Hi Thomas,

When a new member (function pointer) is added to struct eth_dev_ops (as the=
 last member), does it need to go through ABI chance process (e.g. chance n=
otice one release before)?

IMO the answer is no: struct eth_dev_ops is marked as internal and its inst=
ances are only accessed through pointers, so the rte_eth_devices array shou=
ld not be impacted by the ops structure expanding at its end. Unless there =
is something that I am missing?

My question is in the context of this patch under review for 17.5 release: =
http://www.dpdk.org/ml/archives/dev/2017-February/057367.html.

Thanks,
Cristian
