Dave Taht 2db6dc2662 sch_cake: Make gso-splitting configurable from userspace ... This patch restores cake's deployed behavior at line rate to always split gso, and makes gso splitting configurable from userspace. running cake unlimited (unshaped) at 1gigE, local traffic: no-split-gso bql limit: 131966 split-gso bql limit: ~42392-45420 On this 4 stream test splitting gso apart results in halving the observed interpacket latency at no loss in throughput.
