Previously, gve had been only initializing ptp aux work when hardware timestamping was initialized through ndo_hwtsatmp_set. As this patch series introduces XDP hardware timestamp metadata which will require the ptp aux work, the work can't be gated on the kernel_hwtstamp_config being set and must be initialized elsewhere. For simplicity, ptp_schedule_worker is invoked right after the ptp_clock is registered with the kernel (which happens during gve_probe or following reset). The worker is scheduled in GVE_NIC_TS_SYNC_INTERVAL_MS as the synchronous call to gve_clock_nic_ts_read makes the worker redundant if scheduled immediately. If gve cannot read the device clock immediately, it errors out of gve_init_clock.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
