net: microchip: sparx5: Adding KUNIT test for the VCAP API

Browse Source 
This provides a KUNIT test suite for the VCAP APIs encoding functionality.

The test can be run by adding these settings in a .kunitconfig file

CONFIG_KUNIT=y
CONFIG_NET=y
CONFIG_VCAP_KUNIT_TEST=y

* VCAP_AF_CPU_QUEUE_NUM: W3, sparx5: is2/es2
* CPU queue number. Used when CPU_COPY_ENA is set.
* VCAP_AF_DEI_ENA: W1, sparx5: is0
* If set, use DEI_VAL as classified DEI value. Otherwise, DEI from basic
* classification is used
* VCAP_AF_DEI_VAL: W1, sparx5: is0
* See DEI_ENA
* VCAP_AF_DP_ENA: W1, sparx5: is0
* If set, use DP_VAL as classified drop precedence level. Otherwise, drop

* Forward selector: 0: Forward. 1: Discard. 2: Redirect. 3: Copy.
* VCAP_AF_HIT_ME_ONCE: W1, sparx5: is2/es2
* Setting this bit to 1 causes the first frame that hits this action where the
* HIT_CNT counter is zero to be copied to the CPU extraction queue specified in
* CPU_QUEUE_NUM. The HIT_CNT counter is then incremented and any frames that
* hit this action later are not copied to the CPU. To re-enable the HIT_ME_ONCE
* functionality, the HIT_CNT counter must be cleared.
* VCAP_AF_IGNORE_PIPELINE_CTRL: W1, sparx5: is2/es2
* Ignore ingress pipeline control. This enforces the use of the VCAP IS2 action
* even when the pipeline control has terminated the frame before VCAP IS2.
* VCAP_AF_INTR_ENA: W1, sparx5: is2/es2
* If set, an interrupt is triggered when this rule is hit
* VCAP_AF_ISDX_ADD_REPLACE_SEL: W1, sparx5: is0
* Controls the classified ISDX. 0: New ISDX = old ISDX + ISDX_VAL. 1: New ISDX

* Index for QoS mapping table lookup
* VCAP_AF_MAP_KEY: W3, sparx5: is0
* Key type for QoS mapping table lookup. 0: DEI0, PCP0 (outer tag). 1: DEI1,
* PCP1 (middle tag). 2: DEI2, PCP2 (inner tag). 3: MPLS TC. 4: PCP0 (outer
* tag). 5: E-DEI, E-PCP (E-TAG). 6: DSCP if available, otherwise none. 7: DSCP
* if available, otherwise DEI0, PCP0 (outer tag) if available using MAP_IDX+8,
* otherwise none
* VCAP_AF_MAP_LOOKUP_SEL: W2, sparx5: is0
* Selects which of the two QoS Mapping Table lookups that MAP_KEY and MAP_IDX
* are applied to. 0: No changes to the QoS Mapping Table lookup. 1: Update key
* type and index for QoS Mapping Table lookup #0. 2: Update key type and index
* for QoS Mapping Table lookup #1. 3: Reserved.
* VCAP_AF_MASK_MODE: W3, sparx5: is0/is2
* Controls the PORT_MASK use. Sparx5: 0: OR_DSTMASK, 1: AND_VLANMASK, 2:

* MASK_MODE.
* VCAP_AF_MATCH_ID: W16, sparx5: is0/is2

* if the frame is forwarded to the CPU (CPU_COPY_ENA). The result is placed in
* IFH.CL_RSLT.
* VCAP_AF_MATCH_ID_MASK: W16, sparx5: is0/is2
* Mask used by MATCH_ID.
* VCAP_AF_MIRROR_PROBE: W2, sparx5: is2
* Mirroring performed according to configuration of a mirror probe. 0: No
* mirroring. 1: Mirror probe 0. 2: Mirror probe 1. 3: Mirror probe 2
* VCAP_AF_MIRROR_PROBE_ID: W2, sparx5: 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.
* VCAP_AF_NXT_IDX: W12, sparx5: is0
* Index used as part of key (field G_IDX) in the next lookup.
* VCAP_AF_NXT_IDX_CTRL: W3, sparx5: is0
* Controls the generation of the G_IDX used in the VCAP CLM next lookup
* VCAP_AF_PAG_OVERRIDE_MASK: W8, sparx5: is0
* Bits set in this mask will override PAG_VAL from port profile. New PAG =
* (PAG (input) AND ~PAG_OVERRIDE_MASK) OR (PAG_VAL AND PAG_OVERRIDE_MASK)
* VCAP_AF_PAG_VAL: W8, sparx5: is0
* See PAG_OVERRIDE_MASK.

* VCAP_AF_PIPELINE_PT: W5, sparx5: is0/is2
* Pipeline point used if PIPELINE_FORCE_ENA is set
* VCAP_AF_POLICE_ENA: W1, sparx5: is2/es2

* ACL policer specified in POLICE_IDX. Only applies to the first lookup.
* VCAP_AF_POLICE_IDX: W6, sparx5: is2/es2
* Selects VCAP policer used when policing frames (POLICE_ENA)
* VCAP_AF_POLICE_REMARK: W1, sparx5: es2
* If set, frames exceeding policer rates are marked as yellow but not
* discarded.
* VCAP_AF_PORT_MASK: sparx5 is0 W65, sparx5 is2 W68
* Port mask applied to the forwarding decision based on MASK_MODE.
* VCAP_AF_QOS_ENA: W1, sparx5: is0
