tc lacks Cake qdisc in 18.04 + HWE 5.4 kernel

[Stephen Hill]

I am using the 5.4 HWE kernel in 18.04, and even though this kernel has the CAKE qdisc, I am unable to use it as the version of tc, which is used to configure it, is too old. Even the backported tc is too old.
Can we get the 20.04 iproute2 package, which does support the CAKE qdisc, backported to 18.04 to fix this?

P.S. I did try pulling iproute2 directly from 20.04 repos using apt pinning, but then had glibc version incomptibility problems.
