Hey Rahul,

Sorry for the late response. Just a small comment:

We would need the corresponding RTE_FLOW_ITEM_TYPE_* specified in pattern.
i.e RTE_FLOW_ITEM_TYPE_IPV6 must be in pattern for action RTE_FLOW_ACTION_TYPE_SET_IPV6_SRC
otherwise RTE_FLOW_ERROR_TYPE_ACTION return.
Would be better to document this in comments and __rte_flow.rst__

What do you think?
