In my experience this work:
config VLAN_8021Q
    tristate "802.1Q VLAN Support"
    ---help---
      Select this and you will be able to create 802.1Q VLAN interfaces
      on your ethernet interfaces.  802.1Q VLAN supports almost
      everything a regular ethernet interface does, including
      firewalling, bridging, and of course IP traffic.  You will need
      the 'vconfig' tool from the VLAN project in order to effectively
      use VLANs.  See the VLAN web page for more information:
      <http://www.candelatech.com/~greear/vlan.html>

      To compile this code as a module, choose M here: the module
      will be called 8021q.

      If unsure, say N.
