Hi Andrew, 
Almost all the comments are addressed in V11, please help to review. Thanks.
Here, since device just writes back 0 or 1 in descriptor, can’t distinguish Ipv4 or IPv6, we set RTE_MBUF_F_RX_IP_CKSUM_GOOD here. It follows ice or iavf implementation.
BTW, there's no common code in common/idpf currently, only base folder, there'll be some comment codes shared by idpf and a new PMD in next release.
