Sat, 06 Jun 2026 10:29:31 +0200

net: dsa: realtek: rtl8365mb: add FDB supportImplement support for FDB and MDB management for the RTL8365MB seriesswitches.The hardware supports IVL by keying the unicast forwarding database withthe {MAC, VID, EFID} tuple. The Extended Filtering ID (EFID) is 3 bitswide, providing 8 unique filtering domains. This driver reserves EFID 0for standalone ports, effectively limiting the hardware offload to amaximum of 7 bridges. The multicast database uses a {MAC, VID} key, withports from different bridges sharing the same multicast group.Introduce a mutex lock (l2_lock) to protect concurrent L2 table updates.Add support for forwarding database operations, including unicast andmulticast entry handling as well as fast aging support.Set DSA switch flags assisted_learning_on_cpu_port and fdb_isolation.Signed-off-by: Alvin Šipraga Reviewed-by: Linus Walleij Reviewed-by: Mieczyslaw Nalewaj Co-developed-by: Luiz Angelo Daros de Luca Signed-off-by: Luiz Angelo Daros de Luca Link: https://patch.msgid.link/20260606-realtek_forward-v13-7-b9e409687cbe@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux/drivers/net/dsa/realtek/Makefile

Sat, 06 Jun 2026 10:29:30 +0200

net: dsa: realtek: rtl8365mb: add VLAN supportRealtek RTL8365MB switches (a.k.a. RTL8367C family) use two differentstructures for VLANs:- VLAN4K: A full table with 4096 entries defining port membership and tagging.- VLANMC: A smaller table with 32 entries used primarily for PVID assignment.In this hardware, a port's PVID must point to an index in the VLANMCtable rather than a VID directly. Since the VLANMC table is limited to32 entries, the driver implements a dynamic allocation scheme tomaximize resource usage:- VLAN4K is treated by the driver as the source of truth for membership.- A VLANMC entry is only allocated when a port is configured to use a specific VID as its PVID.- VLANMC entries are deleted when no longer needed as a PVID by any port.Although VLANMC has a members field, the switch only checks membershipin the VLAN4K table. This driver will use VLANMC members field as way totrack which ports are using that entry as PVID.VLANMC index 0, although a valid entry, is reserved in this driver as aneutral PVID value for ports not using a specific PVID.In the subsequent RTL8367D switch family, VLANMC table wasremoved and PVID assignment was delegated to a dedicated set ofregisters.The use of FIELD_PREP for reconstructing LO/HI values was suggested byYury Norov.Fix for vlan_setup and vlan_filtering was suggested by AbdulkaderAlrezej.Suggested-by: Yury Norov Suggested-by: Abdulkader Alrezej Signed-off-by: Alvin Šipraga Reviewed-by: Linus Walleij Reviewed-by: Mieczyslaw Nalewaj Co-developed-by: Luiz Angelo Daros de Luca Signed-off-by: Luiz Angelo Daros de Luca Link: https://patch.msgid.link/20260606-realtek_forward-v13-6-b9e409687cbe@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux/drivers/net/dsa/realtek/Makefile
