Hi,

We're seeing exactly this on upgrading from 10.2-RELEASE to 10.3-RELEASE-p5 --
only one machine out of about 10 that have been upgraded.  

Workaround is to set the ether address via rc.conf by adding:

```
ifconfig_vlan110="ether 90:b1:1c:41:93:50 up"
```

Config settings:
```
ifconfig_bge0="up"
ifconfig_bge1="up"

ifconfig_lagg0="laggproto lacp laggport bge0 laggport bge1 up"

cloned_interfaces="lagg0 vlan110"
vlans_lagg0="vlan110"
create_args_vlan110="vlandev lagg0 vlan 110"
ifconfig_vlan110="ether 90:b1:1c:41:93:50 up"
ipv4_addrs_vlan110="10.2.1.9/24"
defaultrouter="10.2.1.1"
```

Machine is a Dell R420 -- we're seeing the same effect with both the on-board
bge(4) NICs and with an add-on igb(4) card.

This setup has been working flawlessly for us on numerous machines since around
9.0-RELEASE
