Your CPU port is untagged, it should be:
'1 2 3 4 5t'
'0 5t'
(without this CPU - or OpenWrt - doesn't know if the packet is coming
from LAN of WAN).

Also you may want to *not* use VID 0, which is a reserved value, see:

In other words... I suggest deleting /etc/config/network and rebooting
to let OpenWrt regenerate new one. Then you will have to simply
restore your changes (hint: ipaddr).

Older OpenWrt versions were using such a incomplete/invalid configs
that don't work anymore with BB+. So sysupgrade to BB is correctly
broken. I'll submit some RFC patch for it in a minute.
