Newer kernel versions require this flag to be present contrary to older
ones. Depending on the libnl version it is added or not.
Typically when using rtnl_link_inet6_set_addr_gen_mode, the netlink
packet generated may contain the following attribute:
with libnl 3.4
{nla_len=16, nla_type=IFLA_AF_SPEC},
[
{nla_len=12, nla_type=AF_INET6},
[{nla_len=5, nla_type=IFLA_INET6_ADDR_GEN_MODE}, IN6_ADDR_GEN_MODE_NONE]
]
with libnl 3.7
{nla_len=16, nla_type=NLA_F_NESTED|IFLA_AF_SPEC},
[
{nla_len=12, nla_type=NLA_F_NESTED|AF_INET6},
[{nla_len=5, nla_type=IFLA_INET6_ADDR_GEN_MODE}, IN6_ADDR_GEN_MODE_NONE]]
]
Masking the type is likely needed in other places. Only the above cases
are implemented in this patch.
