[Mellanox]: unable to create ACL IPv6 table

[mkovnir]

Description

ACL_TABLE_L3V6 table on Mellanox switches cant be created due to unsupported ETHERTYPE field.

Steps to reproduce the issue:

1. Configure section ACL_TABLE with type "L3V6" and section ACL_RULE with one rule. Example: { "ACL_TABLE": { "port29-v6-in": { "policy_desc": "ingress v6 acl for port29", "type": "L3V6", "ports": ["Ethernet112"], "stage": "ingress" } }, "ACL_RULE": { "port29-v6-in|default": { "PRIORITY": "1", "SRC_IPV6": "0:0:0:0:0:0:0:0/0", "PACKET_ACTION": "DROP" } } }

2. Check logs from syncd and swss with keyword "ACL"

Describe the results you received: Syncd and swss reports errors about ACL_TABLE creation failure:

Describe the results you expected: ACL IPv6 table should be created and populated with rules, no SAI errors should be generated.

Mellanox team will review and provide a fix. Need to close the expected behaviour first and later on we will describe the solution.
