-The @emph{n} here is the number of the ethertap device you want to use.
-It should be the same @emph{n} as the one you use for
-@file{/dev/tap@emph{n}}. The @emph{xx}s are four hexadecimal numbers
-(0--ff). With previous versions of tincd, it didn't matter what they
-were. But newer kernels require properly set up ethernet addresses. In
-fact, the old behavior was wrong. It is required that the @emph{xx}s
-match the numbers of the IP address you will give to the tap device and
-to the MyOwnVPNIP configuration (which will be discussed later).
