The commit message says "send_event" but the code says "trigger_event".

It looks like I reported some things against
pinctrl_handle_empty_lb_backends_opts() for patch 1, that were really
introduced in this patch.  Oops.  They still are relevant though.

I don't see any documentation of the new OVN action along with the
existing ones in ovn-sb.xml.
