside ocelot_port->bridge_num by the common function
ocelot_port_bridge_join() which receives the bridge_num passed by value.
Once we have a bridge_num, we can only use it to enforce isolation
between VLAN-unaware bridges. As far as I can see, ocelot does not have
anything like a FID that further makes VLAN 100 from a port be different
to VLAN 100 from another port with regard to FDB lookup. So we simply
deny multiple VLAN-aware bridges.
For VLAN-unaware bridges, we crop the 4000-4095 VLAN region and we
allocate a VLAN for each bridge_num. This will be used as the pvid of
each port that is under that VLAN-unaware bridge, for as long as that
bridge is VLAN-unaware.
VID 0 remains only for standalone ports. It is okay if all standalone
ports use the same VID 0, since they perform no address learning, the
FDB will contain no entry in VLAN 0, so the packets will always be
flooded to the only possible destination, the CPU port.
The CPU port module doesn't need to be member of the VLANs to receive
packets, but if we use the DSA tag_8021q protocol, those packets are
part of the data plane as far as ocelot is concerned, so there it needs
to. Just ensure that the DSA tag_8021q CPU port is a member of all
reserved VLANs when it is created, and is removed when it is deleted.

This adds the logic in the Felix DSA driver and Ocelot switch library.
For Ocelot switches, the DEST_IDX that is the output of the MAC table
lookup is a logical port (equal to physical port, if no LAG is used, or
a dynamically allocated number otherwise). The allocation we have in
place for LAG IDs is different from DSA's, so we can't use that:
- DSA allocates a continuous range of LAG IDs starting from 1
- Ocelot appears to require that physical ports and LAG IDs are in the
same space of [0, num_phys_ports), and additionally, ports that aren't
in a LAG must have physical port id == logical port id
The implication is that an FDB entry towards a LAG might need to be
deleted and reinstalled when the LAG ID changes.

When the switchdev_handle_fdb_event_to_device() event replication helper
was created, my original thought was that FDB events on LAG interfaces
should most likely be special-cased, not just replicated towards all
switchdev ports beneath that LAG. So this replication helper currently
does not recurse through switchdev lower interfaces of LAG bridge ports,
but rather calls the lag_mod_cb() if that was provided.
No switchdev driver uses this helper for FDB events on LAG interfaces
yet, so that was an assumption which was yet to be tested. It is
certainly usable for that purpose, as my RFC series shows:
https://patchwork.kernel.org/project/netdevbpf/cover/20220210125201.2859463-1-vladimir.oltean@nxp.com/
however this approach is slightly convoluted because:
- the switchdev driver gets a "dev" that isn't its own net device, but
rather the LAG net device. It must call switchdev_lower_dev_find(dev)
in order to get a handle of any of its own net devices (the ones that
pass check_cb).
- in order for FDB entries on LAG ports to be correctly refcounted per
the number of switchdev ports beneath that LAG, we haven't escaped the
need to iterate through the LAG's lower interfaces. Except that is now
the responsibility of the switchdev driver, because the replication
helper just stopped half-way.
So, even though yes, FDB events on LAG bridge ports must be
special-cased, in the end it's simpler to let switchdev_handle_fdb_*
just iterate through the LAG port's switchdev lowers, and let the
switchdev driver figure out that those physical ports are under a LAG.
The switchdev_handle_fdb_event_to_device() helper takes a
"foreign_dev_check" callback so it can figure out whether @dev can
autonomously forward to @foreign_dev. DSA fills this method properly:
if the LAG is offloaded by another port in the same tree as @dev, then
it isn't foreign. If it is a software LAG, it is foreign - forwarding
happens in software.
Whether an interface is foreign or not decides whether the replication
helper will go through the LAG's switchdev lowers or not. Since the
lan966x doesn't properly fill this out, FDB events on software LAG
uppers will get called. By changing lan966x_foreign_dev_check(), we can
suppress them.
Whereas DSA will now start receiving FDB events for its offloaded LAG
uppers, so we need to return -EOPNOTSUPP, since we currently don't do
the right thing for them.

For RX TLS device-offloaded packets, the HW spec guarantees checksum
validation for the offloaded packets, but does not define whether the
CQE.checksum field matches the original packet (ciphertext) or
the decrypted one (plaintext). This latitude allows architetctural
improvements between generations of chips, resulting in different decisions
regarding the value type of CQE.checksum.
Hence, for these packets, the device driver should not make use of this CQE
field. Here we block CHECKSUM_COMPLETE usage for RX TLS device-offloaded
packets, and use CHECKSUM_UNNECESSARY instead.
Value of the packet's tcp_hdr.csum is not modified by the HW, and it always
matches the original ciphertext.

Only prio 1 is supported if firmware doesn't support ignore flow
level for nic mode. The offending commit removed the check wrongly.
Add it back.

Match metadata support check returns false for ecpf device.
However, this support does exist for ecpf and therefore this
limitation should be removed to allow feature such as stacked
devices and internal port offloaded to be supported.

Currently, log_max_qp value is dependent on what FW reports as its max capability.
In reality, due to a bug, some FWs report a value greater than 17, even though they
don't support log_max_qp > 17.
This FW issue led the driver to exhaust memory on startup.
Thus, log_max_qp value is set to be no more than 17 regardless
of what FW reports, as it was before the cited commit.

When deciding whether to start syncing and actually free all the "hot"
ICM chunks, we need to consider the type of the ICM chunks that we're
dealing with. For instance, the amount of available ICM for MODIFY_ACTION
is significantly lower than the usual STE ICM, so the threshold should
account for that - otherwise we can deplete MODIFY_ACTION memory just by
creating and deleting the same modify header action in a continuous loop.
This patch replaces the hard-coded threshold with a dynamic value.

Currently SMFS allows adding rule with matching on src/dst IP w/o matching
on full ethertype or ip_version, which is not supported by HW.
This patch fixes this issue and adds the check as it is done in DMFS.

When adding a rule with 32 destinations, we hit the following out-of-band
access issue:
BUG: KASAN: slab-out-of-bounds in mlx5_cmd_dr_create_fte+0x18ee/0x1e70
This patch fixes the issue by both increasing the allocated buffers to
accommodate for the needed actions and by checking the number of actions
to prevent this issue when a rule with too many actions is provided.
Fixes: 1ffd498901c1 ("net/mlx5: DR, Increase supported num of actions to 32")
