RE: [PATCH net-next 0/9] net: dsa: netc: add bridge mode support

[Wei Fang]

> 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.

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.
