Willem added GSO support to UDP stack, greatly improving performance of QUIC servers.
We also want to enable in-kernel pacing, which is possible thanks to EDT model, since each sendmsg() can provide a timestamp for the skbs. We have to change sch_fq to enable feeding packets in arbitrary EDT order, and make sure that packet classification do not trust unconnected sockets. Note that this patch series also is a prereq for a future TCP change enabling per-flow delays/reorders/losses to implement high performance TCP emulators.
