> This series adds bridge mode support to the NETC DSA switch driver, > covering both VLAN-aware and VLAN-unaware operation. > > The NETC switch manages forwarding through a set of hardware tables > accessed via NTMP: the FDB table (FDBT), VLAN filter table (VFT), egress > treatment table (ETT), and egress count table (ECT). The series extends > the NTMP layer with the operations required for bridging, then builds the > DSA bridge callbacks on top. > > Since all switch ports share the VFT, so only one VLAN-aware bridge is > supported. > > FDB aging is managed in software. A periodic delayed work sweeps the > table using the hardware activity element mechanism, with a default aging > time of 300 seconds matching the IEEE 802.1Q standard. Per-port entries > are also flushed immediately on bridge leave and link-down events. > > Wei Fang (9): > net: enetc: add interfaces to manage FDB entries > net: enetc: add "Update" and "Delete" operations to VLAN filter table > net: enetc: add interfaces to manage egress treatment table > net: enetc: add "Update" operation to the egress count table > net: dsa: netc: initialize the group bitmap of ETT and ECT > net: enetc: add helpers to set/clear table bitmap > net: dsa: netc: add VLAN filter table and egress treatment management > net: dsa: netc: add bridge mode support > net: dsa: netc: implement dynamic FDB entry aging > > drivers/net/dsa/netc/netc_main.c | 882 > +++++++++++++++++- > drivers/net/dsa/netc/netc_switch.h | 34 + > drivers/net/dsa/netc/netc_switch_hw.h | 6 + > drivers/net/ethernet/freescale/enetc/ntmp.c | 431 +++++++++ > .../ethernet/freescale/enetc/ntmp_private.h | 14 + > include/linux/fsl/ntmp.h | 60 ++ > 6 files changed, 1413 insertions(+), 14 deletions(-) > > -- > 2.34.1
Sashi reported some issues for this series: [1] https://sashiko.dev/#/patchset/20260527100217.794987-1-wei.fang%40oss.nxp.com [2] https://netdev-ai.bots.linux.dev/sashiko/#/patchset/20260527100217.794987-1-wei.fang%40oss.nxp.com Some of them are indeed potential issues, I will fix them in next version. Any other comments are welcome, thanks. -- pw-bot: cr
