From: Lijun Ou Date: Wed, 21 Oct 2020 08:54:43 +0000 (+0800) Subject: net/hns3: enable RSS for IPv6-SCTP dst/src port fields X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=1bc633c3400851a7244f6608e05d37068a78cd5c;p=dpdk.git net/hns3: enable RSS for IPv6-SCTP dst/src port fields For Kunpeng930 NIC hardware, it supports to use dst/src port to RSS hash for ipv6-sctp packet type. However, the Kunpeng920 NIC hardware is different with it. The Kunpeng920 NIC only supports dst/src ip to RSS hash for ipv6-sctp packet type.
