In case of a tc mirred action from one switch to another, the behavior
is not correct. We simply tell the source switch driver to program a
mirroring entry towards mirror->to_local_port = to_dp->index, but it is
not even guaranteed that the to_dp belongs to the same switch as dp.
For proper cross-chip support, we would need to go through the
cross-chip notifier layer in switch.c, program the entry on cascade
ports, and introduce new, explicit API for cross-chip mirroring, given
that intermediary switches should have introspection into the DSA tags
passed through the cascade port (and not just program a port mirror on
the entire cascade port). None of that exists today.
Reject what is not implemented so that user space is not misled into
thinking it works.
