IGR_PORT_MASK

Ingress port mask.

IGR_PORT_MASK_SEL == 0:

Each bit in the mask correspond to physical ingress port.

IGR_PORT_MASK_SEL == 1:

Each bit in the mask correspond to the physical port which the frame was

looped on.

IGR_PORT_MASK_SEL == 2:

Each bit in the mask correspond to the masqueraded port.

If IGR_PORT_MASK_SEL == 3:

Bit 0: Physical src port == CPU0.

Bit 1: Physical src port == CPU1.

Bit 2: Physical src port == VD0.

Bit 3: Physical src port == VD1.

Bits 4:9: Src port (possibly masqueraded).

Bits 44:48: ifh.misc.pipeline_pt.

Bits 49:51: ifh.misc.pipeline_act.

Bits 52: Reserved.

L2_MC

Set if frame’s destination MAC address is a multicast address (bit 40 = 1). 1

L2_BC

Set if frame’s destination MAC address is the broadcast address (FF-FF-

FF-FF-FF-FF).

TPID0

Tag protocol identifier of the frame’s first tag (outer tag):

0: Untagged.

1: 0x8100.

4: 0x88A8.

5: Custom value 1.

6: Custom value 2.

7: Custom value 3.

PCP0

By default PCP from frame but it is selectable per lookup in VCAP CLM

whether to use the current classified PCP instead

(ANA_CL::ADV_CL_CFG.USE_CL_TCI0_ENA).

DEI0

By default DEI from frame but it is selectable per lookup in VCAP CLM

whether to use the current classified DEI instead

(ANA_CL::ADV_CL_CFG.USE_CL_TCI0_ENA).

VID0

By default VID from frame but it is selectable per lookup in VCAP CLM

whether to use the current classified VID instead

(ANA_CL::ADV_CL_CFG.USE_CL_TCI0_ENA).

For untagged frames, VID0 is set to 0.
