This series collects Intel E810 iavf and ice driver enhancements developed for the Media Transport Library (MTL) to support high-performance SMPTE ST 2110 media streaming workflows.
The "new code" in this series (specifically the testpmd enhancement in patch 6) demonstrates how the standard DPDK buffer-split offload can be orchestrated with pinned external-buffer mempools (RTE_PKTMBUF_POOL_F_PINNED_EXT_BUF) to achieve this. By pinning mbufs to contiguous hugepages, the NIC DMAs RTP payloads directly into application- owned memory. This eliminates the need for the header-split. Documentation and a concrete configuration example for this workflow are included in the testpmd user guide (patch 6/6). The new 'create pinned-rxpool' command serves as both a test vehicle and a reference implementation for integrators. In this series: - iavf maximum ring descriptor count to raised 4096 (HW limit). - iavf queue rate limit enabled reconfiguration at runtime. - Added opt-in "rl_burst_size" ice devarg for tighter packet spacing (jitter reduction). - Enabled PTP timestamping for all packets on ice. - Added opt-in "no_runtime_queue_setup" iavf devarg to restore strict initialization semantics when required. - Dropped the ethdev and net/intel "header-split mbuf callback" API - Replaced the out-of-tree approach with a testpmd demonstration (patch 6) of the standard, upstream-preferred pinned-external-buffer workflow. - Fixed iavf error propagation and committed-state logic (Stephen Hemminger). - Converted the ice scheduler burst reduction and iavf runtime-config disabling into opt-in devargs to preserve default behavior. - Updated documentation, commit messages, and .mailmap.
