[PATCH v2 13/13] doc/sxe2: add acl-stat-type parameter documentation

From: Jie Liu <[email protected]>

This commit adds documentation for the acl-stat-type parameter
which controls ACL statistics type used for ACL rule hit counting.

- 1: Only count the number of packets
- 2: Only count the number of bytes
- 3: Count both packets and bytes (default)

-- ``drv-sw-stats`` parameter [int]
-
-  This parameter controls whether per-packet software statistics (SW stats)
-  are collected in the Rx data path.
-
-  Hardware packet statistic counters may be inaccurate for certain packet types
-  due to hardware design limitations.
-  When accuracy of Rx packet classification statistics is critical,
-  enabling this parameter allows the driver to accumulate statistics in software
-  as packets are received, providing an alternative statistical path
-  that bypasses hardware counter inaccuracies.

-  - 0: Disable software statistics collection (default).
-    The basic port statistics (``ipackets``, ``ibytes``) are reported
-    from the hardware counters.
-  - 1: Enable software statistics collection.
-    Per-packet software statistics are accumulated for unicast,
-    multicast, broadcast, and dropped packets in the Rx data path.
-
-  When enabled, the following extended statistics (xstats) are available:
-  ``rx_sw_unicast_packets``, ``rx_sw_multicast_packets``,
-  ``rx_sw_broadcast_packets``, ``rx_sw_drop_packets``,
-  and ``rx_sw_drop_bytes``.
