> Add modify field support for GENEVE option fields:
>  - "RTE_FLOW_FIELD_GENEVE_OPT_TYPE"
>  - "RTE_FLOW_FIELD_GENEVE_OPT_CLASS"
>  - "RTE_FLOW_FIELD_GENEVE_OPT_DATA"
> 
> Each GENEVE TLV option is identified by both its "class" and "type", so
> 2 new fields were added to "rte_flow_action_modify_data" structure to
> help specify which option to modify.
> 
> To get room for those 2 new fields, the "level" field move to use
> "uint8_t" which is more than enough for encapsulation level.
> This patch also reduces all modify field encapsulation level "fully
> masked" initializations to use UINT8_MAX instead of UINT32_MAX.
> This change avoids compilation warning caused by this API changing.
