Subject: linux-next: build failure after merge of the final tree
 (netnext-tree related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

net/core/pktgen.c: In function 'fill_packet_ipv6':
net/core/pktgen.c:2906:3: error: implicit declaration of function 'csum_ipv6_magic' [-Werror=implicit-function-declaration]
   udph->check = ~csum_ipv6_magic(&iph->saddr, &iph->daddr, udplen, IPPROTO_UDP, 0);
   ^

Caused by commit c26bf4a51308 ("pktgen: Add UDPCSUM flag to support UDP checksums") from the net-next tree.

I added this commit:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Mon, 29 Jul 2013 16:21:26 +1000
Subject: [PATCH] pktgen: add needed include file

Fixes this on PowerPC (at least):

net/core/pktgen.c: In function 'fill_packet_ipv6':
net/core/pktgen.c:2906:3: error: implicit declaration of function 'csum_ipv6_magic' [-Werror=implicit-function-declaration]
   udph->check = ~csum_ipv6_magic(&iph->saddr, &iph->daddr, udplen, IPPROTO_UDP, 0);
   ^
