[net-next,0/5,pull,request] 1GbE Intel Wired LAN Driver Updates 2020-01-06

This series contains updates to igc to add basic support for
timestamping.

Vinicius adds basic support for timestamping and enables ptp4l/phc2sys
to work with i225 devices.  Initially, adds the ability to read and
adjust the PHC clock.  Patches 2 & 3 enable and retrieve hardware
timestamps.  Patch 4 implements the ethtool ioctl that ptp4l uses to
check what timestamping methods are supported.  Lastly, added support to
do timestamping using the "Start of Packet" signal from the PHY, which
is now supported in i225 devices.

While i225 does support multiple PTP domains, with multiple timestamping
registers, we currently only support one PTP domain and use only one of
the timestamping registers for implementation purposes.

The following are changes since commit df2c2ba831a04083ad7485684896eeb090ca3c7d:
  Merge branch 'Convert-Felix-DSA-switch-to-PHYLINK'
and are available in the git repository at:
