It is created only\nwhen vport metadata match and prio tag are enabled. But active-backup\nlag mode also uses it. It is independent of vport metadata match and\nprio tag. And vport metadata match can be disabled using the\nfollowing devlink command:\n\n # devlink dev param set pci/0000:08:00.0 name esw_port_metadata \\\n\tvalue false cmode runtime\n\nIf ingress acl is not created, will hit panic when creating drop rule\nfor active-backup lag mode. If always create it, there will be about\n5% performance degradation.\n\nFix it by creating ingress acl when needed. If esw_port_metadata is\ntrue, ingress acl exists, then create drop rule using existing\ningress acl. If esw_port_metadata is false, create ingress acl and\nthen create drop rule."
