First round of EDT patches left TCP stack in a non optimal state. - High speed flows suffered from loss of performance, addressed by the first patch of this series.
- Second patch brings pacing to the current state of networking, since we now reach ~100 Gbit on a single TCP flow. - Third patch implements a mitigation for scheduling delays, like the one we did in sch_fq in the past. - Fourth patch removes one special case in sch_fq for ACK packets. - Fifth patch removes a serious perfomance cost for TCP internal pacing. We should setup the high resolution timer only if really needed. - Sixth patch fixes a typo in BBR. - Last patch is one minor change in cdg congestion control. Neal Cardwell also has a patch series fixing BBR after EDT adoption.
