[PATCH v3 00/51] 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 (Wuxi Stars Micro System) Ethernet
driver, including the common driver (drivers/common/sxe2), the net
driver (drivers/net/sxe2), and its documentation.

The driver supports:
- Legacy and switchdev modes with VF representors
- Scalar and vectorized (SSE/AVX2/AVX512/NEON) Rx/Tx paths
- FNAV and ACL flow engines with per-flow statistics
- RSS, QinQ, IPsec, Traffic Management and multi-process support

In addition to the driver functionality, the series fixes a number of
correctness issues found during review, including a security context
leak in the device init error path, a NULL dereference in the
vectorized Tx mbuf release path, an out-of-bounds representor ID
access, and a representor LSC loop counter type mismatch. The command
channel log messages and ioctl channel handling are also aligned with
the reference implementation.

This is v3 of the series, incorporating review feedback. All patches
build independently and no ABI changes are introduced.
