[PATCH v5 00/45] net/sxe2: add Stars SXE2 net driver with fixes

[liujie5 at linkdatatechnology.com]

From: Jie Liu <liujie5 at linkdatatechnology.com>

This series adds the Stars SXE2 network driver together with a set of
fixes accumulated while validating the driver against the historical
kernel implementation and reviewing the code.

This is the v5 revision. Changes since v4 address the community review
of the v4 series:

- Drop the ineffective IPsec key length check in
  sxe2_security_valid_key() (the same limit is already enforced at the
  top of the function) and keep only the security context pointer
  cleanup, which is now its own commit.
- Make the QinQ and RSS offload capability gating actually effective:
  RTE_ETH_TX_OFFLOAD_QINQ_INSERT is removed from the unconditional
  capability list and only advertised when no port VLAN is configured;
  RTE_ETH_RX_OFFLOAD_RSS_HASH is advertised only when the RSS offload
  capability flag is set.
- Fix switchdev representor matching so the common devarg forms
  (e.g. "representor=vf0", bare-number form) that leave nb_ports == 0
  are treated as "no PF constraint" instead of being rejected.
- Fix the representor VSI teardown: sxe2_vsi_destroy() now unlinks
  SXE2_VSI_T_DPDK_ESW nodes from other_vsi_list before freeing them.
- Restore a scalar Tx fallback on arm64 when NEON is not available so
  tx_pkt_burst is always installed.
- Add the same PF-only guard to the UDP tunnel port delete and clear
  paths that add already has.
- Move sxe2_link_update() out of the command-channel link status query
  into the two callers, keeping the command layer free of ethdev side
  effects and avoiding the dev_data dereference.
- Evaluate the adapter argument exactly once in the command params fill
  macro.
- Remove ineffective nb_rx_queues/nb_tx_queues assignments from device
  info (ethdev overwrites them after the PMD callback) and from the
  representor device info (new commit with a Fixes: tag).
- Fix the ioctl mmap debug log labels and reword the commit messages
  for the security context, command fill macro and command struct
  alignment commits.

Patch 30/44 of the v4 series still bundles unrelated NEON Rx data path
changes into the vectorized Tx commit, and patches 21/22 still leave
the dev_close and dev_init teardown orders slightly different; these
are left for a follow-up.
