+Subject: [PATCH] datapath: Add net/ip6_checksum.h to stt.c
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+`csum_ipv6_magic` is an asm inline on most platforms. However if it is
+not defined (like on ppc64le) including <net/ip6_checksum.h> will fall
+back to the c implementation by wrapping it in an
+`#ifndef _HAVE_ARCH_IPV6_CSUM`.
