Too many things are squashed into this one patchset. It needs to be
split. According to the title, the patchset is focused on improving
performance, but there are no performance numbers that I could see and
most of the patches deal with the replay stuff instead.

The TX forwarding offload in mv88e6xxx is not related to the replay
stuff and should be added in a separate patchset. This can be done by
first adding the switchdev_bridge_port_offload() /
switchdev_bridge_port_unoffload() APIs that only take care of setting /
unsetting the hardware domain for the bridge port. Then, in a different
patchset, these APIs can be augmented with a parameter for the replay
stuff. It should be easier to review that way and require less
unnecessary surgeries in drivers that do not require the added
functionality.

Thanks
