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.

v3:
- Patch 1:
- Add PMD documentation and release notes entry.
- Move dynamic mbuf timestamp field registration to eth_dev_start().
- Replace 64-bit pointer casting with memcpy.
- Add devargs validation and support auto-base integer parsing.
- Patch 2:
- Add documentation and release notes entry.
- Add PTP file descriptor cleanup on device start, stop, and close.
- Return -errno on clock_gettime() failure and fix PTP open error logging.
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.
