23 Later kernel marks some drivers interface names "predictable" or
24 "stable", not sure which word is best to use here, and then udev
25 won't rename it by default to anything. The kernel assigned name
26 could be anything, and I doubt it's in the eth* namespace
27 And they can still be renamed by custom rules, that won't change,
28 it's just that they won't get renamed by *default* anymore
