>Description:
New naming scheme for vlan interfaces causes in undefined names of according netgraph nodes.

/boot/loader.conf:
ng_ether_load="YES"
ng_ksocket_load="YES"
ng_netflow_load="YES"
ng_one2many_load="YES"
ng_socket_load="YES"

/etc/rc.conf:
ifconfig_fxp0="UP"
ifconfig_em0="UP"
vlans_em0="200 201 202"
ifconfig_em0_200="10.0.1.1/30"          
ifconfig_em0_201="10.0.2.1/30"            
ifconfig_em0_202="10.0.3.1/30"

"ifconfig" shows:
em0.200: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    ...
    vlan: 200 parent interface: em0
em0.201: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    ...
    vlan: 201 parent interface: em0
em0.202: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    ...
    vlan: 202 parent interface: em0

Seems like it's ok. But look at "ngctl list":
There are 6 total nodes:
  Name: em0             Type: ether           ID: 00000001   Num hooks: 0
  Name: fxp0            Type: ether           ID: 00000002   Num hooks: 0
  Name: <unnamed>       Type: ether           ID: 00000003   Num hooks: 0
  Name: <unnamed>       Type: ether           ID: 00000004   Num hooks: 0
  Name: <unnamed>       Type: ether           ID: 00000006   Num hooks: 0
  Name: ngctl1962       Type: socket          ID: 00000009   Num hooks: 0

How am I suppose to communicate with these netgraph nodes?
