[PATCH v4 00/27] net/hinic3: add PMD features and fixes

[Jiacheng Ye <yejiacheng4@h-partners.com>]

This series fixes offload capability advertisement, cmdq/compact CQE
configuration, and several defects found during review, and adds NIC
type identification, FEC, CIR drop statistics, VF LAG/link state, COS
mask/map, mbox recording, RSS hash configuration, compact CQE Rx/Tx
paths, TSO segment expansion, Tx burst mode reporting, queue statistics,
pseudo-header checksum, per-tile cmdq ops, SP560 NIC support, and device
kvargs tunables.

v4:
- Move the queue depth and state consistency patch ahead of the TSO
  expansion, so the copy pool is sized from a queue depth that is
  already validated, and keep resetting the cached depth in
  dev_configure().
- Validate the queue depth range before caching it as the first queue
  depth, so an out-of-range nb_desc cannot poison the saved depth and
  make a later valid setup fail the equality check.
- Reorder the series so the pseudo-header checksum fix follows the NIC
  type identification patch it depends on, repairing the bisect break
  in the later Tx/TSO patches.
- Size the TSO copy pool from the cached Tx queue depth and cap each
  queue at 256 mbufs, and start each segment copy at the remaining
  length via rte_pktmbuf_mtod_offset() so a segment spanning several
  copy mbufs is not copied twice.
- Keep the copy mbuf chain consistent: update nb_segs and pkt_len while
  the chain is built, and clear pkt_len on each newly allocated copy
  mbuf rather than on the original one.
- Drop the segment-count check from the transmit path together with the
  HINIC3_TSO_SEG_NUM_INVALID macro: 255 is the WQE buffer descriptor
  limit, not an input segment limit, and segments beyond the non-copy
  window are already compressed into copy mbufs.
- Reject TSO packets whose tso_segsz is zero instead of dividing by it.
- Fix the pseudo-header L4 protocol selection: pass IPPROTO_UDP or
  IPPROTO_TCP directly at each call site instead of testing the TCP
  offload bit, which also matched UDP packets because the UDP flag
  value shares that bit, and use rte_cpu_to_be_32() so the IPv6
  next-header value is placed correctly regardless of host endianness.
- Drop the IPv6 extension-header walk from the pseudo-header
  calculation as requested in review: rte_net_get_ptype() already
  accounts for the extension headers in mbuf->l3_len, so the walk was
  redundant.
- Split the SP230 Rx MSI-X masking out of the interrupt setup so
  dev_start keeps working on igb_uio/uio_pci_generic when Rx interrupts
  are disabled, and advertise full Rx interrupt support in hinic3.ini.
- Validate the VXLAN-GPE mask the same way as GENEVE, rejecting rules
  that match the flags, reserved bits or the next-protocol field, which
  cannot be programmed into the TCAM.
- Validate device kvargs against the accepted key list and parse their
  integer values in base 10, so a leading zero is not taken as an octal
  prefix.
- Program the TX completion index coalescing parameters into the SQ
  context tables: they were accepted as device arguments but the driver
  still programmed the built-in constants.
- Introduce rx_cqe_compact_en in the compact CQE Rx patch rather than in
  the kvargs patch, so every patch that accepts a parameter also makes
  it take effect.
- Remove unused Rx CQE packet-type enumerators, fix the DEAULT/DEFAULT
  typo, drop a duplicated "failed" in two log messages, use { 0 } for
  zero initialization, split over-long lines and repair alignment
  warnings reported by checkpatch.

v3:
- Move the ethertype-flow TCAM index leak fix out of the flow-refactor
  patch into its own patch with a Fixes tag and a stable Cc tag.
- Set burst function pointers and tx_pkt_prepare for both primary and
  secondary processes, and select the Tx path on its own feature bit.
- Zero the RQ/SQ context buffers and honour dp_intr_en for the STN CEQ
  attribute in compact CQE mode.
- Return the number of Tx packets consumed instead of the doorbell
  count, and guard the Tx prefetch against overreading the array.
- Validate device kvargs and reject values above the hardware field
  width; document the real defaults and units.
- Reject mismatched queue depths and reset saved depths in
  dev_configure(), and size the TSO copy pool per port.
- Report FEC capabilities per supported speed regardless of link state.
- Route the private dump through fprintf() on the provided FILE*.
- Derive the pseudo-header L4 protocol from the offload flags and fail
  shared or indirect mbufs; add Fixes and stable Cc tags.
- Drop stable Cc tags where the Fixes target is not in an LTS release
  and remove dead code and unused definitions.

v2:
- Add five bug fixes (SP230 VF PCI device ID, ethertype flow double
  removal, VXLAN VNI spec/mask, vport enable null dereference, and
  secondary-process ethdev ops setup).
- Split NIC type identification into its own patch and drop the mbox
  count telemetry patch.
- Add hinic3.rst and features/hinic3.ini documentation.
- Drop the tx_free_loop and rx_empty_threshold devargs and the Tx/Rx
  spin loops.
- Use the correct GENEVE/VXLAN-GPE flow item types and reject
  unsupported mask fields; reject IP-in-IP rules on SP620.
- Remove QINQ offload advertisement, split link_status and
  vf_valid_status into separate variables, use memcpy for unaligned mbox
  reads, and drop module parameter reads.
- Split the Tx burst patch into focused, self-contained commits for
  queue depth/state consistency, SP230 VF software statistics, Tx burst
  mode reporting, and Tx queue copied-mbuf statistics.
- Reword commit messages with full Fixes hashes and add
  stable@dpdk.org Cc tags where the defect exists in a released version.
