Subject: [PATCH net-next 00/12] sfc: support PTP on 8000 and X2000 series NICs

Starting from the 8000-series (Medford 1), SFC NICs can timestamp TX packets
 sent through an ordinary DMA queue, rather than a special control-plane
 operation as in the 7000-series.  Patches 2-8 implement support for this.
The X2000-series (Medford 2) changes the format of timestamps, from seconds+
 (2^27)ths to seconds + quarter nanoseconds, as well as changing the shift
 of the frequency adjustment for increased precision.  Patches 9-12
 implement support for these changes.
Patch #1 is an unrelated fix for NAPI budget handling, needed in order for
 TX completion changes in the later patches to apply cleanly.

Bert Kenward (1):
  sfc: remove tx and MCDI handling from NAPI budget consideration

Edward Cree (2):
  sfc: on 8000 series use TX queues for TX timestamps
  sfc: support second + quarter ns time format for receive datapath

Laurence Evans (3):
  sfc: simplify RX datapath timestamping
  sfc: support separate PTP and general timestamping
  sfc: support Medford2 frequency adjustment format

Martin Habets (6):
  sfc: handle TX timestamps in the normal data path
  sfc: add function to determine which TX timestamping method to use
  sfc: use main datapath for HW timestamps if available
  sfc: only enable TX timestamping if the adapter is licensed for it
  sfc: MAC TX timestamp handling on the 8000 series
  sfc: only advertise TX timestamping if we have the license for it
