The new item type is added for the case user wants to match traffic
based on packet field compare result with other fields or immediate
value.
e.g. take advantage the compare item user will be able to accumulate
a IPv4/TCP packet's TCP data_offset and IPv4 IHL field to a tag
register, then compare the tag register with IPv4 header total length
to understand the packet has payload or not.
The supported operations can be as below:
- RTE_FLOW_ITEM_COMPARE_EQ (equal)
- RTE_FLOW_ITEM_COMPARE_NE (not equal)
- RTE_FLOW_ITEM_COMPARE_LT (less than)
- RTE_FLOW_ITEM_COMPARE_LE (less than or equal)
- RTE_FLOW_ITEM_COMPARE_GT (great than)
- RTE_FLOW_ITEM_COMPARE_GE (great than or equal)
V3:
- fix code style missing empty line in rte_flow.rst.
- fix missing the ABI change release notes.
V2:
- Since modify field data struct is experiment, rename modify
field data directly instead of adding new flow field struct.
