[PATCH v5 00/11] PCAP PMD improvements

[Stephen Hemminger]

This series improves the PCAP PMD with new features, better code quality,
and a comprehensive test suite.

Changes:
  - Update feature matrix to reflect actual capabilities
  - Replace unnecessary rte_malloc/rte_memcpy with standard libc
  - Fix multi-segment transmit handling (was using 9KB stack buffer)
  - Add MTU setting support for single interface mode
  - Convert integer flags to bool for type safety
  - Add VLAN strip (RX) and insert (TX) offload support
  - Support nanosecond timestamp precision
  - Localize global variables where possible
  - Remove unnecessary volatile from statistics
  - Add comprehensive unit test suite (18 test cases)
  - Add release notes

The VLAN and timestamp offloads follow the same patterns used by
virtio and af_packet PMDs.

The test suite covers basic TX/RX, varied packet sizes, jumbo frames,
infinite RX mode, statistics, MTU configuration, timestamps, multi-queue
operation, and VLAN offloads.

v5 - fix typo in features table
   - resolve minor checkpatch complaint
