This patch series converts netem away from the old "ticks" interface and
userspace API, and adds support for a new "slot" feature intended to
emulate bursty macs such as WiFi and LTE better.

Changes since v2:
Use u64 for packet_len_sched_time()
Use simpler max(time_to_send,q->slot.slot_next)

Changes since v1:
Always pass new nanosecond APIs to userspace

Dave Taht (3):
  netem: convert to qdisc_watchdog_schedule_ns
  netem: add uapi to express delay and jitter in nanoseconds
  netem: support delivering packets in delayed time slots
