Hi Ulrich,

looking at iproute2 I found this patch:

http://git.kernel.org/cgit/linux/kernel/git/shemminger/iproute2.git/commit/ip/ipaddress.c?id=ccdcbf35f120c754660b3b3f48fa67cc950a6407

Due to the fact that the kernel now provides the new attribute we get this 
@NONE stuff for interfaces that have no iflink value.

This definitely is @UGLY !

@Nicloas: Why don't you just omit the @NONE when iflink is zero in the new 
attribute?

Regards,
Oliver
