It is not for me. It is a general question, if tc schould work with
the requested function general not with the kernel-line 4.14 (As
i was thinking that this should be come to a very long support.
(As i was suggest to read in an german page for computers; but
it may be a mistake from my side)
Or if the 4.14 series come to a "short end" and then it take no
matter when the function not work.
Best regards.
