[PATCH v2 0/2] net/af_xdp: add Rx timestamping and read_clock support

[Mark Blasko <blasko@google.com>]

This patch series introduces support for dynamic RX timestamping and
clock querying in the AF_XDP Poll Mode Driver.

The first patch introduces three new vdev devargs to specify
layout-agnostic metadata offsets and bitmasks for extracting hardware
RX timestamps from XDP metadata into the mbuf dynamic timestamp field.

The second patch implements the read_clock ethdev operation, querying
ethtool for the interface's PTP Hardware Clock index at start and using
clock_gettime to query the NIC hardware clock time.

v2:
- Patch 1:
  - Replace static metadata struct assumption with configurable vdev devargs
    for layout-agnostic timestamp offset extraction and validity verification.
- Patch 2:
  - New patch introduced in v2 to support read_clock ethdev operation.
