+ * VCAP_AF_CNT_ID: sparx5 is2 W12, sparx5 es2 W11
+ * Counter ID, used per lookup to index the 4K frame counters (ANA_ACL:CNT_TBL).

+ * VCAP_AF_HIT_ME_ONCE: W1, sparx5: is2/es2
+ * Setting this bit to 1 causes the first frame that hits this action where the

+ * functionality, the HIT_CNT counter must be cleared.
+ * VCAP_AF_IGNORE_PIPELINE_CTRL: W1, sparx5: is2/es2

+ * Signals a mirror probe to be placed in the IFH. Only possible when FWD_MODE
+ * is copy. 0: No mirroring. 1–3: Use mirror probe 0-2.
