Do we need to block this patch due to the exiting PKT_RX_EIP_CKSUM_BAD
definition?

I already added the author of the PKT_RX_EIP_CKSUM_BAD flag and ethdev and mbuf
maintainers in this list. So what else I need make forward progress
on this patch?

I think, the definition of PKT_RX_EIP_CKSUM_BAD based on HW capability. It
is safe to assume that ALL HW can support CKSUM BAD if the feature is
available and hence it is more portable.
