That's for ABI only and you missed the API part. Meaning, you need also mention that all APIs have port_id parameter will be changed too. Also, rte_eth_dev_data is not the only structure has ABI changes. There are few more (for instance, rte_port_ethdev.h). As said before, you don't have to list all of them, but at least you should not list one example only as it seems that's the only structure has ABI change. > + Change the definition of port_id from 8bits to 16bits in order to support > + more than 256 devices in DPDK. 8bits -> 8 bits. You might want to reword it further. Besides that, this change is indeed needed.
