From: Wenjun Wu Date: Tue, 17 Aug 2021 06:49:55 +0000 (+0800) Subject: net/iavf: fix flow director L3 field for IPv4 fragments X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8cd9b090b46056e15aa3b533cb94c0f1b9ecad79;p=dpdk.git net/iavf: fix flow director L3 field for IPv4 fragments Originally, the value of field_selector for IPV4_FRAG header hdr1 is the same as the previous header hdr2. For IPv4 packets, field_selector for hdr2 can be any value between 0 and 4, depending on the selected field. Actually, this value for IPV4_FRAG should be constant 0, which denotes the field packet ID. This patch adds an assignment to hdr1->field_selector to make sure that it is always 0.
