From: Ting Xu Date: Sat, 8 May 2021 07:11:47 +0000 (+0800) Subject: net/ice: fix IP RSS configuration template X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=664b8eb745b9b6249231cea2f2bc6ff4d4b6bc40;p=dpdk.git net/ice: fix IP RSS configuration template To enable IP fragment RSS hash, ICE_FLOW_SEG_HDR_IPV_FRAG is added to the IP RSS configuration template, together with ICE_FLOW_SEG_HDR_IPV_OTHER. It will cause error when associating flow profile. And packet id field for RSS is not correctly added when IP fragment is enabled. To fix this issue, this patch only selects one of the above two segment header types based on RSS types.
