The equivalent testing, in more detail than that, is implemented by the
patch (under review) at:

  https://lore.kernel.org/all/20250407174048.21272-4-fw@strlen.de/

You can add more tests on top on the new one in nft_concat_range.sh,
but it's not doable to test every single bit, because there are 2 ^ 128
possible IPv6 addresses. I guess you could add a test looping on bytes
or groups of 16 bits.

netfilter doesn't use GitHub. See:
