Yes, just get rid of this 'if statement'.
in6addr_any should be represented as '::', not '*'. Otherwise it's 
impossible to distinguish IPv4 listening addresses from IPv6. Thank you :)  

But IPv6 accepts IPv4 as well.  

Not always (IPV6_V6ONLY socket option)

I agree that this recent change in ss is problematic.

Please give us back a way to distinguish IPV6 and IPv4

What about
	*:80	<< both IPV6 and IPV4
	[::]:80	<< IPV6_ONLY
	0.0.0.0:80  << IPV4_ONLY

Assuming that this will be distinguished based on INET_DIAG_SKV6ONLY
attribute, tc will then use the asterisk for v6only sockets on older
kernels not supporting the feature.

Fine with me, just a heads-up!
