Alternatively, if another way to achieve a setup that roughly
says “all packets going to IP 1.2.3.4 into handle 1:2, all to
IP 1.2.3.5 and fec0::2 into handle 1:3, all packets going to
IP 1.2.3.6 into handle 1:4, everything else into handle 1:1”
and obtaining that in enqueue exists, for example via nft and
passing that information in the skb, I’m all ear as well.
