ipv6: fix redefinition of in6_pktinfo and ip6_mtuinfo
Both netinet/in.h and linux/ipv6.h define these two structs,
if we include both of them, we got:
/usr/include/linux/ipv6.h:19:8: error: redefinition of ‘struct in6_pktinfo’
struct in6_pktinfo {
^
In file included from /usr/include/arpa/inet.h:22:0,
from txtimestamp.c:33:
/usr/include/netinet/in.h:524:8: note: originally defined here
struct in6_pktinfo
^
In file included from txtimestamp.c:40:0:
/usr/include/linux/ipv6.h:24:8: error: redefinition of ‘struct ip6_mtuinfo’
struct ip6_mtuinfo {
^
In file included from /usr/include/arpa/inet.h:22:0,
from txtimestamp.c:33:
/usr/include/netinet/in.h:531:8: note: originally defined here
struct ip6_mtuinfo
^
So similarly to what we did for in6_addr, we need to sync with
libc header on their definitions.
