> This reverts commit 15692396fd68932b6a81f00f12d4b0da12baa7d3
> (eal/ppc64: implement arch-specific TSC freq query). We intended to derive
> pkt/sec estimation with cpu clock frequency. As timebase register serves
the
> timer purpose, we need to stick with it for calculating pkt/sec, hence
reverting
> the change.
