[PATCH v6 00/13] net/pcap: improvements and new features

[Stephen Hemminger]

This series modernizes the PCAP PMD with bug fixes, code cleanup,
and new features.

**New features:**
- VLAN insert and strip offload support
- Nanosecond timestamp precision (using pcap_create/pcap_activate API)
- MTU configuration in single interface mode
- Advertise multi-segment TX capability

**Bug fixes:**
- Transmit now always consumes all packets, counting failures as errors
  rather than returning early (matches other PMD behavior)
- Remove silent truncation of oversized multi-segment packets
- Replace large stack buffers with dynamic allocation

**Code cleanup:**
- Add explicit header includes
- Remove unnecessary casts and rte_malloc/rte_memcpy usage
- Consolidate boolean flag parsing with input validation
- Reduce scope of file-level variables
- Replace volatile with proper atomics

**Other:**
- Update feature matrix documentation
- Add comprehensive unit test suite
- Take on maintainership

v6:
- Add maintainers patch
- Add patches for explicit header includes and removing unnecessary casts
- Fold release notes into individual patches
- Improve commit message subjects for clarity
