[dpdk-dev,06/13] ethdev: make dev_info generic (not just PCI)
Checks
Commit Message
The result from rte_eth_dev_info_get should have pointer to
device not PCI device. This breaks ABI but is necessary.

I don't think that exposing the device through dev_info makes this a
future proof. If we want to model some kind of extensions to dev_info
we should instead model this explicitly.
So from my point of view the pci_dev should get removed instead.

+.. * Add a short 1-2 sentence description of the ABI change that was announced in
the previous releases and made in this release. Use fixed width quotes for
``rte_function_names`` or ``rte_struct_names``. Use the past tense.
- This section is a comment. do not overwrite or remove it.
- Also, make sure to start the actual text at the margin.

-
+* The ``rte_eth_dev_info`` structure no longer has pointer to PCI device, but
+ instead has new_field ``device`` which is a pointer to a generic ethernet device.
