Subject: iproute2 ss: Some thoughts about additional info output layout

Hi,

I think that current output of ss utility visually looks little weird
when additional info options were specified, so I feel that a lot of
yours will say that it will break existing scripts of ss output parsing
but I will try, so thats how I think ss output would looks better in
case if additionally info options were specified (I am not sure how it
would looks in the email) :
