Hi Jakub,

I just realize that most of the address/src/dst in rt-addr/route are dual stack. The same with FRA_DST. We can't simply change binary to u32. So can we keep this u32 -> binary change?

Ah, should have looked at more context.. Yes, and in that case without the display-hint?

The display-hint is required; otherwise, the displayed src and dst fields appear as binary data, and setting the rule’s src/dst values also fails. I haven’t checked the code yet, but with - display-hint: ipv4 the IPv6 addresses are also displayed correctly :)

Thanks Hangbin
