IPv6 header information is not currently part of the entropy source for the 4-bit aggregation code used for LAG offload, even though it could be. The hardware reference manual says about these fields: ANA::AGGR_CFG.AC_IP6_TCPUDP_PORT_ENA Use IPv6 TCP/UDP port when calculating aggregation code. Configure identically for all ports. Recommended value is 1. ANA::AGGR_CFG.AC_IP6_FLOW_LBL_ENA Use IPv6 flow label when calculating AC. Configure identically for all ports. Recommended value is 1. Integration with the xmit_hash_policy of the bonding interface is TBD.
