I was asking only bout Mellanox cards.

Alright then.

Oh but because currently they are called like:
if (MLX5_CAP_ESW_EGRESS_ACL(dev, ft_support)) {
err = init_egress_acl_root_ns(steering);
....
if (MLX5_CAP_ESW_INGRESS_ACL(dev, ft_support)) {
err = init_ingress_acl_root_ns(steering);
....
and it could cause bigger problems if only one kind were supported,
like trying to setup egress while it's not supported by the card.
But again, as it seems both are always supported, that's no issue.
Thanks,
