if_bridge.h uses struct in6_addr ip6; but does not include the in6.h
header.
Found by trying to build libvirt and connman against 3.8-rc3 headers.
Ok,
ignore this patch, it's not the correct fix as it introduces
redefinitions...
Btw, the error that I hit that made me suggest this fix was libvirt
config check bailing out:
config.log:/usr/include/linux/if_bridge.h:173:20: error: field 'ip6' has
incomplete type
Hmm, just now noticing this thread, after independently hitting and and
having to work around the same problem in libvirt:
https://www.redhat.com/archives/libvir-list/2013-January/msg00930.html
https://bugzilla.redhat.com/show_bug.cgi?id=895141
Yep,
and the commit breaking uapi headers is by using "struct in6_addr ip6" is:

Does the following patch help?

Well, I suggested the same fix in the beginning of the thread
on netdev and lkml: "if_bridge.h: include in6.h for struct in6_addr use"
as it seemed to fix the libvirt case
but then asked it to be ignored after I tried to build connman,
and hit this conflict with glibc-2.17:

So I'm not sure it's the right one...
