**Description:**

LAN bridge br-lan => eth0.3 eth0.4 eth0.5 eth0.6
WAN bridge br-wan => eth0.2

**#cat /etc/config/network**

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 'fd7f:4a91:b9ee::/48'

config interface 'lan'
        option ifname 'eth0.3 eth0.4 eth0.5 eth0.6'
        option force_link '1'
        option macaddr '00:60:2F:3b:99:97'
        option type 'bridge'
        option proto 'static'
        option netmask '255.255.255.0'
        option ip6assign '60'
        option ipaddr '192.168.2.254'

config interface 'wan'
        option ifname 'eth0.2'
        option force_link '1'
        option macaddr '00:60:2F:3B:99:96'
        option proto 'dhcp'
        option type 'bridge'

config interface 'wan6'
        option ifname 'eth0.2'
        option proto 'dhcpv6'

but 

root at openwrt:/# ifconfig | grep HWaddr
br-lan    Link encap:Ethernet  HWaddr 00:60:2F:3B:99:97  
br-wan    Link encap:Ethernet  HWaddr 00:60:2F:3B:99:96  
eth0      Link encap:Ethernet  HWaddr A2:FB:75:24:9C:FB  
eth0.2    Link encap:Ethernet  HWaddr A2:FB:75:24:9C:FB
eth0.3    Link encap:Ethernet  HWaddr A2:FB:75:24:9C:FB  
eth0.4    Link encap:Ethernet  HWaddr A2:FB:75:24:9C:FB  
eth0.5    Link encap:Ethernet  HWaddr A2:FB:75:24:9C:FB  
eth0.6    Link encap:Ethernet  HWaddr A2:FB:75:24:9C:FB  

eth0, eth0.2, eth0.3, eth0.4, eth0.5, eth0.6 MAC address is random and changes for every boot.

netifd is too far complex for the simple setting in shell scripts in earlier versions.

This is persistent and difficult to trace and fix.
I guess this is netifd bug and should exists for all SoC supported.
I am still working on netifd tracing and bug fixing.
