But the address cannot be inherited unless the master has already been
probed. So it must be probed first, so it needs to have a lower
numbered
alias.
Are you sure, probing will depend on the aliases? eth_initialize() will
call uclass_first_device_check() which in turn returns the first device
in the linked list. I don't exactly know how they will end up in that
list, but I don't think it is by the alias.

uclass 34: eth
0 * enetc-2 @ ffd3e020, seq 2
1 * gbe0 @ ffd3e4d0, seq 0
2 * gbe1 @ ffd3e5d0, seq 1
It will also work on my board even if ethaddr is unset, enetc-2 is
probed
before the DSA ports, but if I understand you correctly, that is just by
chance; as it is on the RDB I guess then.
Anyway, if the DSA needs the parent ethernet device, shouldn't it then
be probed automatically?
