works on centos8, doesn't work on centos7

Describe the issue
as title, it seems that go-tc works on centos8, doesn't work on centos7.
does go-tc has supported kernel version lists doc? i can't not find in repo.

Expected behavior
i would expect the tc-lib will recognize the different kernel verion to be compatible with them

Minimal code example to reproduce the issue
on centos 7, build the example and run will get the error report
could not get qdiscs: extractTCAOptions(): unsupported kind pfifo_fast: unknown kind

Hi!
Not every qdisc/class or filter is available for every kernel. Can you name the kernel version that is used in CentOS 7? And did you check if this kernel version supports pfifo_fast?
Another option is, that you use different versions of this package. pfifo_fast was added with commit d134361. So you need a more recent version of this package than v0.3.0.
