This assumption turned out to be incorrect, ZII RDU2 for example uses a device base name of mv88e6xxx-30be0000.ethernet-1:0, leaving no space for post fixes such as -g1-atu-prob and -watchdog. The names then become identical, defeating the point of the patch. Increase the length of the string to 64 charactoes.
