[PATCH v4 0/5] Intel network drivers enhancements

[Dawid Wesierski]

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.

Dawid Wesierski (5):
  net/iavf: increase max ring descriptors to hardware limit
  net/iavf: allow runtime queue rate limit configuration
  net/ice: add scheduler rate-limiter burst size devarg
  net/iavf: disable runtime queue setup capability
  app/testpmd: add pinned external-buffer Rx pool command
