Are you sure the "port" selector represents the Ethernet port default
priority? It seems odd for it to have any other trust order in hardware
than last. What would be the use case for that? Sure it's not an L4 port,
which could be mapped over IEEE_8021QAZ_APP_SEL_ANY?

No (with the "port" selector) but I'm wondering, do we have
corresponding port prio methods
port_add_stream_prio()/port_add_dgram_prio() or something like?

No, but it doesn't mean dsa_user_dcbnl_ieee_setapp() can't be extended
with the IEEE_8021QAZ_APP_SEL_ANY selector if necessary. I wouldn't
bother to do that just for testing, though, just hack something up to
determine what it's about.
