Flex item API provides support for network header with a fixed and
variable lengths.
When PMD compiles a new flex item object configuration it converts
RTE parameters into matching PMD PARSE_GRAPH parameters and checks
the parameter values against port capabilities.
Current implementation mismatched PARSE_GRAPH configuration fields
for the fixed size header.
