This isn=E2=80=99t the same test or kernel, but I don=E2=80=99t see a = problem running 128 flows *generated by* the APU2 with fq_codel or Cake = at line rate with kernel 4.9.110-1. Of course, when it=E2=80=99s = actually generating the traffic, it=E2=80=99s out of CPU at these = speeds. I=E2=80=99ll see if I can do a pure routing test later at the = lab, to at least exonerate 4.9=E2=80=A6
