From: Konstantin Ananyev <konstantin.anan...@huawei.com> When running l3fwd in ACL mode, if we'll have mix of IPv4/IPv6 packets in the same burst, it will most likely cause a crash. The reason for that is that we split our burst of packets into 2 arrays - one for ipv4, another for ipv6 for classify(). But then we try to send all packets as one burst again, not taking into account that acl_search.res_ipv4[] will be set only for ipv4 packets. Same story for ipv6. The fix is straightforward: use two already split arrays for TX.
