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. v4: - Rebase on current main - Add VLAN strip - Add release note - better multi-segment handling Stephen Hemminger (11): doc: update features for PCAP PMD net/pcap: avoid using rte_malloc and rte_memcpy net/pcap: cleanup transmit of multi segment net/pcap: support setting MTU net/pcap: use bool for flags net/pcap: support VLAN offloads net/pcap: support nanosecond timestamp precision net/pcap: remove global variables net/pcap: avoid use of volatile test: add test for pcap PMD net/pcap: add release note app/test/meson.build | 2 + app/test/test_pmd_pcap.c | 2263 ++++++++++++++++++++++++ doc/guides/nics/features/pcap.ini | 10 + doc/guides/rel_notes/release_26_03.rst | 7 + drivers/net/pcap/pcap_ethdev.c | 376 ++-- drivers/net/pcap/pcap_osdep.h | 1 + drivers/net/pcap/pcap_osdep_freebsd.c | 37 +- drivers/net/pcap/pcap_osdep_linux.c | 21 + drivers/net/pcap/pcap_osdep_windows.c | 6 + 9 files changed, 2586 insertions(+), 137 deletions(-) create mode 100644 app/test/test_pmd_pcap.c -- 2.51.0
