Multipath tcp (mptcp) is now part of the official linux kernel. The
official kernel still lacks features compared to this out of tree ones
but considering the userbase, I dont see any compelling reason.
I keep using that kernel and those utilities so they will stay packaged
at https://github.com/teto/mptcp-flake where they wont annoy the whole
nixpkgs crowd that doesn't care about it.
