Why can't the entire data->tg be set to > zero when deleting it? I don't remember exactly but let me try: In case you have only one entry per row, then you could set the tg to have value 0. But in case you have 2 entries(use half keys), you need to set the tg to 0 only to the half entry that you delete. So for example if you have only 1 half entry at subword 1 then the tg should be 0xa0. Then when you add a new entry on the same row but at subword 0 then the tg should have the value 0xaa. The value 0xaa, comes from the fact that the type group for half entry is 0x2 and this needs to be set for each subword. And IS2 has 4 subwords therefore 0b10101010 = 0xaa. I hope this helps, if not I can look deeper in the code and see exactly. > Is there any special meaning to a TCAM entry > with subword zero unused? > > > + > > + data.type = IS2_ACTION_TYPE_NORMAL; > > + > > + VCAP_KEY_ANY_SET(PAG); > > + VCAP_KEY_SET(IGR_PORT_MASK, 0, ~BIT(ace->chip_port)); > > + VCAP_KEY_BIT_SET(FIRST, OCELOT_VCAP_BIT_1); > > + VCAP_KEY_BIT_SET(HOST_MATCH, OCELOT_VCAP_BIT_ANY); > > + VCAP_KEY_BIT_SET(L2_MC, ace->dmac_mc); > > + VCAP_KEY_BIT_SET(L2_BC, ace->dmac_bc); > > + VCAP_KEY_BIT_SET(VLAN_TAGGED, tag->tagged); > > + VCAP_KEY_SET(VID, tag->vid.value, tag->vid.mask); > > + VCAP_KEY_SET(PCP, tag->pcp.value[0], tag->pcp.mask[0]); > > + VCAP_KEY_BIT_SET(DEI, tag->dei); > > + > > + switch (ace->type) { > > + case OCELOT_ACE_TYPE_ETYPE: { > > + struct ocelot_ace_frame_etype *etype = &ace->frame.etype; > > + > > + type = IS2_TYPE_ETYPE; > > + VCAP_KEY_BYTES_SET(L2_DMAC, etype->dmac.value, > > + etype->dmac.mask); > > + VCAP_KEY_BYTES_SET(L2_SMAC, etype->smac.value, > > + etype->smac.mask); > > + VCAP_KEY_BYTES_SET(MAC_ETYPE_ETYPE, etype->etype.value, > > + etype->etype.mask); > > + VCAP_KEY_ANY_SET(MAC_ETYPE_L2_PAYLOAD); // Clear unused bits > > + vcap_key_bytes_set(&data, IS2_HKO_MAC_ETYPE_L2_PAYLOAD, > > + etype->data.value, etype->data.mask, 2); > > + break; > > + } > > + case OCELOT_ACE_TYPE_LLC: { > > + struct ocelot_ace_frame_llc *llc = &ace->frame.llc; > > + > > + type = IS2_TYPE_LLC; > > + VCAP_KEY_BYTES_SET(L2_DMAC, llc->dmac.value, llc->dmac.mask); > > + VCAP_KEY_BYTES_SET(L2_SMAC, llc->smac.value, llc->smac.mask); > > + for (i = 0; i < 4; i++) { > > + payload.value[i] = llc->llc.value[i]; > > + payload.mask[i] = llc->llc.mask[i]; > > + } > > + VCAP_KEY_BYTES_SET(MAC_LLC_L2_LLC, payload.value, payload.mask); > > + break; > > + } > > + case OCELOT_ACE_TYPE_SNAP: { > > + struct ocelot_ace_frame_snap *snap = &ace->frame.snap; > > + > > + type = IS2_TYPE_SNAP; > > + VCAP_KEY_BYTES_SET(L2_DMAC, snap->dmac.value, snap->dmac.mask); > > + VCAP_KEY_BYTES_SET(L2_SMAC, snap->smac.value, snap->smac.mask); > > + VCAP_KEY_BYTES_SET(MAC_SNAP_L2_SNAP, > > + ace->frame.snap.snap.value, > > + ace->frame.snap.snap.mask); > > + break; > > + } > > + case OCELOT_ACE_TYPE_ARP: { > > + struct ocelot_ace_frame_arp *arp = &ace->frame.arp; > > + > > + type = IS2_TYPE_ARP; > > + VCAP_KEY_BYTES_SET(MAC_ARP_L2_SMAC, arp->smac.value, > > + arp->smac.mask); > > + VCAP_KEY_BIT_SET(MAC_ARP_ARP_ADDR_SPACE_OK, arp->ethernet); > > + VCAP_KEY_BIT_SET(MAC_ARP_ARP_PROTO_SPACE_OK, arp->ip); > > + VCAP_KEY_BIT_SET(MAC_ARP_ARP_LEN_OK, arp->length); > > + VCAP_KEY_BIT_SET(MAC_ARP_ARP_TGT_MATCH, arp->dmac_match); > > + VCAP_KEY_BIT_SET(MAC_ARP_ARP_SENDER_MATCH, arp->smac_match); > > + VCAP_KEY_BIT_SET(MAC_ARP_ARP_OPCODE_UNKNOWN, arp->unknown); > > + > > + /* OPCODE is inverse, bit 0 is reply flag, bit 1 is RARP flag */ > > + val = ((arp->req == OCELOT_VCAP_BIT_0 ?
