ila: ipv6/ila: fix nlsize calculation for lwtunnel
The handler 'ila_fill_encap_info' adds two attributes: ILA_ATTR_LOCATOR and ILA_ATTR_CSUM_MODE. nla_total_size_64bit() must be use for ILA_ATTR_LOCATOR. Also, do nla_put_u8 instead of nla_put_u64 for ILA_ATTR_CSUM_MODE. Fixes: f13a82d87b21 ("ipv6: use nla_put_u64_64bit()") Fixes: 90bfe662db13 ("ila: add checksum neutral ILA translations") Reported-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Acked-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S.
