This series introduces bridge offloading, FDB management, and VLAN support
for the Realtek rtl8365mb DSA switch driver. The primary goal is to
enable hardware frame forwarding between bridge ports, reducing CPU
overhead and providing advanced features like VLAN and FDB isolation.
Some of these patches are based on original work by Alvin Šipraga,
subsequently adapted and updated for the current net-next state.

I attempted to reach Alvin for review of the final version but was
unable to establish contact. Any regressions in this version are my
responsibility.
Changes in v3:
- Fixed kernel-doc warnings
- Removed unnecessary defensive checks
- Link to v2: https://patch.msgid.link/20260503-realtek_forward-v2-0-d064e220b391@gmail.com
Changes in v2:
- added patch to use ERR_PTR()
- dropped bitfield patch. Use FIELD_PREP instead. Suggested by Yury
Norov
- tag_rtl8_4 patches were submitted on its own series (already accepted)
- dropped rtl8365mb_vlan_mc_port_{add,del}(). rtl8365mb_vlan_mc_port_set
is now called directly from PVID methods.
- reordered methods in rtl8365mb_vlan.c
- use dsa_switch_for_each_user_port() instead of simple for in bridge
port join/leave
- PVID check now uses dsa_switch_for_each_available_port instead of
dsa_switch_for_each_port
- set EFID of user ports to 0 at setup(), although it is the expected
state after reset
- STP patch was dropped and replaced by a more extensive one that
disables all ports (including unused ones) before setting CPU and user
ports. It also extended the CPU port isolation to include all user
ports.
- refactored bridge, FDB, and MDB port operations into the common
rtl83xx module, introducing new realtek_ops callbacks to abstract the
hardware access
- Collected Reviewed-by and Suggested-by tags
