[PATCH net-next v4 0/8] gve: Add Rx HW timestamping support

[Harshitha Ramamurthy]

From: Ziwei Xiao <ziweixiao@xxxxxxxxxx>

This patch series add the support of Rx HW timestamping, which sends
adminq commands periodically to the device for clock synchronization with
the nic.

Changes:
v4:
  - release the ptp in the error path of gve_init_clock (Jakub Kicinski)
  - add two more reserved fields in gve_nic_ts_report, anticipating
    upcoming use, to align size expectations with the device from the
    start (team internal review, Shachar Raindel)
v3:
  - change the last_read to be u64 on patch 6/8 (Vadim Fedorenko)
  - update the title and commit message of patch 7/8 to show it's adding
    support for ndo functions instead of ioctls (Jakub Kicinski)
  - Utilize extack for error logging instead of dev_err (Jakub Kicinski)
v2:
  - add initial PTP device support to utilize the ptp's aux_work to
    schedule sending adminq commands periodically (Jakub Kicinski,
    Vadim Fedorenko)
  - add adminq lock patch into this patch series instead of sending out
    to net since it's only needed to resolve the conflicts between the
    upcoming PTP aux_work and the queue creation/destruction adminq
    commands (Jakub Kicinski)
  - add the missing READ_ONCE (Joe Damato)
