net: dsa: motorcomm: Extend ACL with UDF

2026-10-21T11:36:53+00:00

The native ACL key set cannot express IP TTL or ICMP type/code. Use the
User Defined Filter windows to match them in the tc flower offload.

net: dsa: motorcomm: Enable ACL on demand

2026-10-17T00:25:13+00:00

Track the usage of ACL rules and enable it per port only when it is
actually used. This is aligned with ODM recommendations and helps reduce
latency.

net: dsa: motorcomm: Split MIB buffers

2026-10-08T23:26:15+00:00

With MIB improvement introduced later, struct yt921x_priv will be over
20 KiB which is not very good for a single kmalloc(). Dynamically
allocate the MIB structures to reduce the size of struct yt921x_priv
(and adjust polling work lifecycle), and do not waste memory on dummy
ports.

net: dsa: motorcomm: Hoist port_to_priv helper into chip.h

2026-09-26T00:15:23+00:00

yt921x_poll_mib() open-codes the same container_of_const() expression
that leds.c defines as to_yt921x_priv(). Move the macro to chip.h as
yt921x_port_to_priv() so both files use one definition.
