Right now we don't have COPP removal logic. Could you help add the corresponding unit tests? |

The unit tests have committed, please take a review. To test the removal logic, #1038 must be merged. Or the copporch will trap into endless loop. |

What I did
Removing the trap ids first when removing the copp group table entry.
Why I did it
When the copporch received a DEL event from redis DB, it just recreate the trap id with defaul attribute.The creation operation fails because that it already exists.
If the copp group table was removed, the trap ids which associated with the table group should delete too, no just recreate them with default attribute.
How I verified it
root@48S-sdd:/etc/swss/config.d# cat 00-copp.config_add.json
[
{
"COPP_TABLE:trap.group.arp": {
"trap_ids": "arp_req,arp_resp,neigh_discovery",
"trap_action":"copy",
"trap_priority":"4",
"queue": "4",
"meter_type":"packets",
"mode":"tr_tcm",
"cir":"600",
"cbs":"600",
"pir":"600",
"pbs":"600",
"red_action":"drop"
},
"OP": "SET"
}
]
root@48S-sdd:/etc/swss/config.d# cat 00-copp.config_del.json
[
{
"COPP_TABLE:trap.group.arp": {
"trap_ids": "arp_req,arp_resp,neigh_discovery",
"trap_action":"copy",
"trap_priority":"4",
"queue": "4",
"meter_type":"packets",

},

}
]
When i load the delection configuration, it throws out error as follows:
