[Cake] centos 8 and cake and flent

Currently centos (and I assume redhat) is at 4.18. Cake went into 4.19
so I assume the next major
redhat/centos releases will have it.

Is there a yum/rpm expert in the house? flent does not appear to be
packaged up for this (?),
neither is netperf or irtt. Is there a repo I could use?

tc is not supplied by default apparently but I was relieved to see
once I built iproute head that
fq_codel was indeed the default scheduler for centos. But jeeze, tc is
not supplied by default in centos?

Anyway, with at least this much I got most of our tools running.

yum update
yum install golang git automake make bison flex libmnl-devel python3
kernel-modules-extra kernel-devel libelf-devel

pip3 install flent
built irtt from github

Can't find pandoc either.

And my attempt to build cake out of tree did this:

./tc qdisc add dev eth0 root cake bandwidth 1gbit
Error: NLA_F_NESTED is missing.

I guess I should try building the 4.18 version of iproute2... but I'm
going back to bed.

I'm also getting pretty weird flent results from linode's cloud
nowadays, this server went under ssh attack
immediately among other things,
