net: dsa: mxl862xx: add support for bridge offloading

As a next step to complete the mxl862xx DSA driver, add support for offloading forwarding between bridged ports to the switch hardware.

This works pretty much without any big surprises, apart from two subtleties:
* per-port control over flooding behavior has to be implemented by (ab)using a 0-rate QoS meters as stopper in lack of any better option.
* STP state transition unconditionally enables learning on a port even if it was previously explicitely disabled (a firmware bug)

Note that as the driver is still lacking all VLAN features (which are going to be added next), at this point some of the bridge_vlan_aware.sh tests are failing after applying this series.

This is expected and cannot be avoided without implementing port_vlan_filtering + port_vlan_add/del. And adding both bridge and VLAN offloading at the same time would be too much for anyone to review, so VLAN support is going to be submitted in a follow-up series immediately after this series has been accepted.

All other relevant selftests (including bridge_vlan_unaware.sh) are still passing.

Inspired by the comments received from Paolo Abeni as reply to v5 the driver now no longer caches bridge port membership in the driver, but instead imports an existing helper from yt921x.c to dsa.h in order to allow the driver to easily iterate over bridge members. The mapping between DSA bridge num and firmware bridge ID is done using a simple fixed-size array in mxl862xx_priv.

Changes since v7:
* add missing fields to kernel-doc for struct mxl862xx_priv
* const'ify some function parameters

Changes since v6:
* drop wrong addition of 'priv' pointer to struct dsa_bridge -> use simple array to track firmware bridge to dsa bridge mapping
* move existing dsa_bridge_ports() helper from yt921x.c to dsa.h
* replace propesed dsa_bridge_for_each_member() by new dsa_switch_for_each_bridge_member() taking (struct net_device *) instead of (struct dsa_bridge *), aligned with the existing helpers
* fix bridge allocation resource leak in case of mxl862xx_sync_bridge_members() failing for the first port to join a bridge
* zero-initialize struct mxl862xx_cfg in mxl862xx_set_ageing_time
* set initial=1 to always reset cursor at start when interating over FDB in .fdb_dump
* hack zero-rate meter to truly always block
* use asynchronous worker for port_set_host_flood which runs from atomic context and hence cannot sleep
* reorder function to minimize diffstat of planned follow-up commits

Changes since v5:
* add new DSA helpers to interate over bridge members
* add driver-private pointer to struct dsa_bridge
* eliminate struct mxl862xx_bridge and driver-private bridge list, store firmware bridge FID in new dsa_bridge->priv instead
* rework sync_bridge_members() to use dsa_bridge_for_each_member() instead of for_each_set_bit() on driver-private portmap
* rework port_bridge_join/leave to use dsa_bridge.priv for first- member detection and dsa_bridge_ports() for empty-bridge check
* derive active FID from dp->bridge->priv in set_bridge_port()
* simplify allocate_bridge()/free_bridge() to take struct dsa_bridge pointer directly, drop kzalloc/kfree/list management
* simplify get_fid() to read db.bridge.priv directly
* remove mxl862xx_find_bridge()
* remove unnecessary default bridge config call in setup()

Changes since v4:
* move link-local check before dsa_strip_etype_header()
* introduce port_map helpers
* properly implement port_mdb_{add,del} operations

Changes since v3:
* add missing cpu_to_le32 in mxl862xx_bridge_config_fwd()
* use little-endian 32-bit type for (unused) age_timer API field
* better comment in port_set_host_flood() documenting architectural limitation
* fix typo in comment "matche" should be "matches"
* few whitespace fixes

Changes since v2:
* refactor .port_bridge_join and .port_bridge_leave as requested by Vladimir Oltean
* include linux/etherdevice.h which was missing and causing build to fail (it accidentally slipped into a follow-up patch)
* remove left-over manual reset of learning state for port leaving bridge
* remove unnecessary call to mxl862xx_port_fast_age() for port leaving bridge
* add kernel-doc comments in mxl862xx.h instead of sporadic inline comments covering only some of the struct members
* some other minor cosmetics (linebreaks, whitespace) here and there

Changes since v1:
* don't set dsa_default_offload_fwd_mark() on link-local frames
* fix kernel-doc comments in API header
* use bitfield helpers for compound tci field in fdb API
* add missing endian conversion for mxl862xx_stp_port_cfg.port_state as well as mxl862xx_mac_table_read.tci (spotted by AI review)
* drop manually resetting port learning state on bridge<->standalone transitions, DSA framework takes care of that
* don't abort updating bridge ports on error, return error at the end
* report error in mxl862xx_port_bridge_leave()
* create mxl862xx_get_fid() helper and use it in mxl862xx_port_fdb_add() and mxl862xx_port_fdb_del()
* propagete error of callback function in mxl862xx_port_fdb_dump()
* manually mxl862xx_port_fast_age() in mxl862xx_port_stp_state_set() to avoid FDB poisoning due to race condition

2.53.0

The yt921x driver contains a helper to create a bitmap of ports which are members of a bridge.

Move the helper as static inline function into dsa.h, so other driver can make use of it as well.

2.53.0

Drivers that offload bridges need to iterate over the ports that are members of a given bridge, for example to rebuild per-port forwarding bitmaps when membership changes. Currently drivers typically open-code this by combining dsa_switch_for_each_user_port() with a dsa_port_offloads_bridge_dev() check, or cache bridge membership within the driver.

Add dsa_switch_for_each_bridge_member() macro to express this pattern directly, and use it for the existing dsa_bridge_ports() inline helper.

2.53.0

The MxL862xx offloads bridge forwarding in hardware, so set dsa_default_offload_fwd_mark() to avoid duplicate forwarding of packets of (eg. flooded) frames arriving at the CPU port.

Link-local frames are directly trapped to the CPU port only, so don't set dsa_default_offload_fwd_mark() on those.

2.53.0

Implement joining and leaving bridges as well as add, delete and dump operations on isolated FDBs, port MDB membership management, and setting a port's STP state.

The switch supports a maximum of 63 bridges, however, up to 12 may be used as "single-port bridges" to isolate standalone ports. Allowing up to 48 bridges to be offloaded seems more than enough on that hardware, hence that is set as max_num_bridges.

A total of 128 bridge ports are supported in the bridge portmap, and virtual bridge ports have to be used eg. for link-aggregation, hence potentially exceeding the number of hardware ports.

The firmware-assigned bridge identifier (FID) for each offloaded bridge is stored in an array used to map DSA bridge num to firmware bridge ID, avoiding the need for a driver-private bridge tracking structure. Bridge member portmaps are rebuilt on join/leave using dsa_switch_for_each_bridge_member().

As there are now more users of the BRIDGEPORT_CONFIG_SET API and the state of each port is cached locally, introduce a helper function mxl862xx_set_bridge_port(struct dsa_switch *ds, int port) which is then used to replace the direct calls to the API in mxl862xx_setup_cpu_bridge() and mxl862xx_add_single_port_bridge().

Note that there is no convenient way to control flooding on per-port level, so the driver is using a 0-rate QoS meter setup as a stopper in lack of any better option. In order to be perfect the firmware-enforced minimum bucket size is bypassed by directly writing 0s to the relevant registers -- without that at least one 64-byte packet could still pass before the meter would change from 'yellow' into 'red' state.
