The series is to add timestamping support for Meta's NIC driver.

Changelog:
v3 -> v4:
- use adjust_by_scaled_ppm() instead of open coding it
- adjust cached value of high bits of timestamp to be sure it
  is older then incoming timestamps
v2 -> v3:
- rebase on top of net-next
- add doc to describe retur value of fbnic_ts40_to_ns()
v1 -> v2:
- adjust comment about using u64 stats locking primitive
- fix typo in the first patch
- Cc Richard
