From: Lance Richardson Date: Fri, 26 Mar 2021 16:37:32 +0000 (-0400) Subject: app/test: fix IPv6 header initialization X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a906371d2758df7260640873d93f888724759448;p=dpdk.git app/test: fix IPv6 header initialization Fix two issues found when writing PMD unit tests for HW ptype and L4 checksum offload: - The version field in the IPv6 header was being set to zero, which prevented hardware from recognizing it as IPv6. The IP version field is now set to six. - The payload_len field was being initialized using host byte order, which (among other things) resulted in incorrect L4 checksum computation. The payload_len field is now set using network (big-endian) byte order.
