>Description:
Old rc.conf syntax that seems to create all our interfaces but can't handle aliases:

ifconfig_em0="UP"
cloned_interfaces="vlan5"
ifconfig_vlan5="inet 192.168.5.10/24 vlan 5 vlandev em0" # works
ifconfig_vlan5_alias0="inet 192.168.5.11 alias" # does not work
ifconfig_vlan5_alias1="inet 192.168.5.12 alias vlan 5 vlandev em0" # does not work
ifconfig_vlan5_ipv6="inet6 2607:XXXX:100:111::18/64" # does not work (IP censored)


Newer rc.conf syntax that does work:

ifconfig_em0="UP"
vlans_em0="vlan5"
create_args_vlan5="vlan 5"

ifconfig_vlan5="inet 192.168.5.10/24 vlan 5 vlandev em0" # works
ifconfig_vlan5_alias0="inet 192.168.5.11 alias" # works
ifconfig_vlan5_ipv6="inet6 2607:XXXX:100:111::18/64" # works (IP censored)
ifconfig_vlan5_alias1="inet6 2607:XXXX:100:111::19/64" # also works


Should the older syntax work at all? I believe it did somewhere on older releases but I can't be certain.
