 Through DSA every port of a switch is handled like a normal linux Ethernet
 interface. The CPU port is the switch port connected to an Ethernet MAC chip.

+The user interfaces depend on the conduit interface being up in order for them
+to send or receive traffic. Prior to kernel v5.12, the state of the conduit
 interface had to be managed explicitly by the user. Starting with kernel v5.12,
 the behavior is as follows:
 
-- when a DSA slave interface is brought up, the master interface is
+- when a DSA user interface is brought up, the conduit interface is
   automatically brought up.
-- when the master interface is brought down, all DSA slave interfaces are
+- when the conduit interface is brought down, all DSA user interfaces are
   automatically brought down.
 
 In this documentation the following Ethernet interfaces are used:
 
 *eth0*
-  the master interface
+  the conduit interface
 
 *eth1*
-  another master interface
+  another conduit interface
 
 *lan1*
-  a slave interface
+  a user interface
 
 *lan2*
-  another slave interface
+  another user interface
 
 *lan3*
-  a third slave interface
+  a third user interface
 
 *wan*
-  A slave interface dedicated for upstream traffic
+  A user interface dedicated for upstream traffic
 
 Further Ethernet interfaces can be configured similar.
