A quick test on 14.2-p1,

```

# ifconfig lagg0 laggport epair0a
# ifconfig lagg0

        groups: lagg
        media: Ethernet autoselect
        status: no carrier
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

# ifconfig lagg0.300
lagg0.300: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1496
        options=0
        ether 02:3b:b3:8f:9a:0a
        groups: vlan
        vlan: 300 vlanproto: 802.1q vlanpcp: 0 parent interface: lagg0
        media: Ethernet autoselect
        status: no carrier
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
```

The ether address of vlan lagg0.300 is updated correctly when a port member is
added to lagg interface.

I think this issue has been fixed.
