iptables commit 933400b37d09 ("nft: xtables: add the infrastructure to translate from iptables to nft") added an additional member to struct xtables_match and struct xtables_target. This change is available for libxtables12 and up. Add these members conditionally to support both newer and older versions. Fixes: dd29621578d2 ("tc: add em_ipt ematch for calling xtables matches from tc matching context") Signed-off-by: Eyal Birger <eyal.birger@gmail.com> --- include/xtables.h | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+)
