+		    LINUX: 802.1q VLAN INTERFACES
+
+If you're using 802.1q vlan interfaces on Linux, it is necessary to
+vconfig the subinterface(s) to rewrite the 802.1q information out of
+packets received by the dhcpd daemon via LPF:
+
+	vconfig set_flag eth1.523 1 1
+
+Note that this may affect the performance of your system, since the
+Linux kernel must rewrite packets received via this interface.  For
+more information, consult the vconfig man pages.

 The DHCP client on Solaris will only work with DLPI.  If you run it
 and it just keeps saying it's sending DHCPREQUEST packets, but never
 gets a response, you may be having DLPI trouble as described above.
-If so, we have no solution to offer at this time.  Also, because
-Solaris requires you to "plumb" an interface before it can be detected
-by the DHCP client, you must either specify the name(s) of the
-interface(s) you want to configure on the command line, or must plumb

 It should be noted that Solaris versions from 2.6 onward include a
 DHCP client that you can run with ``/sbin/ifconfig iface dhcp start''
