A verbose dmesg of the two cases would probably be helpful.
I set verbose_loading="YES", then booted two times, once without, once
with if_smsc_load="YES".

$ diff dmesg-not-loaded.txt dmesg-loaded.txt

That's not the full dmesg, just a diff.
I was reluctant to spam the list with two full dmesg outputs if just a small
part
is probably relevant. Thought a diff would catch it.
Anyway I'll add both as an attachment - hope that passes the list server.
Yep, and the context around the last diff (the vlxan) does show it is
intertwined
with smsc0 initializing. That said, I'm still not sure why it's not always
failing
TBH. In both cases vxlan0 reports its MAC address before ue0 has even attached.
It might be useful to look at dmesg -a output to see what console messages from
userspace are firing (e.g. when the rc.d scripts run), but I doubt that will
really
tell us anything new.
A more general fix would be to add support for a 'vxlans_<IF>'
variable similar to `vlans_<IF>' which would be a list of child vxlan
interfaces. You would then just need `vxlans_ue0="vxlan0"` instead of
cloned_interfaces="vxlan0" in rc.conf.
That's actually the most interesting suggestion because shell scripting is what
I can do and I am familiar with that mechanism having used e.g. vlans_igb0...
for years. I'll try to implement and submit that possibly in the coming week.
OTOH there are still two EuroBSCCon presentations to be done, atm. :-)
I think this would also perhaps fix your original root bug you mentioned at the
start of the thread that vxlans are not created when an interface is brought up.
