====================
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.
