Subject: Trying to run mptcp on my machine

Hi Guys,

I've been trying to get mptcp up and running on my machine (xubuntu
20.04) with little joy. What I did was install 5,8,5 kernel from here:

https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8.5/amd64/

Reboot, tried a curl:

curl http://www.multipath-tcp.org
Nay, Nay, Nay, your have an old computer that does not speak MPTCP.
Shame on you!

Checked this flag:

sudo cat /proc/sys/net/mptcp/enabled
1

Even tried to run this guy in the kernel repo with no joy
mptcp_connect.sh. Any pointers to get mptcp running? I couldn't find
too much documentation on how to configure it on GNU/Linux.
