====================
net: prepare pacing offload support

Some network devices have the ability to offload EDT (Earliest
Departure Time) which is the model used for TCP pacing and FQ
packet scheduler.

Some of them implement the timing wheel mechanism described in
https://saeed.github.io/files/carousel-sigcomm17.pdf
with an associated 'timing wheel horizon'.

In order to upstream the NIC support, this series adds :

1) timing wheel horizon as a per-device attribute.

2) FQ packet scheduler support, to let paced packets
   below the timing wheel horizon be handled by the driver.
