[PATCH] This patch validate a connection tracking state when matching 'conntrack is' in rte_flow rules. The conntract possible CT states are SYN_RECV, ESTABLISHED, FIN_WAIT, CLOSE_WAIT, LAST_ACK and TIME_WAIT. Therefore the maximum possible value to match on in rte_flow is TIME_WAIT but mlx5 allowed matching on any values.

[Khadem Ullah]

This patch validate the CT state item.
