[ Upstream commit 4250ff1640ea1ede99bfe02ca949acbcc6c0927f ]

The MxL862xx offloads bridge forwarding in hardware, so set
dsa_default_offload_fwd_mark() to avoid duplicate forwarding of
packets of (eg. flooded) frames arriving at the CPU port.

Link-local frames are directly trapped to the CPU port only, so don't
set dsa_default_offload_fwd_mark() on those.

LLM Generated explanations, may be completely bogus:

Now I have all the information needed for a complete analysis.

This commit should NOT be backported, it only makes sense with bridge
offloading implemented, which only happened with commit 340bdf984613c
("net: dsa: mxl862xx: implement bridge offloading").

ack, dropped.
