Subject: [PATCH v2 net-next 05/14] net: mscc: ocelot: use ipv6 in the aggregation code
Date: Sat, 16 Jan 2021 02:59:34 +0200 [thread overview]
Message-ID: <20210116005943.219479-6-olteanv@gmail.com> (raw)
In-Reply-To: <20210116005943.219479-1-olteanv@gmail.com>
From: Vladimir Oltean <vladimir.oltean@nxp.com>
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.
