+ at 15 characters if longer (since that's the maximum length for network interface names). From now
+ on, for any interface name that would be longer than 15 characters the last 4 characters are set to
+ a 24bit hash value of the full interface name. This way network interface name collisions between
+ multiple similarly named containers (who only differ in container name suffix) should be less
+ likely (but still possible, since the 24bit hash value is very small).</para></listitem>
