By design port 3 is the trunk and all vlans should go through it
tagged. That is in fact what the switch expects.

It sure does (and thanks for the commands!)
VLAN 2:
info: VLAN 2: Ports: '0123t5t', members=002f, untag=0007, fid=0
fid: 0
ports: 0 1 2 3t 5t
VLAN 3:
info: VLAN 3: Ports: '3t5t', members=0028, untag=0000, fid=0
fid: 0
ports: 3t 5t
I also ran swconfig dev rtl8366s show to see if it would spit out
something different.
I will need to look up on this command's man page
(https://wiki.openwrt.org/doc/techref/swconfig) later. For instance,
what do the members=X and untag=Y fields report?

Interesting: I do not have vid manually defined. I ASSumed per
(https://wiki.openwrt.org/doc/uci/network/switch) it would use the
vlan number. So, if I had
# DMZ
config switch_vlan
option device rtl8366s
option vlan 3
option ports "3t 5t"
the default vid for this guy would be 3.

Mine look like this
config switch
option name rtl8366s
option reset 1
# We do want to use vlans
option enable_vlan 1
# Blinkrate: 0=43ms; 1=84ms; 2=120ms; 3=170ms; 4=340ms; 5=670ms
option blinkrate 2
which is consistent with swconfig list:
Found: switch0 - rtl8366s

Fun fact: tcpdump -i eth0.3 (Thanks David for making me stopping
be a lazy ass and installing it) in the router shows me some ARP
traffic
tcpdump: WARNING: eth0.3: no IPv4 address assigned

but when I connect a laptop on port 3 and run wireshark for 10
minutes, I see tons 802.1q vlan 2 traffic but nothing for vlan 3. That
makes me think I must have it configured wrong, which leads to me
belie I am missing something when I set openwrt up.
