Subject: [iproute2] regression in ss output

Hi! With the last iproute2 release, ss command output does not 
differentiate between any-address IPv4 sockets from the IPv6 ones.
I don't know if this is an expected behaviour, but the old output looks 
more useful. Below I pasted the difference between the old behaviour and 
the new one.
I am happy to send a patch if you want. Thanks
