Vlad,

Yes, I was breaking into multiples to ease review only.
The "[PATCH 01/04] ... (5)" thread includes the complete
reviewable and patchable final text in 4 files. In my
next message, I will put the entire patchfile as inline
text. (The "[PATCH 01/01] ... (5)" for 'iproute2' is
already complete.)

Thanks - Fred
