In order to add support of the GENEVE header variable length
options the rte_flow_item_geneve_option item will be introduced:

struct rte_flow_item_geneve_option {
    rte_be16_t option_class;
    uint8_t option_type:7;
    uint8_t critical:1;
    uint8_t length:5;
    uint8_t rsvd0:3;
    uint8_t data[];
};

This option (one or multiple) must follow the rte_flow_item_geneve
item and provide the pattern to match with GENEVE header option.
