Did a brief testing for both iputils ping and busybox ping.

Hi Alexey,

BTW -f does not require root (but effectively it's required by netns setup).

Out of curiosity, why flood ping is better than -i 0?
More effective stressing?

Ad Busybox ping fallback -i 0.01, interesting -i 0 keeps blocked in
recvfrom():

Hi Petr,

Are sure -f doesn't require root?

I think it's better to use the option that is specially made
for this, isn't it? AFAIK, -f won't do verbose printing, though
we could add -q too along with -i 0...

Sorry, I was wrong (tested on latest iputils release):

ping localhost -f
ping: cannot flood; minimal interval allowed for user is 200ms
