+	  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.
