How to bring up interface without address?

[Lev Serebryakov]

Hello Freebsd-net,

  I have "em1" interface which is container for several vlans, but it doesn't
need any special configuration and it doesn't need IPv4 or IPv6 address.

 If I write this in /etc/rc.conf:

ifconifg_em1=""
vlans_em1="isp1 isp2"
create_args_isp1="vlan 10"
create_args_isp2="vlan 20"

ifconfig_isp1="DHCP"
ifconfig_isp2="DHCP"


 Startup script will not bring em1 UP automatically. So, I need some no-op
option for ifconifg_em1 variable. What should I use?
