[PATCH net-next v2 0/8] gve: Add Rx HW timestamping support

[Harshitha Ramamurthy <hramamurthy@google.com>]

From: Ziwei Xiao <ziweixiao@google.com>

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:
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)
