Older kernel version might have fewer values defined, so they would send
netlink messages that got rejected. Only check that at least one value
got sent.
This is especially grave as libnl uses an internal copy of the
kernel header files. Thus not only it is bound to the installed kernel
headers but to the libnl internal header copies that might easily be out
of sync with the kernel.
This affects IFLA_PROTINFO, inet6_parse_protinfo():
- tb[IFLA_INET6_CONF], expecting DEVCONF_MAX
- tb[IFLA_INET6_STATS], expecting __IPSTATS_MIB_MAX
- tb[IFLA_INET6_ICMP6STATS], expecting __ICMP6_MIB_MAX
and IFLA_AF_SPEC, inet_parse_af():
- tb[IFLA_INET_CONF], expecting IPV4_DEVCONF_MAX
