Subject: [PATCH mlx5-next 0/2] Improvements for PTP clock in mlx5 driver

This is a pair of patches for the mlx5 driver related to the PTP clock.

The first patch fixes a potential issue causing backward jumps due to a
late update of the PHC timecounter.

The second patch adds support for the PTP_SYS_OFFSET_EXTENDED ioctl.

Miroslav Lichvar (2):
  mlx5: update timecounter at least twice per counter overflow
  mlx5: extend PTP gettime function to read system clock
