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 header/payload split use case is served by the standard DPDK buffer-split offload combined with pinned external-buffer mempools (RTE_PKTMBUF_POOL_F_PINNED_EXT_BUF): by pinning mbufs to contiguous hugepages, the NIC DMAs RTP payloads directly into application-owned memory. A concrete configuration example and the 'create pinned-rxpool' testpmd command that serves as a reference implementation are documented in the testpmd user guide (patch 5/5). In this series: - iavf maximum ring descriptor count raised to the E810 hardware limit. - iavf queue rate limit reconfiguration allowed at runtime. - Added opt-in "rl_burst_size" ice devarg for tighter packet spacing (jitter reduction). - Added opt-in "no_runtime_queue_setup" iavf devarg to restore strict initialization semantics when required. v3 -> v4: - Dropped the ice PTP documentation patch entirely. Applications that need a hardware Rx timestamp on all traffic (not just IEEE 1588 packets) already have RTE_ETH_RX_OFFLOAD_TIMESTAMP available today; this is an existing, generic offload and does not need a dedicated patch to point it out. The datapath change that misidentified regular traffic as PTP (flagged by Bruce Richardson) is also dropped with it. - Set the whole series author to Dawid Wesierski. - Rebased onto latest main. v2 -> v3: - Dropped the ethdev and net/intel "header-split mbuf callback" API in favour of the upstream-preferred pinned-external-buffer workflow, now demonstrated in testpmd (patch 5). - 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 behaviour. - Updated documentation, commit messages, and .mailmap.
