[PATCH 0/6] net/gve: add hardware timestamping support

[mark-blasko <blasko@google.com>]

From: Mark Blasko <blasko@google.com>

This patch series introduces support for GVE hardware timestamping on DQO
queues. To support concurrent access, a mutex lock is introduced to protect
admin queue operations. A mechanism is then added to periodically synchronize
the NIC clock via AdminQ, and support is introduced for the read_clock ethdev
operation. Finally, the RX datapath is updated to reconstruct full 64-bit
timestamps from the 32-bit values in DQO descriptors.

Mark Blasko (6):
  net/gve: add thread safety to admin queue
  net/gve: add device option support for HW timestamps
  net/gve: add AdminQ command for NIC timestamps
  net/gve: add periodic NIC clock synchronization
  net/gve: support read clock ethdev op
  net/gve: reconstruct HW timestamps from DQO
