Not quite, seem like the name part is not working as expected. 
I just tested it on 6.0 and the part coming after name vlan_to_somewhere is not being executed
although the same thing works with ath:
ifconfig_ath0="name wlan0 inet 192.168.13.1 netmask 255.255.255.0 ssid YazzY mode 11g channel 10 mediaopt hostap up"
