I'm currently configure a Netgear EX6150v2 (IPQ4018 and only one Gbit port).
I need a tagged VLAN7 on the port for my ISP Pppoe connection. The lan traffic should be untagged on the same port.
According to your explanation that's not possible, only VID1 and 2 are working like magic?
I would try setting it up like "normal" on the WAN port and the ethN.7 as appropriate.
I haven't gotten deep enough into the code to have a hypothesis of what works and what doesn't as far as config past the "normal". As running a VLAN on the WAN port is pretty normal, it may just work.
A lot of the problems I have run into seem to be related to spanning the WAN and LAN ports on the switch, especially when tagged on one port and not on others.
Thanks Jeff! Here is my current config:
config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fd7b:5eba:f476::/48'
config interface 'lan'
option type 'bridge'
option ifname 'eth0'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'
config interface 'wan'
option ifname 'eth0.7'
option proto 'pppoe'
option password 'mypw'
option username 'xxx@t-online.de'
option ipv6 'auto'
config interface 'wan6'
option ifname 'eth0.7'
option proto 'dhcpv6'
option auto '0'
I see the interface in Luci and over the CLI with ifconfig.
But when I try to connect a modem to the port the connection attempt failed. A similar config is working on the C2600 but it has a different target and an integrated switchport.
Wan should be eth1.7 I guess.
I guessed eth0 because there is only one switchport in the device and the default interface is eth0 and it's working. So I assumed to give eth0.7 a try. 
I also listed all network devices as described in the Vlan documentation and it only shows me virtual interfaces and eth0.
What does
swconfig dev switch0 show
output?
This is not the default vlan setup and it is unclear which port is used on this device.
Please reset the device to defaults and post /etc/config/network including switch config.
I think tagging is needed on the port that is actually used.
Ok. Yesterday I flashed the 18.06.2 stable build via the Netgear webinterface. Then I just added my wifi credentials and added the driver based vlan in the network config.
I will reset the device in the evening. Is more needed than a 'firstboot' command over the CLI?
I will report back the default network config and the output of 'swconfig dev switch0 show'. Thanks in advance!
Edit: I see there is the 18.06.4 available. I will flash this tonight!
firstboot is OK
I updated to the latest stable (18.06.4). What's really strange: I can't perform a firstboot from the CLI! It says it will do all the stuff but it doesn't reboot from itself.
root@OpenWrt:~# firstboot
This will erase all settings and remove any installed packages. Are you sure? [N/y]
y
/dev/mtdblock14 is mounted as /overlay, only erasing files
After it I can reboot the device and perform a factory reset with Luci. Strange!
And here are the default settings on the device:
BusyBox v1.28.4 () built-in shell (ash)

Fails on all non-JFFS2 overlays, which includes NAND/UBIFS
@jeff the workaround in the described bug report seems not to work for me. Is there a way to perform a firstboot manually?
I tried a mount_root before I ran firstboot. It didn't reboot by itself.
I think the most robust is to boot into failsafe, don't mount the overlay and then re-init the volume, truncating it with double check this first!!
root@OpenWrt:/# ubinfo /dev/ubi0_1
Volume ID: 1 (on ubi0)
Type: dynamic
Alignment: 1
Size: 953 LEBs (121008128 bytes, 115.4 MiB)
State: OK
Name: rootfs_data
Character device major/minor: 252:2
Once you're sure of the proper volume
ubiupdatevol /dev/ubi0_1 -t
root@OpenWrt:/# ubiupdatevol --help
ubiupdatevol version 2.0.2 - a tool to write data to UBI volumes.
Usage: ubiupdatevol <UBI volume node file name> [-t] [-s <size>] [-h] [-V] [--truncate]
[--size=<size>] [--help] [--version] <image file>
Example 1: ubiupdatevol /dev/ubi0_1 fs.img - write file "fs.img" to UBI volume /dev/ubi0_1
Example 2: ubiupdatevol /dev/ubi0_1 -t - wipe out UBI volume /dev/ubi0_1
-t, --truncate truncate volume (wipe it out)
-s, --size=<bytes> bytes to read from input
--skip=<bytes> leading bytes to skip from input
-h, --help print help message
-V, --version print program version
Thank you! I think it's better for me to wait for tomorrow and try it with a fresh mind. Before I have to figure out which button I can use as failsafe-button and how to perform the boot into failsafe mode.
Something like this may work
config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fd09:910b:372e::/48'
config interface 'lan'
option type 'bridge'
option ifname 'eth0'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'
config interface 'wan'
option ifname 'eth0.7'
option proto 'pppoe'
option password 'mypw'
option username 'xxx@t-online.de'
option ipv6 'auto'
config switch
option name 'switch0'
option reset '1'
option enable_vlan '1'
config switch_vlan
option device 'switch0'
option vlan '1'
option vid '1'
option ports '0 1 2 3 4'
config switch_vlan
option device 'switch0'
option vlan '7'
option vid '7'
option ports '0t 1t 2t 3t 4t'
Actually it looks like port 4 is in use. But we can use all if that is wrong.
Thanks @Pilot6. I will try it today. Something for my understanding:
Normally the CPU-port on the switch should always be tagged, shall it? In every OpenWRT router I have there is the CPU port of the switch always tagged even if the physical lan ports are untagged.
Someone also owns the EX6150v2?
Not always. The default vlan 1 config for my NBG6617 is with port 0 untagged. That means that all traffic by default goes to vlan 1 no matter is it tagged or not. It is hardcoded in dts.
You may be correct for the case when eth0 is used for both lan and wan. Change it fo 0t.
And when I am using vlans, it is still untagged on vlan 1.
config switch
option name 'switch0'
option reset '1'
option enable_vlan '1'
