Thanks for the detailed explanation.
So we only cache the expr tree for the flows which match on a logical port
and that logical port is not seen yet. I guess this should be fine.
Instead of doing
if (cached_expr && !lflow_ref_lookup(&l_ctx_out->lfrr->lflow_ref_table,
&lflow->header_.uuid))
We could probably do something like
if (cached_expr && !is_cr_cond_present && lookup_port_succeeded) {
// cache expr matches ..
} else {
// cache expr tree
}
..
..
lookup_port_cb() can probably set lookup_port_succeeded to false if
the lookup failed.
This would avoid the lflow_ref_lookup().

Ok. I think it would be great to enhance the test with two HVs.
