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.
